How to connect additional speakers to a PC. How to connect speakers from a music center

Useful tips

It is very convenient to listen to music or watch a movie on a personal PC. The absence of annoying advertising and the ability to stop watching a movie at any time are a significant advantage over television viewing. Yes and availability special programs allows you to communicate with friends and family at any time of the day. But in order for sound to be transmitted, the computer must be equipped with speakers. For users who have nothing to do with technology, it is sometimes very difficult to connect audio equipment. In our article we will look at how to connect speakers to a computer without an amplifier.

How to connect passive speakers to a computer?

The presence of two RCA inputs on the speakers, the so-called tulips, allows you to connect using a Mini jack audio cable (3.5 mm jack) to 2 RCA. Mini jack must be connected to a sound card that has a green output when using them as front speakers or as a stereo pair. Or you can use a 2 RCA-2 RCA audio cable and a mini jack adapter that operates on 2 RCA inputs.

Each column has 2 terminals. In this case, you can completely use a cable from any headphones with a 3.5 mm mini Jack. For this:

You should carefully cut off the speakers and thoroughly strip the wire.
After this, connect the stripped ends to the terminals, and the mini Jack to sound card.

Important! If you want to find a use for a decent music center, then it is best to purchase an inexpensive stereo amplifier, which will fully justify your costs.

At similar method connecting speakers to a computer, you will not be able to achieve high-quality sound effect due to the low power indicator, the output will be only a few watts. But this option is quite justified, since in any case, to function as a passive speaker, you need to connect an amplifier. Otherwise, the speakers would simply gather dust on the shelves or, as unnecessary, they would have to be thrown into the trash.

How to connect active 5.1 speakers to a computer?

Before you start connecting speakers to your computer, you need to carefully study the capabilities of your audio card. To do this, you need to figure out how many inputs your PC’s sound card has. Once you know the number of “sockets” on your computer, you can make a connection. When connecting 5.1 speakers, you will have to use several jacks.

How to connect old ones active speakers to a computer without an amplifier:

We select the green cable from the speakers, which is the signal cable.
We connect it to the audio output connector, which is located on the rear plane of the system unit and has exactly the same green tint.
Turn on the computer.
We turn on the speakers and check the sound.

Important! If there are no sound levers in the speakers, then you should find a subsection on the control panel that is responsible for audio devices and sounds.

After that, turn on the “sound”.
Already in the panel we adjust the volume.

How to connect active 5.1 speakers to an old computer?

If your PC is an old modification and a little outdated, then the connection process is slightly different from the previous method. To connect active 5.1 speakers you need to do the following:

We connect the cables to the connectors. To do this, you need to navigate the volume control module by colors.
We connect the power supply, subwoofer, and speakers, paying attention to the polarity of the connectors.
We connect cables of the appropriate colors to the computer connectors.
We connect the front speaker cable to the green output.
We connect the rear speaker cables to the blue connector.
We connect the subwoofer cable to the pink input.
If necessary, we also connect a microphone to the pink connector.
We configure the computer by selecting six-channel mode.

How to connect a speaker system to a computer?

In principle, connecting ordinary speakers to a computer is not difficult, but connecting speaker system can cause a lot of difficulties for many users. In such a situation, there are several methods to solve this problem.

How to connect speakers to a computer without an amplifier? — First you need to determine the number of outputs or sockets that the sound card has in your computer.

System 7.1

For modern built-in sound cards, it is possible to use 7.1 acoustics, which is indicated by colored sockets on the motherboard. Each color has its own purpose:

green output, related to the front or so-called front speakers;
the orange plug supports the center channel and subwoofer;
black socket - for rear or rear speakers;
exit gray directed to the side speakers, or they are also called surround speakers;
blue tint socket is used for line input, which can be used, for example, for a player, electric-acoustic guitar;
The pink output operates the microphone.

System 5.1

To connect speakers to a 5.1 speaker system, you will have to use several sockets that have the corresponding shades - green, orange and black. Here's how to connect to your computer passive speakers and a 5.1 subwoofer from the acoustic center:

On the rear panel of the system unit, we connect the cable with a green plug to the audio output connector, which is also green.
Based on the colors, we connect the remaining cables to the corresponding connectors on the sound card control module.

Important! While connecting the cable to the sound card, the program displays which type of speaker corresponds to a specific socket. As a result, all three of the above-mentioned connectors must be used.

We connect the subwoofer and speakers with an RCA-RCA cable, and connect one end of the cable to the subwoofer, since most often it contains an amplifier. We connect the other end to the corresponding speaker.

Important! To make sure there is no mistake, each RCA output on the subwoofer is labeled based on the type of speaker.

We set up the computer, select six-channel mode and use the sound card driver application, Windows Sound Control Panel.

Important! If you have a 7.1 speaker system, you will have to additionally use the gray connector on the motherboard to use side speakers.

As a last resort, you can use the instructions for the motherboard, especially when you have to connect the headphone and microphone jacks on the front panel of the system unit of the computer device.

Connecting speakers to a computer via S/PDIF (digital output)

When you connect 5.1 speakers via SPDIF, you will have to prepare an SPDIF cable. For this purpose, you can use both optical and coaxial cable:

Coaxial - SPDIF inputs and outputs are made on RCA type connectors. The digital signal is transmitted via a regular cable with appropriate connectors. A device that receives interference impulses filters them out, but there is still a possibility of losing some data.
Optical SPDIF uses optical cable to transmit data. Inputs and outputs are made on Toslink type connectors, closed with plugs. Their presence helps to very quickly determine the type of interface. In addition, Creative sound cards also use an optical interface using a mini Toslink cable. The optical cable does not respond to magnetic fields, since data is transmitted in the form of light pulses. Therefore, there is an opinion that optical interface digital data transfer occurs much more best protection from external influence than coaxial. Satellite receivers are used exactly optical type SPDIF interface.

Important! When choosing a connection type, you must take into account the type of interface for the connection external sources signal on the amplifier housing of the used speaker system. To do this, you need to connect the cable to the digital output on the motherboard and connect it to the desired digital input connector on the speaker system. In the audio card interface, you should change the output port, while changing analog signal to digital. Unless, of course, the driver has the ability to determine the connection to the digital output itself.

How to connect speakers for games?

How to connect passive speakers to a computer without an amplifier? Games are able to output sound directly, without using various compressions. Therefore, it is still not possible to create larger stereo sound from a game via S/PDIF.

To correct this shortcoming, you need to purchase a sound card that can support Dolby Digital Live or DTS Connect. These technologies have the ability to instantly encode multi-channel audio from a game in 5.1 or 7.1 digital signal Dolby Digital or DTS and transmit directly via S/PDIF. In the practical operation of one of the described technologies, all audio played on the analog outputs is re-encoded and sent to digital S/PDIF.

Let's look at how to get 5.1 sound from any source, for this:

In the sound card settings, select one of the presented 5.1 audio encoding technologies: Dolby Digital Live or DTS Connect.
In the settings panel Windows sound select the main device analog outputs sound card.

User Misconceptions

Not owning necessary information, some users have misconceptions that can significantly complicate the process of using speakers. Let's look at the most common ones:

When the game ends, you must switch to the initial state to correct operation. If one of the on-the-fly encoding technologies is always enabled, then you will not be able to view and listen to files with multi-channel audio. Since they are encoded, they must be output directly to S/PDIF.

Important! In fact, you shouldn't switch anything. When watching a movie in stereo, it is displayed at 5.1. When you watch a video with a DTS or Dolby track, the sound is perfectly distributed across channels. This situation is very clearly visible even on a player that has the ability to switch audio tracks eg The KMPlayer.

The process of on-the-fly encoding of a stereo signal from an mp3 file using DTS Connect or Dolby Digital Live is several times inferior to the hardware decomposition of such sound on a receiver or speakers.

Important! This is wrong. When connecting acoustics of similar quality to the receiver, no significant difference is observed. The main thing is to adhere to the following condition, under which you do not forget to disable the options in the settings of THX Studio Pro or in a similar “equalizer” of the sound card. Otherwise, they are created various effects, for example, a voice may stand out on a common background picture sound. In addition, the sound card plays a big role. Creative Titanium HD does this very well.

How to connect active speakers to a TV?

How to connect speakers without an amplifier not only to a computer, but also to a TV? There is nothing difficult about connecting speakers to a TV. For this, two RCA-RCA or tulip-tulip cables are used. First you need to determine the presence of RCA inputs on the rear panel of the speakers. The presence of RCA inputs allows you to connect some ends of the cable to the L and R outputs, and the other to the speakers.

Important! If the speakers have only one cable with a mini Jack at the end, then the connection is made into the headphone jack on the TV.

When connecting a music center, an RCA-RCA cable is also used, which is connected to the L and R outputs television device. After this, the AUX mode is set on the music center, the RCA cable is connected to AUX input, located on the rear plane of the music device.

In this article we have covered everything possible options speaker connections. We hope that now you have no questions about this, and you can get high-quality sound for any purpose.

Computers or laptops are not always equipped with powerful sound speakers. And quite often we lack the power of sound. And when there are guests or small children in the house, you have to listen at all in order to watch a movie normally or listen to your favorite music. In our article we will tell you how to connect speakers to your computer easily, simply and without outside help.

How to connect regular speakers to a computer

There are many connectors located on the back panel of your PC system unit. Manufacturers specifically designate them in different colors. With the help of such simple tips, you can independently navigate where to connect the speakers, microphone, mouse, printer, monitor. Almost all modern motherboards already have built-in ones sound cards. Speakers are connected to the computer via a 3.5 mm mini-jack, which is usually indicated in green.

Now turn on the computer and speakers and check. If you did everything correctly, but the speakers still do not work, there may be a problem with your operating system. Windows usually downloads and installs itself. necessary drivers. If, after connecting, the driver window does not pop up, then you need to reinstall them. You can use installation disk, which comes complete with audio speakers. Check your mixer to make sure all channels are turned on and the volume is adjusted.

Note: if you purchased speakers whose plug connector is larger than the mini-jack, you will need a special adapter. You can buy it in all electronics stores or order it online.

How to connect car speakers to a computer

If it seems to you that this is from the realm of fantasy, then it is not so. Typically, car speakers are passive, and if you simply connect them to a connector or through an adapter, there will be sound, but it will be very quiet. Therefore, in order for the speakers to work properly and perform their direct function, you will need an amplifier. Which one will suit your speakers depends on the manufacturer, the speakers themselves and the expected result. The most correct decision in this case would be to go to good store acoustics, where they will definitely tell you what to do.

Connecting the speaker system

If you want to connect not just sound speakers, and a subwoofer, microphone and other devices, you need a speaker system. You may encounter some difficulties when connecting it. Therefore, try to follow the instructions that we have prepared for you:

Usually there is a green audio connector on the back panel of the system unit, and the signal cable must also be inserted there;
now turn on the computer and the speakers themselves;
check the sound. Quite often, you can adjust the purity of the sound and configure the system using the buttons on the system itself. If they are not in the Toolbar, find Audio sound and turn it on;
if you still need to connect additional devices(microphone, subwoofer) your PC must have a special sound card. It can be purchased separately.
Now you can easily organize a real concert at home or organize a small cinema for your family and friends.

After you have read our article, you can easily connect sound speakers to a computer of any complexity and configuration.

How to properly connect and phase speakers?

In this article we will talk about connecting speaker systems to an audio power amplifier (APA).

If you find an old Soviet amplifier and speakers in your closet or on your balcony, then do not rush to throw them away. By connecting all these rarities to the linear output of your computer, you can get good results for practically nothing.

The disadvantage of many Soviet amplifiers was poor tone control circuits. When using a computer as a signal source, you can easily compensate for this shortcoming by using a software equalizer that comes with any sound card.

A few words about the power of speaker systems.

Speakers (speaker systems) differ in the amount of signal power supplied. There are rated, maximum and peak powers. Peak power is sometimes called maximum short-term power and even the duration of its exposure is specified.

It must be said that the value of speaker power, due to the importance of this parameter for a large group of music lovers, is interpreted differently by marketers. Often, for marketing purposes, the maximum permissible power is significantly overestimated.

As for Soviet speakers, the value of the maximum power supplied to them can be found in the accompanying documentation or here.

The documentation usually indicates two parameters, rated and nameplate power.

Rated power is the input signal power at which the speaker system can operate for a long time without significant distortion.

Nameplate power is the input signal power at which the speaker can supposedly operate limited time. In fact, using this parameter for practical purposes is quite problematic when it comes to multi-way speaker systems.

Judge for yourself. For example, you have at your disposal an audio amplifier with a power of 2x100 Watts at a load of 4 Ohms and the once popular 35AC (S90) speakers with a resistance of 4 Ohms with a nameplate power of 90 Watts.

If we connect such an amplifier to a computer and, using an equalizer, direct all the signal power to high-frequency speakers (tweeters), the power of which is only 10 watts with a resistance of 8 ohms, then it turns out that we can direct about 50 watts of power to a dynamic head designed for rated power only 10 watts and the nameplate, say, 20-30 watts. In other words, in this situation, only a miracle can save the “tweeters” from destruction.

The golden rule for connecting speakers is that the power of the speakers in any case exceeds the power of the amplifier, and the greater this excess, the better for the speakers.

Multi-way speaker systems.

Speaker systems differ in the number of frequency bands into which the amplifier's output signal is divided.

In single-way speaker systems, the entire output of the amplifier is sent to one or more identical speakers.

In two and three-way speakers, the amplifier signal is separated using passive filters that are located inside the speaker housing. Such systems use dynamic heads designed to reproduce a certain audio frequency band.

Speakers are divided into four groups: high-frequency, mid-frequency, low-frequency and full-range. By their name you can guess what frequency range they reproduce.

There are also multi-band speaker systems that do not contain bandpass filters. Such systems require a signal already divided into bands corresponding to the sound heads. In such cases, multi-band amplifiers or external filters (crossovers) are usually used.

Connecting speakers.

In the simplest, but most common case, the signal from the amplifier is supplied to the speaker via a two-pole cord. The cord has either a detachable connection to the speakers or a permanent connection.

The plug connection may look different, but in any case the terminals are marked one way or another. If there is no “+” marking, then the red color of the terminal is considered a plus.

On the opposite side, the cord must either have a plug for connection to the amplifier, or simply bare ends if the amplifier is equipped with special clamp terminals.

Soviet speakers were connected to Soviet amplifiers using three types of plugs.

The picture shows forks in the order of appearance in the trading network.

Five-pin plug (sometimes three-pin of a similar design);

Double-pole plug designed for mechanically secured sockets;

Double-pole plug for sockets intended for printed circuit mounting.

Type “2” plugs differed from “3” type plugs in that one of their contacts was shorter and, in some cases, this led to the fact that they did not provide reliable contact with sockets intended for printed circuit wiring.

When connecting speakers to the amplifier, the polarity of the connection must be observed.

Assignment of pinouts (pinout) of the plug.

"Frame"- connects to the amplifier body, which is connected to the common power cable.

"+" (plus)- connects to the output of the power amplifier.

As a cable, you can use any suitable multi-core two-wire cable, including a network cable. However, it is better to use a special audio cable, which can be found on the radio market. In such a cable, one of the wires is either painted or marked, which makes it easy to maintain the polarity of the connection.

Connection diagram of the amplifier to the speaker.

The figure shows a diagram of the correct connection of a low-frequency amplifier to the speaker system.

The red arrow indicates the direction of movement of the low-frequency dynamic head cone, with a positive half-wave voltage at the amplifier output.

If you connect a battery instead of an amplifier, you can easily phase the speaker systems if the cable is not marked and there is no means for testing the cable.

We are finalizing Radio Engineering S-90 (35AC-212) Nameplate power... 90 W

Rated power... 35 W

Nominal electrical resistance... 4 Ohm

Frequency range... 31.5-20000 Hz

Nominal sound pressure... 1.2 Pa

Overall dimensions of the speaker... 360x710x285 mm

Speaker weight no more than... 30 kg

S-90 is a classic of Soviet column construction. According to the manual, the S-90 speaker system is designed for high-quality reproduction of sound programs in combination with various types of household radio equipment.

Well, for the early 80s these were truly outstanding speakers with high sound quality. However, foreign speaker construction is developing, and already at the beginning of the new century, the sound of the S-90 is perceived differently.

High frequencies sound disgusting, there is simply NO mids! And if we talk about bass, then a similar effect will be when placing a healthy bass player in a large kick drum... The lows drone on in black. It is impossible to listen to D&B style music; IDM also hits the ears. What can we say about classics and calm music. After an hour or two of listening, my ears begin to hurt (however, my head and stomach hurt no less). Despite these shortcomings, many people buy these speakers.

All of the following applies to Radiotechnika S-90a (AC35-212) speakers. This is one of the very first releases (and one of the best), characteristic features - 2 controls on the front panel, HF and midrange speakers shifted from the center, paired speakers, 4 Ohm impedance. However, the meaning of the modification and the modification itself can easily be applied to other S-90 (S-90b, S-90F, etc.), their analogues (Orbit, Amphiton, etc.), as well as to homemade speakers . The main criterion is the presence of 3 bands (speakers) and a bass reflex. The modification of speakers with a closed cabinet (i.e. without a bass reflex) is somewhat different, I will write about this later. And one more thing - there are many options for improvement, so in some places I will describe 2 methods. You will choose the most suitable one yourself.. I will not write a list of necessary materials - in most cases, everyone uses what is in this moment most accessible.

1) Disassembly

We take one speaker and place it on the floor with its back wall (this is the most convenient way to remove the speakers). Using a figured screwdriver, unscrew the 6 bolts securing the decorative plastic trim from the bottom of the column. Using a flat-head screwdriver, unscrew 4 bolts and remove the decorative nameplates from the speakers and the protective grilles.

Next, you will need a heated soldering iron! Then we unscrew the 4 bolts securing the woofer and carefully lift one side of it and remove it from the housing. We unsolder the wires (you can, of course, mark which one was soldered where - but it’s better to then check the diagram and solder it 100% correctly) and put it aside. We take out the midrange speaker from the housing (it was secured with a nameplate) along with the glass in which it stands. Unsolder it and put it to the woofer. We take out the HF (tweeter) - it was also attached with a nameplate and unsolder it. If there is no mark on it at one of the terminals (+), we mark which wire was soldered where, then we look where it goes according to the diagram and find “+”. We put it with the other speakers.

Be careful with diffusers! The speakers can only be grasped by the magnet or diffuser holder supports!!! Unscrew the 4 screws on the bass reflex and carefully remove it from the housing. It is held on by sealant, the main thing here is not to use excessive force - it may break! We take out 2 “sausages” of cotton wool from the body (if it is there). We unscrew and remove the filter from the housing (it can be either on an iron chassis or on a wooden plank). The wires going to it can be cut off with wire cutters (they still need to be replaced early). That's all with disassembly! Now we need to finalize and assemble.

2) Modification of the case - it is advisable to strengthen the back side of the case with wooden slats (attached with screws and epoxy). It is also necessary to place a wooden spacer in the center of the speaker (between the rear wall and the front) at the level of the midrange glass. (the main thing is to pay attention to the possibility of then installing a bass reflex!!!) This is necessary to reduce vibrations of the body - turn it up loud and put your hand on it - the body shakes! You also need to check the tightness of the housing at the joints and, if necessary, coat the joints with epoxy glue or sealant.

3) Refinement of the filter: You will need a diagram.

The point is to remove the switches from the circuit, replace the wires with audio made of oxygen-free copper, solder the speakers directly to the filter, solder the supply wire directly to the filter and shorten the signal path

In the absence of finances, you can also supply suitable copper ones from the Soviet Union. The point of selecting wires is to have a multi-core wire for the woofer, the larger the better (but not less than 2.5 mm2, and it’s bad to solder more than 4 mm2), for the midrange you can have a multi-core of at least 1.5 mm2, and for the high-frequency one you can have a single-core of at least 1 mm2 (I recommend using a core from a twisted pair cable of the fifth category for + and -). It should be said that the selection of wires is a delicate matter. There are still fierce discussions about the choice of wire for speakers. I express my personal opinion. I advise you not to skimp and buy at least the cheapest audio cable! The sound quality greatly depends on it! Take my word for it.

I also highly recommend remounting all the filter parts on a small piece of plywood/wood, so that you can place the filter on the bottom of the speaker, next to the bass reflex. This is important (especially if the filter is mounted on an iron plate). Attach the inductors to new board It is necessary not with iron screws, but with something plastic or mounted on epoxy. So, we replace all the wires on the filter board - we install it directly to the outputs of the capacitors, removing the contact plates from them.

I will not give the sequence for replacing the wires. As well as tips on where to solder the wires from the bass, midrange and treble. I hope you figure it out :). If you can’t cope, invite knowledgeable person(one that can distinguish a capacitor from a resistor will do). As a last resort, write to me by e-mail [email protected]. We're done with the filter - put it aside.

4) Hull damping:

The point is to, if possible, absorb and dissipate all standing waves inside the housing. The criterion for choosing a material is that the denser and thicker it is (felt), the better it absorbs; the thinner and lighter it is (sintepon), the worse it is. The best way to make a pancake is to coat the body with sound-absorbing mastic (automotive mastic will do), then glue a layer of felt under 1 cm + the low-frequency part with another such layer and stick chaotically pieces of felt on top. They also recommend covering it with a layer of material for kitchen hoods - I don’t know, I haven’t seen it. I did this myself - everything is upholstered with 1.5 cm felt + the bottom part is another 1.5 cm + pieces. The sound absorber must be glued throughout the entire inside of the housing. After installing the first layer of felt, I recommend placing a filter board (with wires soldered to it) and a bass reflex port on the bottom of the speaker (otherwise you won’t be able to put it in later!), placing the remaining layers of sound absorber while closing the filter. and also wrap the bass reflex with a sound absorber (the main thing is not to cover the internal section of the pipe and maintain direct access from the bass diffuser to the bass reflex). It is necessary to look at the internal volume of the case - you cannot reduce it excessively - it will affect the depth of the bass! The body is finished.

By the way, I advise those who want to find household felt, about 1.5 cm thick.

5) Midrange speaker and its glass.

I highly recommend replacing the standard 15GD-11A (or its clone) with a broadband 6-GDSH-5-4 or 6-GDSH-5-8. The difference between them is that the first has a resistance of 4 ohms, and the second has 8 ohms. Accordingly, when installing 6-GDSH-5-8, the filter does not need to be changed, and when installing 6-GDSH-5-4, put a 4 Ohm large resistor (6-10 W) power. Resistor R3 (4.3 Ohm) from the midrange divider (columns 35AC212) is just suitable for this. Don't worry about losing power with this swap! You will only benefit in sound quality. The method has already been tested on many S-90s, negative reviews no, the power has not decreased. Moreover, competitors for the 6-GDSh-5 still need to be looked for (even among foreign analogues). And this is when the cost of a pair of these broadband speakers (new!) is $4-6. They have only one minus - appearance. Although I like it :).

For the midrange you need to make a PAS. This means covering the windows of the diffuser holder on the back of the speaker with a layer of foam rubber 0.5-0.8 cm thick. Quilted batting will also work. It is convenient to cut a strip of foam rubber 4-5 cm wide and a length equal to slightly less than the perimeter of the speaker, sew it and stretch it over the windows (for 15GD-11A). Then sew with threads to the supports. We made a PAS (be sure to do it - it degrades the quality factor, which is vital for almost all Soviet midranges used in the S-90 15GD11, and even more so!) - you can install the glass and speaker in place. Insert the glass into the body and wrap the outside in 2-3 layers of a good, dense sound absorber. It is convenient to cut off a boot boot from a felt boot that is suitable in height and width, place it in the body, and then place a glass of midrange in it. The inside of the glass also needs to be covered with a layer of sound absorber (felt is just right). The purpose of such damping is to eliminate the influence of the low-frequency head on the midrange. Then you need to put fluffy cotton wool in the glass and you can put the midrange speaker in place. First check that its phasing is correct.

When you connect a 1.5V AA battery + to + the speaker, and - to -, the diffuser moves forward. Checking phasing is important! We solder the wires to it (+ according to the diagram to + on the speaker) and place them in the housing through the rubber gasket, between the midrange and the glass. Rubber 2-3mm thick. It is convenient to use window rubber insulation made in the form of hollow tubes and with a self-adhesive side.

We install the speaker, seal it with plasticine and screw it on top with a nameplate, placing rubber gaskets on the screws between it and the speaker. It is better not to install a protective grille - it spoils the sound. Have you seen good imported speakers with grilles on the speakers? When installing 6-GDSH-5 under the nameplate, you will need to put rubber gaskets about 1 cm thick on the screws.

More about the midrange speaker. If you don’t want to install another midrange driver, you can modify the old one, for example like this. Although if you have a speaker with a rubber, rather than fabric, surround, it’s better to go for the 6GDSh!

This sweet word is cotton wool... It greatly affects both the overall sound and the bass in particular! So one day I reduced its amount by half. The speakers began to emit not bass, but some kind of hum...

So, we sew a couple of gauze bags (35 cm by 35 cm) and fill them with cotton wool from the 2 sausages that were removed from the body, so that almost the entire sausage goes into the first bag, and less than half of the second into the second bag. Fluff the cotton wool. We place these bags in top part housings for socket

HF and next to the midrange glass. We fluff the remaining half of the cotton sausage and simply throw it on the bottom of the column, on the filter wrapped in felt. In my opinion, this is the best placement of cotton wool in these columns.

7) HF head.

Solder according to the diagram. We put it into the body through a rubber gasket and screw it on top with a nameplate. We also don’t install a protective grille! Uhh... A hell of a job has been done, but there is very little left! Let's continue.

8) woofer.

We solder it (it is advisable to check the phasing, as well as the midrange) and place it through a rubber gasket (required!), fasten it with bolts, again through rubber washers and seal it with plasticine sealant. We put a nameplate on top.

9)End of assembly.

We install the plastic front, tighten all the bolts and wipe the front panel.

Yes - a few little things (quite important!): run the wires to the HF and MF under a layer of sound absorber, and wrap them around the LF; carefully check the phasing, keep in mind that the bass and midrange in the S-90 are connected in antiphase; be sure to place the speakers on rubber pads; remove all parts from the plates of the disconnected HF and MF dividers, and cover them with a sound absorber; don't skimp on wires; remove the grilles; do not suffocate the volume; the bass reflex pipe must communicate freely with the surface of the speaker diffuser; gauze is clamped inside the bass reflex pipe - it is needed there; place the speakers on spikes (for example like this); It is better to immediately solder the connecting cable to the filter; it is much cheaper than buying good connectors.

To watch a movie with sound or listen to your favorite music on your computer, you need to connect speakers or headphones to it. Let's figure out how to connect speakers to your computer. The connection method depends on the type of sound-producing devices - wired or wireless.

Wired speakers can be either very inexpensive or advanced music centers. Wires may get in the way on the desk, but such devices reproduce sound without any problems even on old PCs.

How to connect speakers to home computer or laptop:

Place the speakers on the table. For harmonious sound reproduction, place the right and right left side- they are usually marked by the manufacturer with the letters R and L, respectively. In the absence of designations right hand Install the speaker that has the power cable coming from it.
Plug the power cable into a power outlet; if you have miniature USB speakers, connect them via a USB cable.
To directly connect the speakers to your computer, start on the right side. Insert the cable tulips into the speaker connectors, matching the colors of the sockets - place white in the port with a white outline, red - with a red outline.
Insert the third end of the wire into the computer audio jack located on the back or front panel. The corresponding slot is highlighted in green.
Connect the right speaker to the left using a wire in two tulips.
All that remains is to turn on the music to check the functionality of the devices.

Along with the speakers, you can also use a microphone, transmitting from it sound signal.
