How to make an active column from the music center. Recommendations to those who decided to upgrade the music center. Installation of acoustics

First of all, it should warn that it will be discussed here that you can change without changing the design of the device itself. Usually in all music centers, the developers have already adjusted all its components to each other. But, as always, by additional financial (and not only) investments, it is possible to achieve quite good results approaching your center to samples of Hi-Fi equipment or at least make it more functional and pleasant to hearing.
So, what still can be improved in the music center and how much can it do?

Step 1. Let's start with the costs that will be connected directly directly from the financial side (although how to see :)). Usually most owners column are standing next to the central block. Yes, it looks impressive, but sounds ... Yes, and often at the high volume, the CD player is knocked down in the center. The optimal location is the following: in width - as wide as possible, in height - just below the level of the human ears sitting at the place of listening. Ideally, of course, put the columns on the racks, but it is first, it costs money, secondly, you need to look for a place to put them. To support the bass, you can put a column in the angles of the room (especially helps for those speakers that have a hole of the phase inverter from behind, but for them a distance is at least 10 cm., Otherwise there will be no bass). It is advisable to avoid setting the columns in the niche, because At the same time, the reproduction of average frequencies (in particular, the voices and the leading tool). You can safely put columns on furniture items, such as cabinets, tables, etc., not forgetting to stick on the specks of the legs. Sometimes they come in a set with the center, sometimes - already stuck on the columns, but most often they are simply not. In this case, they can be made themselves. In total, not less than 8 ordinary plumbing pads (4 per column) are required. They glue on the bottom of each column by any glue for glowing rubber and chipboard, for example, "moment", closer to the corners. By the way, due to the fact that lately The design occupies far from the last place in any industry, it is worth considering this and with an arrangement of acoustics, more precisely, at its position. It often happens that the departure from the classic speaker arrangement scheme (strictly on the same line and in one plane) sharply narrows the possibility of arrangement of the speakers. For example, many music centers should not put the side columns (which is often done when placing them on the mezzanine). In the case of an asymmetric arrangement of speakers, take into account that it is more correct to position the columns so that the HF speaker (small, sometimes dome) is from the outside relative to the central block, which will allow at least a little bit, but expand the stereo tap.
We now turn to the expenditures that are starting to require free economic resources :). Here are several options. Let's go in order.

Step 2A.. The easiest and easier financially dangerous - cable change. It should be warned that it will be painless only for owners of those centers that have clamps both on the device itself and on columns. The rest will have to disassemble the columns, which during the warranty period I clearly do not advise do - immediately lose the guarantee. What cables should be taken? In a word - inexpensive. And if more precisely, then inexpensive cables (up to $ 5 / meter.) Scright up to 2.0 sq. M. (more - more expensive, and it will not fit into spring clips, which are equipped with most centers) and well-known firms. You should not take unknown cables on the same construction market, which, according to the seller, acoustic. It is usually unknown that. Separate word owners block mini microsystems. In this case, it is possible to replace both interblock cables. There is also no expensive here. It will be enough to take a meter cable up to 20-30 $ (at a lower length price below). When connecting additional devices (it will be discussed next). Use again inexpensive cables. The fact is that music centers are almost the lowest class of audio engineering, in which expensive cables will first of all be economically impossible, in addition you will not get a cardinal change to sound for those big money that will be paid for the expensive cable. The difference will, but not so much to take a 10-$ cable instead of a cable for $ 50-80. Rather, even so: the difference between the standard lace and tenollast will be more noticeable than between the thirtydollar and eightythydollar (this applies only to the music centers). In addition, the more expensive cable can set all the shortcomings of the center of the bottom and you will no longer want to listen to it :(.

Step 2b.. Purchase subwoofer. It is no secret that many owners of musical centers love to listen to the pogrom and so that the bass! ". Usually rarely which speakers can issue a deep bass without distortion. Therefore, there is a special column for low and sublife frequencies, called subwoofer. It is intended not only to "bum", and above all for high-quality bass transmission. Subwoofers are passive (just a drawer with a speaker) and active (with its own amplifier). Active subwoofers The lion's market share is now constituted. Usually, the centers can be painlessly connect the second type of subwoofers, however, provided that the center has a special output (Sub Out). Active subwoofers are better than passive not only by the fact that they have their own amplifier (which allows not to strain the amplifier of the music center), but also flexible in adjustments. Active subwoofer can be placed anywhere on the floor, excluding niches and angles (otherwise the bass will be very humble). If there is no special output to the subwoofer, then you will have to look for a passive subwoofer or an active subwoofer with high-level inputs and outputs. Passive cheaper, but also has a lot of minuses: it is critical to the installation site, the impossibility of adjustments, uses the resources of the music center. It connects to the gap between the central block and speakers: the wires for the columns will first go to the subwoofer, and from it - on the speakers. What to take a subwoofer? It is necessary to take into account the method of connecting the subwoofer to your center and first of all proceed from this. Again, you should not take expensive subwoofers. The upper limit for the subwoofer for the music center is $ 500. Many good models for music centers around $ 100-200

Step 2V.. Replacing acoustics. This is probably the most interesting upgrade of the center that allows you to radically change the sound of the device. What is the acoustics? Acoustics is outdoor and shelf. What prefer? Based on the room area:

Room Square, m2	AC
less than 10.	tower coil, big coil
from 10 to 18	large flightman
from 18 to 22	large Top, Small Golf
from 22 to 25	small, medium galler
over 25.	middle, large gallery

Treasher - usually two-wire speakers with a height of about 30-40 cm.

A large turnover - two-three-band speakers with a height of about 50-60 cm.
Small Galler-Double-Wandered speakers with a height of about 70-80 cm.
The average gallery is a two-three-fold speaker of about 80-100 cm high.
A large gallery - three-four-fold speakers with a height of about 100 cm. And above

But the choice of acoustics is not limited to the choice on the area of \u200b\u200bthe room. Important (and rather, even decisive) factors will be resistance (impedance) and power. Usually, music centers are designed for 4-6 ohms resistance, but there are those that are calculated on 8 ohms. If it is written that you can connect the 8-ohm and higher acoustics, then 6 and the more than 4-ohmic acoustics cannot be. It threatens the failure of the output stage of the amplifier (expensive non-warranty repair). At best, the current protection will be triggered, but, agree, it is very unpleasant to listen to music, accompanied by temporary sound disconnections. The maximum output power must be at least the maximum output power of the center. Rated power is usually 1.5-2 times lower than the maximum. This power at which the AU will work normally without distortion and damage. Remember: not every expensive acoustics will give you what you want from it. Acoustics for music centers have a tangible rise in bass (100 Hz) and high (10 kHz), but further than these frequencies there is a rather strong decline. In an inexpensive acoustics, we approach these frequencies less, but it is. In addition to more wide range Frequency. There is no expensive acoustics of this lifting and at first it seems that there are no bass, nor the tops (the usual delusion of people who are accustomed to listen music Center). Therefore, you should not spend on acoustics more expensive 250-400 $. It is also worth paying attention to such a parameter as sensitivity. This is essentially the volume of the speakers. Most columns are muses. This indicator varies from 76 to 88 dB. Inexpensive acoustics up to $ 350 has a sensitivity of 82 dB to 91-93. High sensitivity directly contributes to the fact that even a low-power SAMSUNG with 5 watts on the channel will scream as a center for $ 1000.

Step 2g.. Acquisition of additional devices. Very often, manufacturers recommend to expand the capabilities of the center. Additional devices: MD- and CD recorders, recorder players, DVD players, etc., suitable, first of all, in size and design to the existing apparatus (for which, by the way, is often quite a lot. Money with limited functionality). I dare to assure: Any device (except for the player of the plates) can be safely connected to the center for playback (if there is AUX IN), and often on the recording (AUX OUT). And it is not necessary to accurately comply with the name of the entrance (again, with the exception of the entry for the records player): It may be called as you like: Line in, Aux in, MD in, Video in, Game in, but this is the same. So you can safely connect almost any device. The whole question is, whether it is necessary for you?
In conclusion, I want to say: the music center, unlike block equipment, is a complete system, subject to limited upgrades (and sometimes even limited to conduct), so any intervention must be strictly realized and clearly for itself is formulated. And if all this is fulfilled, the result will please you.
Successful to you upgrade!

Good luck!

Music centers, released ten or more years ago, are outdated and morally, and technically, but any of them can be cited. After a modification, such a device will be able to play music from memory cards and from streaming services.

For assembly, we will need:

Old musical center.
- Any smartphone (you can get cheap and even without battery).
- Memory card adapter (MicroSD adapter to SD).
- a piece of plastic.
- Printed circuit board, radiator, transistor LM317 and two resistors (240 and 510 Ohms).
- 3.5 mm Jack and toggle switch (optional).
- Wires, soldering iron.
- Bolts and nuts.

Remove the cassette mechanism and drive from the music center optical disks. Leave only the amplifier, radio, AUX-input, control buttons and scoreboard.

Cut out the plastic cover that closes the hole formed after you broke the cassette deck and CD drive.

Make a multiple holes in the cut cover: for the smartphone, the inclusion button and the memory card adapter buttons.

Remove rear cover Smartphone and soldering wires:

- Two wires for power supply.
- Two wires from the speaker.
- Eight wires from the contact slot contacts.

Speak to the SD-adapter of the wires that go from the memory card slot according to this scheme (the condenser is not necessary):

Insert the adapter into the slot and secure it with glue. You can insert a microSD card with music.

Wires coming from the speaker, solder to the AUX input or amplifier. You can also provide AUX switching between the smartphone and external source Sound. To do this, insert Jack into the audio output of the smartphone and solder the cable from it to the toggle.

Power to a smartphone through a voltage stabilizer.

The power button must have two groups of contacts. One group commutes the inclusion of the phone, the second tape recorder. If the radio is not required, you can do with a button with one contact group.

Stick your smartphone on the thermocons and additionally fix it with plastic cambricks. Such a music center can do everything that the smartphone is capable, that is, can play music from a memory card and online services

Answers:

Dimon-:
Not directly, but through the amp, it is possible, as it is to use the center itself (there is usually there aUX entry - There you need to give a signal from a green connector on sound) or buy / collect amp.

Booster:
Only through an additional amplifier (yes through the same center).

Niko:
Only if they have the same resistance. And it is unlikely. But even if it is so - the sound will not be the same powerful. It is better to enter the speakers from the computer directly to the music center (use it as an amplifier), and then listen to the sound through the normal music center.

Leo:
Better connect the center itself with the computer.

TU-154:
Through the amplifier - you can and need. Directly - it is possible, but meaningless, so output power sound card Not enough for their work.

Andrei Fedorovich:
You can, but it is better to connect through the amplifier.

Darkart:
You can not but need! Especially if the center with the subwoofer :).

Lech-Yandex:
Depends? Vene of the center itself or the amplifier will not pull the sound. Personally, I have 2 50W speakers from the player of Yugoslav production, but they are active.

Shamann:
Directly - in no case! Give the sound! And through the center - please, in some even USB sweat for this purpose.

Alekssh76:
It is possible, but without an amplifier, it is unlikely that it turns out.

Shurovik:
Directly - no. Only through the amp.

Mike:
If you are a radio engineer, then at least to the teapot.

SSIFL:
Directly - no. Every center has linear input. Here you can connect the computer.

Zvyaginsev Pavel:
You can, only sleep the sound, not in vain the computer columns are still included in the network, there is also an amplifier.

Andrew:
Speakers cannot be connected separately from the "Center". To the computer you need to connect the music center along with the speakers.

Krugovoy, Alex:
You can, through the amplifier.

Ilyukha:
Speak to them mini Jack.

NEOS81:
You can but through the amplifier, and then the sound card is diligent. Buy a cord on one side of the tulip and on the other on both on the headphones sticky and that's it.

Agro:
Can. You take (do, buy) Lace: at one end of the minijack, on the second two tulips (or that you have at the entrance of the center). Minijacks in Line Out sounds, tulips in the Line in the center and all. IMHO: If the center is normal, not cheap for 100 rubles. And the sound is suitable, then the sound will be high-quality (generally computer columns do not go to any comparison with good from the center). At the very much done.

Konstantin Mikhailovich:
And the central speakers differ from computer, eh? Especially if you have a good sound ...

Mik:
It is necessary if you do not have SOLO2 or MERCURY50. To Audigy2 Value Hi-Fi set.

Vgreen:
Watching what sound. On almost all modern chain can only be active columns, but on the old one. In short, to stop useless disputes - I have on ESS SOLO-1 (it seems so) hanging the AC25 Soviet, the third year. Esno there are no super-duplicate bells on the old sound card, but it works without an amplifier, although it's hot :) And you probably have in general integrated, since this problem arose, because only through the center will come.

This is a question from the archive. Adding answers is disabled.

Currently, homework, consisting of musical centers, does not find a wide application and safely dust on the cabinets of the premises. In this regard, it seems that it seems to be how it has already served his age. Is it so? Equipment for music playback is high-quality and pretty expensive, so it is a pity to send such equipment on the garbage. Our article Consider the options for alternative use of the device to play music, for example, how to connect a column to a computer from the music center without center.

How to connect speakers from a working music center to a computer?

Let us ask yourself how to actually make the connection of the speakers from the stereo system to the PC. It turns out that it is quite possible. And for the functioning an acoustic device Such a connection process is not difficult at all. For this procedure, you must use only one cable, appearance Which looks like as follows:

one side of the cable is crowned with usual black minijack by 3.5 mm;
on the other side, two white and red tulips hang.

Important! There is nothing complicated in this cable, you can make it yourself, just for this you need to at least be able to properly hold the soldering iron. To do this, you need to find the cable itself, if it is not enough, you can apply the cord from stereo handers. The necessary plugs are purchased in any department of radio components in a modern hypermarket or on the market. As they say, and cheap, and angrily.

How to connect a column from the music center to the computer:

The purchased cable is connected to the AUX connector, which is located on the back of the stereo panel. These are two identical holes that have red and white.
The second end of the cable connect to the opening to exit acoustic speakers on personal Computer. It is a large hole that has a green bezel. And this is almost all.
After that, we turn on the audio system, make the AUX mode on it.

Important! Each individual music center has its own setting, which differs from others, so to connect, you must select an individual instruction or you can try to apply the method of "scientific tyka". Maybe it will be possible to guess and correctly determine the desired mode.

Now you can easily use our advice and elementary to connect stereo speakers from the audio system to a stationary PC or to a laptop, if there is a functioning most musical center. But there are cases when equipment for music playback is inoperative, how to solve the problem in such a situation?

How to connect columns from the non-working music center

This situation is much more complicated and its solution requires certain costs. The problem is that the stereo is the amplifier that feeds the speakers. Sound card power located in computer device, lacks for the rinch of acoustic speakers. Therefore, connecting the speakers from the music center to a stationary computer or laptop without the center itself, it is not easy to implement. But probably.

For this, first of all, it is necessary to find an amplifier or make it yourself. For this purpose, both a separate device and the use of cards from old speakers are useful. The main requirement is that the power of the selected amplifier is not greater power of stereo speakers.

Important! If necessary, you can independently sold out the amplifier - this is not so difficult task. There is a lot on the Internet ready-made schemes Any complexity and various options. The required details can be easily purchased in any radio house of the construction store.

Sometimes there is a computer acoustics in the house, which may have no function of several columns. In this case, it is necessary to clarify this power and work voltage, spend comparative analysis with acoustic speakers home stereo.

Important! The required characteristics are in the instructions or on the rear panel of the audio system. If the parameters are suitable, then the task is solved, and our device can be connected.

Stock foot

From the above article, it can be seen that the music center released from fashion can be easily turned into computer acoustics. To do this, it is necessary to take advantage of the entrance and some advice given in our article. You can connect AUCS to MUZ. Center and enjoy music.

The refinement of acoustics do it yourself.

You have a pair of speakers in your hands, and maybe not a couple. Active either passive. Outdoor or shelf. It may be at all a subwoofer, not a speaker.

This article will help you learn about how to improve the quality of the sound of your acoustics without extra cost. The most effective methods of refinement of acoustics, which are easy to implement their own hands will be described. This can be called grinding of what the manufacturer could not embody, by virtue of the feasibility of production and its payback.

All instructions and tips from this article are suitable for any acoustics with a phase inverter, including subwoofers and floor columns. Many tips are also suitable for other type of acoustic systems.

So, let's begin.

Corps upholstery sound-absorbing material and construction strengthening.

First, find out for what purposes this procedure is performed.

Opening speakers.

Disassemble the column is very simple.

If this is an active acoustics, then on the active column you need to unscrew the amplifying unit behind the rear, which is screwed on the screws.

It is necessary to remove the block very carefully, without sharp movements. If there are plugs that are detached, disconnect them and put the amplifying block nearby, without dragging the wires. On passive speakers - you just need to unscrew the screws on the skill dynamics and carefully remove it without damaging the wire.

* All these operations need to be taken carefully and without sharp movements, to avoid damage to the wires and circuits.

Strengthening the hull.

This modification should be carried out if you doubt the strength of the design of your acoustics and there are no additional stiffness structures inside the case (strengthening slats, "traffic jams" on the walls, screeds between the walls). Almost always, the columns need additional strengthening.

For this procedure, small 1x1 - 1x2cm bars and rubber glue will be required. Brussia we will glue along the corners, on which there is no BRUSEV, which will strengthen the adjacent side walls to each other. Memind and cut off, we apply and pretend, they smear a ram with a ram and the place to which it will be glued. We glue all the angles on which the manufacturer saved the tree. Naturally use bars as struts, and not just glue.

It is also worth paving the beams. along Long walls Columns, if any. As shown in the figure, or diagonally. Beams should fit tightly around the edges.

It is also desirable to make horizontal struts between the walls, it will significantly strengthen the design. Especially relevant for large speakers with long walls (for example Microlab Solo 7.).

After this procedure, we get a stronger construction, which creates less wall resonance, as well as less vibrations with micro-friction and touching the walls to each other.

To carry out this procedure, we will need double sided tape and Sound absorbing material.

For what goal This is done.

All this action is carried out with the aim of reduce reflection of sound waves From the acoustics housing with the phase inverter. If this is not done, then often instead of bass, incomprehensible buzzing and whistling sounds will fly out of it. Upholstery gives more smooth and balanced basswhich becomes more soft And it is better to distinguish with rumor. She removes buzzing, resonant sounds that arise in the acoustics housing due to the collision of sound waves. It also allows you to slightly expand the lower range of the reproducible frequency.

As sound absorbers, best suitable materials such as syntheton(can be found on any broad market, and you can find in the old jacket 🙂), felt, rolled Wat. or the most interesting material - vata., sound absorbing - type " URSA.", In addition, she is non-combustible. Only not insulating glasswater from quartz sand, and home for installation of partitions. If you get these materials problematic, as a last resort, you can use rolled foam, get which you can in any Hozmaga. But still its use is extremely undesirable. Do not forget that the syntheps, felt, watts before the sickness need to be fluffy.

To begin with, take out that sound absorbing material that put in the inside the manufacturer, if any.

What are we doing.

1) We glue bilateral scotch, as much area as possible inside the column, as far as possible. Immediately dug the protective paper.

2) Cut or stretch the sound absorbing material so that the bare walls are completely closed, including (especially) angles.

3) We pave the material all the cavities so that the wooden walls are completely sealed. The thickness of the layer must be no more than 2 cm, otherwise it can significantly reduce the volume inside the case, which will not be better affected at the depth of the bass component.

A warning.

In places that heated, it is better not to overdo it. It concerns places next to the transformer and the amplifier block. Between them, and the sound-absorbing material is better to leave empty space in 1-2 cm. Therefore, the best material is a non-combustible sound-absorbing cotton wool type "URSA.", Which for example, may remain after repair. It can be used without restrictions.

You need to try to consolidate the material as carefully as possible. After all, you do not want, with a large movement of the mass of the air inside the case, wool or sintepon, they jump inside or worse - departed from the phase inverter 🙂

Refinement of the phase inverter.

To reduce the rattles and a possible whistle from the phase inverter, it is worth making 2 things.

1. Verify the phase inverter with sound-absorbing material, by type "fur coat" by one layer. Leave 1 cm of your bare space on the end of the phase inverter. Tightly fasten the "fur coat" with thin rubber bands, wrapped around the phase inverter, as shown in the figure above.

2. Exactly cut with nipples, any protective grills inside the phase inverter pipe. There is no benefit from them, but there are a lot of extra pride and whistles. If the mesh is pasted on the end, it is also better to remove it. This will allow air to be easier to pass, which will increase the overall speed of the dynamics.

Installing acoustics on spikes.

Try when playing music to click on the speaker for a while. You will hear that he flashes and swallows a good half of the frequencies. It happens because the finger absorbs vibrations, not giving the dynamic to give them into the air.

Case column - This is a continuation of the dynamics. When contacting with floor, table, shelf or other things, the body of the speaker gives part of its vibrations to these objects, as in the example with the finger.

In order for acoustics to qualitatively in the air, sound waves are physically not scattered about the floor and items with which it comes into contacting the distortion, spikes apply.

Spikes are attached as legs. For this, 4 small holes (not through-through) are drilled on the lower wall, in which they are screwed. You can buy them in many household electronics stores, where acoustics are for sale and accessories to it, or order via the Internet. Under acoustics with spikes, should be solid material - Ceramic tile, parquet or other. The main thing that the legs had as little to contact him and have not worked out.

The principle of spikes is that they are strong reduce the area of \u200b\u200bcontact The speakers with the surface on which it costs. Due to this, the sound waves that are served on the body begin to sound, and not fade about the floor, parquet or shelf. Distortions are minimized, the bass component becomes more distinguishable for rumor and much more detailed.

Important note.

Spikes, makes sense to use for acoustics with decent weight and decent size. Spikes worth using predominantly for outdoor acoustics Weight more 12 kg. Or for subwoofers weighing 5 kg and more. In smaller acoustics, the effect will be, but not so noticeable.

Replacing wires on an amplifying part of acoustics. For active acoustics.

Often, the manufacturer saves on such things as the quality of the wires from the crossover to the dynamics and from the board to the crossover. Thickness, as well as the quality of the wire - directly affects the quality of the sound. The thickness of the wire, the deeper the bass and the medium frequencies. This modification is first of all to be carried out on subwoofers, due to the greater energy, which flows through these more wires.

1. We select a suitable wire for replacement, naturally copper itself high Quality What is in stock. It is desirable not a VVG (solid), since the signal when passing through such a wire is changing. It is better to take the core PVA (wicker) from oxygen-free copper. Thicker is not always better, you need something average, depending on the power of acoustics.

2 . We disappear and cut off the old wires. If on the other end of the bracket, then if possible, we solder the wires to the terminals themselves on the board. If this is not possible, cut off the bracket for the root, take out the cords, solder the wires to them and insert back to the bracket. Also wrap the terminals of the dynamics and crossover and abundantly disappear. Make sure!

3. Make sure as soldering.

It is also worth paying attention to connecting wire between columns.

The manufacturer rarely seals something sensible. The best option from the most affordable is a wicker wire with transparent insulation, which are completed, for example - Sven Royal or Microlab Solo 6. and higher.

Similar wire, you can also buy electricians in stores. It is like an inexpensive option for the replacement of the clips, which come in a set with acoustics. For outdoor options, the acoustic wires are best suitable with a thicker cross section and better, oxygen-free copper. Such can be bought at any store where home theaters are sold, or in the electronics market.

A couple of words about wires from the sound source to acoustics.

Wires that go from sound source to speakers (usually tulips) or receivers should be of good quality.

It is very desirable that they are shielded from nutritional interference, cellular networks and radio. For this, wire manufacturers turn them with a foil layer, either soaring aluminum or copper thread. It is easy to distinguish them - they are much thicker than not shielded. Also, high-quality wires should be with gilded plugs for smaller resistance and smaller signal loss on plugs. You can buy such wires on the radio market or in stores where home theaters are sold.

Note.

In order to change the wires to be a tangible effect - we advise you to replace them with a price plan for acoustics 100$ And above (for 2.0). Either, if the manufacturer uses the wire is really poor quality.

Use network filters.

Good network filters that are equipped high-frequency suppressors, it is not bad to remove the so-called white noise And other interference caused by poor-quality nutrition and interference on the network.

Often, in the circuits of built-in amplifiers, there is no high-quality interference suppression scheme, which leads to distortion, noise from speakers and different soundsWhen the fridge is starting to work or electro - Razhigig gas stove at neighbors 🙂

Remember the fact that cheap filters - in no way save you from the interference. Such can protect equipment from pulse currents that occur for example when the lightning strike is in wiring, and only.

In the filters that we need - there must be an suppressor (filter) of high-frequency interference. They are also useful for receiver and amplifiers, both for protection and better noise immunity.

Good filters make companies Zis Pilot. (starting from the series GL), APC..

If the columns are buzzing or from them there is an extraneous sound.

The reasons are usually two:

Poor quality signal source, or cable.
Low-quality input capacitors in the built-in reinforcement part (if the columns are active).

IN first case, you need to check the cable, see inserted Lee connectors fully in the plug and check integrity cables. Also need disgust Wires from others, especially from cables supplying network and radioSince they create around themselves magnetic fields.

In second caseYou need to open the column with an amplifying part. It is usually harder and has a radiator.

Next, you need to find condensers for filtering the power supply network. Usually there are two and they are the largest. They should be dropped and replaced with new, high-quality and greater maximum voltage and capacity. Also worth seeing did not swell and did not flow (brown or yellow dried liquid nearby) Others. If so, then on the replacement without thinking.

Other large capacitors can also be replaced, as they do not stand out on multimedia acoustics.

Other useful tips on improving the sound quality of your acoustics, without any modifications.

Proper alignment of acoustics.

To achieve the highest possible quality of sound, acoustics need completely arrange around the room.

30% of success in achieving the correct sound picture depends on the correct alignment of acoustics.

_________________________

1. High-frequency speakers ( HF) - must be at one level with the ear Listener for better positioning in space.

2. Port phaseinverter nothing should be closed. The distance from the wall or another obstacle should be more than 15 cm to low frequencies Not lost at the exit and nothing, did not prevent them from spreading around the room.

3. The front speakers must be placed on 30 degrees, From the point of sight of the listener and are directed strictly on it.

Rear, on 30 degrees from the side point of the listener (from 90 degrees) Only in this case is the best depth of the sound pattern.

4. Optimal distancewhich should stand the speakers from the listener - 2 meters for outdoor Columns I. 1 meter for pole.

5. Exclude extraneous sound sources. It may be open window, not quiet system unit etc. All these sounds - interfere with the perception of sound and may even make a magnificent sound - to make an inseparable and little detailed.
