Transparent equipment repair process
From diagnostics to stress testing, you always know what you're paying for.
1
Input diagnostics
Accurately identify the cause of the failure using oscilloscopes and thermal imagers. Free with subsequent repairs.
2
Transparent coordination
We never present you with faits accomplis. First, we come up with an estimate and a deadline—then we get to work.
3
We carry out repairs
We don't replace entire boards; we resolder specific components. This is several times cheaper than buying new components.
4
Deep prevention
Cleaning from dust and "liquid", replacing thermal paste and lubricating coolers to prevent future breakdowns.
5
Final inspection
Mandatory stress test on a stand for 24 hours to eliminate the risk of repeated failure.
6
Issue and guarantee
You receive a working device, an official work certificate, and an extended 6-month warranty.
Why professionals choose us for audio repair
We repair the consequences of unqualified intervention. We restore circuit board tracks and remove leaks and jumpers left behind by other technicians.
Deep expertise
We know the difference between "simple soldering" and "repairing circuitry." Our engineers understand the specifics of the equipment and know how a properly functioning device should operate.
Diagnostics on the stand
We use frequency generators, oscilloscopes, and spectrum analyzers to detect not only obvious faults but also hidden distortions (THD) that ruin the sound.
Documentary support
We work with legal entities under VAT-compliant contracts, providing technical reports and all necessary closing documents.
Cost of repairing sound equipment
| Input diagnostics | Free for repairs |
| Power amplifier repair (output protection, power supply, cascades) | from 7500 rub. |
| Mixing console repair (faders, channels, power supply) | from 7500 rub. |
| Repair of active acoustic systems | from 5500 rub. |
| Digital Console/DSP Processor Repair | from 7500 rub. |
| Repair of a radio system or microphone | from 3500 rub. |
| Device maintenance (cleaning, thermal paste, lubrication) | from 5500 rub. |
The exact cost is determined after a free diagnostic. The estimate is agreed upon before work begins and remains unchanged.

Professional repair of sound equipment and acoustic systems
Failure of acoustic systems or amplifiers at a commercial facility always poses a risk of disrupting operations. Our company provides professional repairs of acoustics, musical equipment, and concert sound for restaurants, hotels, theaters, and conference halls. We tackle projects of any complexity, restoring equipment from leading global manufacturers.
Component repair: we restore, not replace, modules
Most services offer expensive, complete board replacements. Our lab takes a different approach: component repair of audio amplifiers and other complex electronics.
We carry out precise diagnostics and repair of burnt-out audio components at the microchip level. Engineers find the specific cause of the malfunction: a burned-out transistor, a broken capacitor, or a damaged track. resoldering components on the amplifier board or processor allows us to significantly reduce the final cost and repair time for the customer. We carry out complex repair of audio equipment boards, restoring power supply circuits, amplification stages and DSP modules.
What problems do we fix?
Our audio equipment service center has the necessary instrumentation base to service the entire audio chain:
- Repair of audio and power amplifiers: We restore both concert rackmount equipment and 100-volt background sound systems. We perform spot amplifier repair, we eliminate protection mode, background noise and overheating.
- Acoustics and monitor repair: we conduct professional speaker repair and crossovers, replacement of high-frequency drivers and membranes. We're taking on the job. repair of active acoustic systems, passive tops and subwoofers.
- Restoration of the concert apparatus: replacement of motorized faders, encoders, restoration of input/output boards of digital and analog consoles.
- Complex music speaker repair any form factor after falls, liquid spills or power surges.
Repair of mixing consoles
The mixing console is the center of the entire sound system, and its failure brings the entire venue to a halt. We carry out repair of mixing consoles Any class: from compact analog consoles to digital systems from Allen & Heath, Yamaha, Midas, and DiGiCo. Typical work includes: fader replacement and cleaning, including motorized ones, eliminating noise and crunch in channels, preamp repair, restoring +48V phantom power, replacing encoders and buttons, repairing touchscreens, and updating firmware. Mixer repair It starts with diagnostics on the bench: we run the signal through all channels and buses, localize the faulty path, and replace specific components, not entire boards.
DJ equipment repair
A separate direction - DJ equipment repairWe service DJ controllers, media players, and mixers from Pioneer DJ, Denon DJ, and Native Instruments. We replace jog wheels and encoders, restore faders and crossfaders, repair connectors and built-in audio interfaces, and repair spills—a common affliction of club equipment. After repairs, the equipment undergoes a test run under load.
Service center in Moscow and the Moscow region
We receive sound and music equipment daily from all over the city, ranging from individual units to complete sound systems. Large equipment requires careful transportation—you can bring it to our technical lab yourself, or we can arrange for a specialist to pick it up from your location. If you require Speaker repair in Moscow or reliable Sound equipment repair in Moscow and the Moscow region With a fair guarantee on resoldered components, entrust your equipment to our engineers.
Frequently asked questions
An amplifier going into Protect mode is a common malfunction that we troubleshoot at the component level. Common causes include output transistor breakdown, a faulty power supply, overheating due to a dust-clogged cooling system, or a short circuit in the speaker line. We determine the exact cause using diagnostics on a test bench with an oscilloscope.
Yes. The most common failure points in active speakers are the built-in amplifier modules and switching power supplies—we repair them down to the component level. We also replace faulty speakers, high-frequency drivers, and membranes, and repair crossovers.
Noise and crunching are usually the result of fader and potentiometer wear or contact corrosion. We clean and replace faders, including motorized ones, and restore preamps and +48V phantom power. After repairs, the signal is routed through all channels and buses on the stand.
Yes, but speed is key: don't turn on a flooded device and bring it to a service center as soon as possible. We clean the circuit boards, remove traces of corrosion, and replace damaged components. We repair mixers, active speakers, and DJ equipment after flooding—this is the most common breakdown for club equipment.
We repair professional audio equipment from leading manufacturers: Yamaha, L-Acoustics, d&b audiotechnik, Meyer Sound, JBL, RCF, Electro-Voice, Dynacord, Allen&Heath, Midas, DiGiCo, Shure, Sennheiser, and others. We have access to service documentation, so our repairs are performed in accordance with manufacturer specifications.
