No Power / Blown Fuse
The unit does not power on, or its mains fuse blows immediately. Repair reports on IN-series amplifiers associate persistent fuse blowing with failed power-stage components, including MOSFETs and voltage-regulator circuitry.

Repair, Service, and Parts
Acme Revival is an independent repair network that operates separately from the manufacturers whose devices we service. Our independence enables a repair model that exists beyond manufacturer-controlled strategies, while preserving the ability to work with manufacturers where appropriate.

High-End Audio
End Use Segment
Atoll Electronique is a French high-fidelity audio electronics OEM founded in 1997. The company designs and manufactures audiophile-oriented equipment including integrated amplifiers, power amplifiers, preamplifiers, DACs, CD players/transports, network streamers, and related audio electronics. Its products are assembled, tested, and finalized at its approximately 500 m² manufacturing workshop in Brécey, Manche, Normandy, where PCB component placement and soldering, electronic testing, chassis assembly, adjustment, listening tests, and final inspection are performed. Atoll emphasizes French and European sourcing, with many mechanical and electronic components supplied by specialized regional manufacturers. The brand is particularly known for French-made, discrete-component hi-fi amplification and for retaining a comparatively hands-on manufacturing and testing process rather than outsourcing finished-unit production. Its products are distributed through roughly 100 sales locations in France and in around 40 countries internationally.
2 Most Seen Failures:
No Audio Output
The unit powers on normally but produces no sound from either channel. Causes range from source/input and connection faults to protection or power-stage failures after an electrical fault.
One Audio Channel Dead
One speaker channel produces no output while the other operates normally. Atoll documents this symptom across its amplifier ranges, with speaker/interconnect connections being the first checks before an internal channel fault is suspected.
Power Output MOSFET Failure
One or more output MOSFETs fail, potentially causing loss of audio, excessive current draw, or blown fuses. Documented IN100SE and AM100 repair cases show failed power-stage devices following electrical or thermal stress.
Thermal / Bias Circuit Failure
The amplifier runs excessively hot or components in the power stage overheat and eventually fail. Repair analysis of older IN/AM designs identifies thermal management and bias-temperature control as potential contributors to power-stage damage.
Protection Circuit Shutdown
The amplifier enters protection, mutes its output, or shuts down after detecting excessive operating conditions. Atoll amplifiers use protection circuitry and output relays to disconnect the loudspeakers when abnormal current, voltage, or power conditions occur.
Wi-Fi / Network Connection Failure
Atoll network players may fail to connect to the network or repeatedly lose their Wi-Fi connection. Atoll specifically identifies antenna installation, wireless signal strength, distance, and network configuration as common areas to check.
Streamer Freezes / Stops Responding
Network players such as the MS120 and ST200 can become unresponsive during operation. Atoll's troubleshooting procedure calls for a HOME-key reset or complete power restart when the device stops responding.
USB Storage Not Recognized
Atoll streamers sometimes fail to detect or read an attached USB flash drive or storage device. Atoll identifies incompatible filesystem or media formatting as a primary cause of this symptom.

- 1 Repairs are performed on a best-effort basis. Acme Revival utilizes a network of sophisticated technicians and engineers with diverse service offerings; despite this, factors that influence the repair outcome may ultimately prove unsuccessful. Acme Revival makes no claim that it can, guarantee a repair before your device is sent in for diagnostic evaluation; even then, repair and diagnostic work are not mutually exclusive. Despite well-intentioned quoting, repairs may still prove unsuccessful.
