Monitor Remote Encoder Failure
The rotary encoder on MONITOR-ST remotes can wear or miss steps, causing erratic volume control or automatically engaging DIM. Dangerous Music specifically identifies encoder contact wear as a cause of this behavior.

Professional Audio
End Use Segment
Dangerous Music, Inc. is a U.S. manufacturer of high-end professional studio audio electronics designed primarily for recording, mixing, and mastering engineers. Its product portfolio centers on analog summing mixers, monitor controllers, mastering processors, equalizers, compressors, analog routing/switching systems, headphone monitoring equipment, and high-quality A/D and D/A converters. The company grew out of custom mastering-console and transfer-console design work for facilities including Masterdisk, Hit Factory, Sterling Sound, and Absolute Audio, and became particularly associated with bringing mastering-grade analog signal paths and high-fidelity monitoring to DAW-based studios. Products such as the 2-BUS/2-BUS+, BAX EQ, COMPRESSOR, MASTER, LIAISON, SOURCE, MONITOR ST, and CONVERT series reflect its emphasis on transparent signal processing, analog workflow, and critical monitoring.
2 Most Seen Failures:
External Power Supply Failure
External AC/DC power supplies can fail, become intermittent, or stop powering the unit entirely. Dangerous Music specifically documents failed or deteriorating power adapters on SOURCE units.
Remote Communication Failure
MONITOR-ST/SR remotes can lose communication with the rack unit, resulting in unresponsive controls, incorrect switching, or apparent system lockups. Reconnecting or resetting the remote may temporarily restore operation.
Relay Switching Failure
The numerous electromechanical relays used for source selection, speaker routing, and stepped attenuation can develop worn or unreliable contacts. Symptoms can include missing channels, intermittent audio, incorrect levels, or failure to switch inputs or outputs.
Intermittent or Missing Audio Channel
A left or right channel may become weak, intermittent, distorted, or completely absent because of relay contacts, connectors, analog-stage components, or power-rail problems. This can affect monitor controllers, summing mixers, converters, and mastering processors.
Digital Input Lock Failure
CONVERT, DAC-ST, DAC-SR, SOURCE, and other digitally equipped models can fail to acquire or maintain synchronization with AES, S/PDIF, ADAT, or USB sources. Clocking, digital receiver, connector, or associated power-supply faults can cause dropouts or complete loss of digital audio.
Control/Firmware Lockup
Digitally controlled Dangerous Music hardware can occasionally become unresponsive and require a reset or power cycle. A published MONITOR-ST review documented a remote/system crash that was subsequently addressed with firmware.
Noisy or Intermittent Controls
Aging potentiometers, switches, encoders, and connectors can develop intermittent contact, producing crackling, level jumps, dropouts, or inconsistent control response. Models using conventional potentiometers are particularly susceptible as their mechanical controls accumulate wear.
Analog Power-Rail / Power Regulation Failure
Failed regulators, capacitors, rectifiers, or other power-supply components can produce low output, distortion, excessive noise, intermittent operation, or a completely dead unit. Heat and inadequate rack ventilation can accelerate component aging, which is why Dangerous Music recommends ventilation around its rack hardware.

- 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.
