No Power / Power Supply Failure
Unit fails to power on, powers intermittently, or shuts down unexpectedly. Aging or failed PSU components, internal power distribution faults, and heat-stressed components are common areas to investigate.

Professional Audio
End Use Segment
BURL Audio is an American boutique professional-audio equipment manufacturer founded in 2006 by engineer and recording-studio owner Rich Williams in Santa Cruz, California. The company specializes in high-end recording, mixing, and mastering hardware and is particularly known for its B80 MOTHERSHIP and B16 MOTHERSHIP modular audio interfaces, B2 BOMBER ADC/DAC converters, B1 microphone preamps, B32 Vancouver summing mixer, B26 ORCA monitor controller, converter daughter cards, word-clock hardware, and related studio electronics. Its design philosophy combines modern digital conversion with substantial analog circuitry, including discrete Class-A electronics and proprietary transformer designs, to retain analog character in digital recording workflows. BURL is especially associated with its modular MOTHERSHIP conversion platform, which supports professional formats including DigiLink, MADI, Dante, and SoundGrid and is intended for recording studios, mastering facilities, broadcast, film, and other professional production environments.
2 Most Seen Failures:
Digital Clock / Synchronization Failure
B2 Bomber and MOTHERSHIP systems can exhibit clicks, pops, distorted audio, loss of synchronization, or failure to lock to an external clock. Clock configuration, word-clock circuitry, digital interface hardware, or associated daughter cards should be checked.
Missing Audio on One or More Channels
Individual inputs or outputs may stop passing audio while the remainder of the unit continues operating normally. Likely fault areas include analog signal-path components, connectors, daughter cards, discrete amplifier stages, and local power rails.
Intermittent / Distorted Audio
Channels can develop crackling, intermittent signal, abnormal distortion, or reduced output. Heat-stressed analog components, connectors, solder joints, discrete Class-A circuitry, and power-rail instability are primary suspects.
MOTHERSHIP Daughter Card Failure
BAD, BDA, or other MOTHERSHIP daughter cards may stop communicating or lose one or more channels. Card-edge connections, module power, configuration, firmware compatibility, and the daughter card itself should be isolated during diagnosis.
Network / Dante / SoundGrid Connectivity Failure
Network-equipped B2 and MOTHERSHIP configurations can fail to appear to the host, lose connection, or stop passing audio over the network. Interface-card configuration, firmware, network hardware, clocking, and sample-rate mismatches are frequent diagnostic areas.
Overheating / Thermal Instability
BURL's discrete Class-A circuitry produces substantial operating heat, particularly in converter hardware. Poor rack ventilation or heat-related component degradation can lead to intermittent operation, noise, shutdowns, or accelerated PSU and component aging.
Mic Preamp / Gain Stage Failure
B1 and B1D microphone preamps can develop loss of gain, noisy or distorted output, intermittent input, or phantom-power problems. Likely causes include switches and controls, input circuitry, transformer connections, discrete gain stages, and associated power rails.
Word Clock / Sample-Rate Configuration Problems
Converters may produce periodic clicks, aliasing, unstable audio, or apparently malfunction despite otherwise functional analog circuitry when source and converter clock settings disagree. BURL's B2 documentation specifically requires correct clock-source and sample-rate configuration, making clocking one of the first areas to eliminate before board-level repair.

- 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.
