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.
Cetacea Sound Corp. is a U.S. professional-audio manufacturer specializing in compact sound reinforcement and voice-amplification systems for classrooms, training rooms, and other small group-listening environments. Founded in 1996 and based in Plymouth, Minnesota, the company designs and manufactures its products in the United States. Cetacea is particularly known for its Astronaut ceiling-mounted powered speaker systems and patented omnidirectional acoustic approach, intended to distribute speech and multimedia audio evenly throughout classrooms while emphasizing vocal intelligibility. Its product portfolio also includes Astronaut Soundfield classroom voice-amplification systems and Orbiter wireless pendant microphones for teachers and presenters. The company's systems are designed for straightforward installation and integration with projectors, interactive displays, computers, televisions, and existing AV equipment, with education representing its principal market alongside corporate training, healthcare, government, and institutional applications.
Astronaut and Ensemble systems may show no power or no green status LED due to a failed 15V power supply, damaged DC connection, or incorrect/unapproved adapter. Cetacea specifically warns that unsuitable power supplies can permanently damage the amplifier or other internal components.
Powered Astronaut, Ensemble, and Soundfield systems can power on normally yet produce no sound because of failed or loose input connections, source-output problems, amplifier faults, or incorrect source settings. Cetacea identifies poor connections and poor audio sources among the most common causes of speaker problems.
Astronaut systems can develop a pronounced continuous buzz when an audio input or cable is left electrically unterminated. Cetacea recommends terminating speaker cables through the source and/or the supplied inline volume attenuator because the amplifier input is not gated.
Astronaut and Soundfield systems can exhibit persistent hum or background noise when long unbalanced 3.5 mm cables pick up electromagnetic interference. Poor shielding, cable routing, grounding, or deteriorated audio cables can make the problem substantially worse.
Astronaut and Ensemble amplifier circuitry can fail prematurely when driven from excessive line-level signals, amplified outputs, bass-boosted sources, equalizers, or other signal-processing modes. Cetacea documentation explicitly warns that overdriving its amplifier stages can cause premature hardware failure.
Orbiter pendant microphones may fail to establish a wireless connection with the Astronaut Soundfield or Orbiter Commander, typically indicated by the absence of the solid amber connection LED. Pairing problems can also occur when incompatible V1, V2, and V3 microphone/receiver hardware is mixed.
An Orbiter pendant may power on and appear connected while transmitting no usable microphone audio because of receiver, output connection, volume-control, or microphone-path problems. A connected receiver should display a solid amber LED, making no-audio faults distinguishable from basic pairing failures.
Orbiter pendants can fail to power on or maintain operation when the internal battery is depleted or the charging system is not functioning correctly. Cetacea directs users with no green power LED to place the pendant on its charger and verify charging activity before further troubleshooting.
Astronaut and Ensemble systems may produce distorted, weak, or otherwise degraded sound from excessive source level, poor connections, damaged cabling, amplifier stress, or transducer problems. Cetacea specifically cautions against excessive source volume and signal-processing effects because they can overdrive the system and ultimately damage it.
