The Dolby® Multichannel Amplifier is an advanced, high-density design that can replace up to 16 stereo amplifiers. With less equipment to install, power, and maintain, you get a simpler and more efficient installation. The Dolby Multichannel Amplifier is available in three configurations, with 16 channels (DMA16302), 24 channels (DMA24302), or 32 channels (DMA32301), and includes enhanced power handling for lower impedance loudspeakers. The 16-channel (DMA16302) and 24-channel (DMA24302) configurations provide an 8-channel analog input module that allows direct integration with the Dolby Digital Cinema Processor CP750 and other cinema sound processors used in 5.1/7.1 surround sound installations. The Class D amplification topology is designed to deliver high-performance audio quality on every channel.


The Dolby Multichannel Amplifier is designed for reliability. It includes a custom-built power supply with built-in redundancy, power sharing, operational monitoring, and fault detection. The Dolby Multichannel Amplifier power supply enables the system to operate from a 100 to 240 VAC, 20 amp service without tripping the AC main circuit breaker. The Dolby Multichannel Amplifier automatically detects maximum and net power availability, as well as certain operational and environmental conditions, and adjusts channel gains based on power supply, load, and fault conditions.
