About the M8

The Acurus M8 is a high-performance 8-channel power amplifier engineered and manufactured in the USA. It uses a patented Class D amplifier topology that is highly efficient, quiet, and free of audio distortion. Each channel delivers 200 watts into 4-8Ω loads when all channels are driven, with bridged mono mode providing 320W into 4 channels and 400W into 4Ω loads. The amplifier features a frequency response of 20Hz to 20kHz with ±1dB variation, total harmonic distortion (THD) under 0.05% at 200W (8Ω), and a signal-to-noise ratio (SNR) of 112dB (A-weighted). It has a damping factor greater than 1000 at 8Ω and 50Hz, input impedance of 20kΩ, and supports speaker loads of 4Ω and 8Ω. Control interfaces include RS-232 serial, Ethernet with web interface and TCP/IP control, 12V trigger, and infrared remote. The amplifier is housed in a black satin anodized 2RU chassis with laser-etched logo and white rear panel, measuring 17" W x 3.5" H x 15" D and weighing 31 lbs. It is suitable for residential media rooms, multi-purpose rooms, light commercial, and marine applications. The M8 supports mobile app control and third-party control drivers, and comes with a 5-year warranty. Optional accessories include a rack ear kit (ARM-3).
