Description

The BasX A-800 is an eight channel power amplifier, specifically designed for use in multi-zone and whole home applications. The BasX A-800 has eight individual amplifier channels, each of which features a carefully designed high current, short signal path, Class A/B output stage, with advanced microprocessor-controlled monitoring and protection circuitry. The eight amplifier channels in the A-800 are arranged to provide the absolute maximum in terms of flexibility: each channel may be used separately, or as part of a stereo pair; each stereo pair may be supplied with its own input signal, or receive its signal from a common stereo input bus; and each pair of channels may optionally be bridged into a single channel with higher power (for a total of four bridged high-powered channels). In addition, the BasX A-800 may be configured to be turned on manually, or by a trigger signal from a preamp or processor, or to turn on automatically when it senses an audio signal on any of its inputs.

Power Output (two channels driven)

50 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.03%; into 8 Ohms.
80 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.1%; into 4 Ohms.

Power Output (8 channels; all channels driven)

35 watts RMS per channel; 1 kHz; THD < 0.03%; into 8 Ohms.
50 watts RMS per channel; 1 kHz; THD < 0.1%; into 4 Ohms.

Power Output;  BRIDGED MODE (4 channels; all channels driven)

100 watts RMS per channel; 20 Hz - 20 kHz; THD < 0.03%; into 8 Ohms.

Broad Band Frequency Response

Individual channel mode: 20 Hz to 80 kHz (+ / - 1.8 dB).
Bridged mode: 20 Hz to 80 kHz (+ / - 3 dB).
