DAS Audio Integral A402 2-Channel Install Amplifier

The Integral A402 is a dual-channel, 1U Class D amplifier built for permanent installation. It runs on a universal switching mains supply and drops into auto-standby when no signal is present, so it does not draw power on an idle system. Rated 2 x 200 W into 4 ohms, it can also be switched to bridge mode for a single 400 W output feeding a 70V or 100V distributed line.

Inputs and outputs land on euro-block terminal connectors, with an IEC inlet for AC. The rear panel switches between stereo and bridge mode and can engage an 80 Hz, 12 dB/octave high-pass filter. Front-panel LEDs report power, protection, standby and signal/clip status, so a technician can read amplifier health without opening a rack.
