PSB-1000DSP Sub Amplifier

The Soundavo PSB-1000DSP powers passive subwoofers and provides DSP controls to tune their bass response. Its front-panel LCD, IR remote and RS-232 interface suit home-theater and installed-audio systems.

At a glance

• Up to 1000W RMS into a single 4-ohm load, or 500W RMS into an 8-ohm load.
• DSP adjustment of crossover, slope, phase, volume and limiting.
• Three saved bass settings, plus 12V trigger input and output.
• 2U rack format with short-circuit and thermal protection.

Is it right for your system?

This is a subwoofer amplifier for passive speakers. Match both impedance and power handling to the amplifier. For the manufacturer's dual-subwoofer connection, use two 8-ohm subwoofers; the two terminals do not make it a stereo full-range amplifier.
