DSP Subwoofer Power Amplifier Rack Mout Active Switching Power Professional Audio Amplifier

This A1000 amplifier is designed for use with high wattage passive subwoofer speakers such as in-wall subwoofers or home theater subwoofers that require external power.This is a highly efficient Class D subwoofer amplifier that serves up 1000W RMS  @4ohm for deep, crisp, clean low-frequency sound effects in dedicated home theater systems and media rooms.

Compact but powerful, the A1000 power amplifier buit-in DSP (Digital Signal Processor) for high performance at low clock freqiencies and improve bass response of subs. You can control the DSP by knob or remote, and allows users to edit in user mode or in PC. You can see the functions showing on the display.
