SMP500DSP High Power Subwoofer Amplifier 400W RMS/1000W Peak 4 Ohm Stable W/ Remote Control

OSD Audio’s SMP500DSP is a highly efficient Class D dedicated subwoofer amplifier that supplies passive subwoofers up to 1000W power peak power/400W RMS 4 ohm stable, so you can enjoy all the crashes, crunches and car chases with spine-tingling exhilaration.

OSD Audio’s SMP500DSP Class D Subwoofer Amp is designed for use with higher wattage passive subwoofers such as in-wall subs that require external power. This is a highly efficient Class D subwoofer amp that serves up 1000W of power peak and 400W RMS @ 4 ohms for deep, crisp, clean low-frequency sound effects in dedicated home theater systems and media rooms.

Compact but powerful, the SMP500DSP includes a built-in Digital Signal Processor (DSP) for high performance at low clock frequencies and improves bass response of subs with a variable high-cut filter with a front panel control knob that routes higher frequencies to main speakers.

Compatible with new and old-school source equipment includes both signal (low level) and speaker (high level) pass through input/outputs for greater flexibility. Loaded with high-end features at an affordable price, the SMP500DSP includes front-mounted power meter, auto power on/off and dual 110/220 voltage.
