Key Digital KD-AMP220 — 2 x 20 Watt Class D Amplifier

Compact Class D amplifier from Key Digital. The KD-AMP220 delivers 2 x 20 Watt and can blend a microphone feed with the selected audio source for a single output. Each input features its own adjustable volume, while output controls provide variable volume plus bass and treble adjustment. Accepts both pre-amp line level and speaker level signals. Operation mode is user-selectable: stereo, bridge, or mono. A built-in noise gate keeps levels consistent and helps reduce ambient background noise. Control options include front-panel controls, RS-232 integration, and IR control with an external IR sensor, all in a small footprint for easy system integration.
