Compact digital amplifier and pre-amp 

• Mixes microphone input with selected audio source and can provide phantom power to microphone
• RS-232 controllable volume, muting, mic mix level and more
• Pre-amp ideal for integrating into 70V audio systems with output reflecting volume, mixing and muting settings applied
• 20 watts per channel at 4ohm, 40 watts at 8ohm bridged

KD-AMP220 is a 2x20-watt Class-D amplifier with an 8Ω speaker output ideal for installation in presentation spaces.

Input connections accommodate microphone, line level balanced/unbalanced, and line level 3.5mm stereo analog audio inputs.

The output is a mix of audio from the microphone input and the selected audio input.

Microphone and output volume levels may be variably controlled via IR, RS-232, or the front panel, and speaker level output may be set to bridge stereo or mono mode.
