Mini 2-Input Class D Audio Amplifier with Mic Mixer

The KanexPro AP2DBL eliminates the need for a separate mic preamp and mixer in space-constrained AV installations. This quarter-rack-width Class D amplifier delivers 2×20W at 4Ω with a built-in microphone mixer featuring 48V phantom power, automatic ducking, and independent volume control — combining amplification, mixing, and EQ in a single compact chassis.

Two switchable stereo inputs (RCA and 3.5mm) accommodate media players, laptops, and wireless mic receivers, while the balanced MIC input supports condenser, dynamic, and line-level sources. RS232 control with a documented command set enables integration with Crestron, Extron, and other room controllers. Bridge mode doubles output to 1×40W at 8Ω for single-speaker installations, and a stereo loop output enables multi-zone daisy-chaining.
