Description
Designed for speech reinforcement in classrooms, conference rooms, and other small- to medium-size venues, the KD-AMP220 from Key Digital is a 2-channel Class-D compact digital audio amplifier capable of delivering 20W per channel at 4 Ohms or 40W at 8 Ohms in bridged mode. The amp has a microphone input that allows you to provide phantom power to a condenser microphone. There are two analog inputs to choose from, a 6-pin terminal block and a 3.5mm stereo port. The output is a mix of the microphone and the selected audio input. In addition to the front-panel controls, the KD-AMP220 offers control via RS-232 or IR for integration with your professional AV control system.
