Overview

The AMR-220 is a compact-size Class-D digital mixer/amplifier for classroom or meeting room applications requiring switching of two audio sources (e.g., laptops, video conference systems). Additionally, a microphone can be mixed with the line-level audio sources. The adjustable balanced/unbalanced microphone input supports condenser, dynamic, or wireless microphones.

The loop output can be used to share the same audio sources with multiple AMR-220s that power more speakers in different audio zones. The AMR-220 offers various control options, including IR and RS-232, as well as a convenient top control panel.

  • Two input, one output audio mixer/amplifier.

  • Audio loop output to share audio sources with multiple amplifiers.
