AMR-350 3 x 1 Audio Amplifier
The AMR-350 is a compact-sized Class-D digital amplifier for classroom or meeting room applications requiring switching of three audio sources (e.g., laptops, video conference systems, Blu-ray players).
AMR-350 features two analog audio inputs and one digital optical audio input. The Class-D amplifier powers the connected speakers with 2 x 50 Watts Stereo or 1 x 100 Watts in bridge mode. The loop output can be used to share the same audio sources with multiple AMR-350s that connect more speakers in different audio zones. The AMR-350 can be controlled via RS-232, Ethernet, web interface and the front control panel.
