Matrix™ 120 Receiver Amplifier

PN: IMA-120

Amplifier | Infrared Microphone Receiver | Audio Mixer | Wall Panel Controller

The Matrix™ is ideal for plenum applications of the Sound Field amplifier/receiver. With a simple CAT5 cable, the TeachLogic CPS-120 (or CPR-125) wall mount controller manages audio sources connected to the amplifier.

The controller has an intuitive touch interface with the additional benefit of Bluetooth® pairing of an extra audio device (such as a amartphone). And with two infrared wireless microphone channels, the Matrix™ is sure to be the low profile, high feature Sound Field solution you’ve been looking for.
