Matrix™ Receiver Amplifier Description

Print Friendly, PDF & Email

The Matrix™ is ideal for any room where the amplifier needs to be out of sight and/or in a vault for security. It connects to the same ceiling sensor and speakers as our other user-friendly systems.

With a simple CAT-5 cable, the TeachLogic CPS-121 (or CPR-125) wall controller manages the audio sources and volume levels so that the amplifier can be installed somewhere secure.

The controller has an intuitive touch interface with the additional benefits of Bluetooth and an additional 3.5 mm input. When combined with up to 2 wireless microphones and four (8-ohm) overhead speakers, the Matrix™ is more than just a sound system…it creates a true “Sound Field” in the classroom so every student hears all audio sources equally well.

Why IR?
