RTI CP-1650 16 Channel Cool Power Amplifier

(No reviews yet) Write a Review

Utilizing Cool Power technology to expand the capabilities of an AD-8 audio distribution system, the CP-1650 is perfect in residential and commercial installations where larger rooms need more speakers and areas such as an outdoor patio need to be added to an existing zone. Designed to be an easy and cost effective way to double the power of the AD-8 output, having the additional 50 watts per channel solves those installation puzzles. If the power needs even more boost, you can bridge two channels with a simple flip of a switch, for a whopping 100 watts per channel.


The CP-1650 is designed to offer greater flexibility, especially in larger installations. Unique features, including looped audio outputs, a 12VDC trigger out and IR passthrough, make it easy to daisy chain mulitiple units together. Input level adjustments provide a tremendous amount of control over the audio in each room, keeping the big rooms full of sound and the smaller rooms from blaring. Discrete power control options include IR, two-way RS-232 or a voltage trigger input.
