DESCRIPTION:

The Ci Series is the next generation family of elevated efficiency

amplification from Crest Audio. Ci amplifiers are designed to

drive low-impedance or 70-volt speaker loads without bridging

between channels. Bridged operations are supported for

additional power into 8-ohm loads or 140-volt operation.

As with all Crest Audio products, sonic performance is of

primary importance. In addition, high-efficiency, comprehensive

load protection and compact packaging have been achieved in

the Ci design.

The Ci Series amplifiers incorporate Crest Audio’s tried-and-

true modular approach to intelligent amplifier configuration.

Through the provision of a single module bay, these amplifiers

may accommodate modules that facilitate load monitoring,

digital audio delivery and Crest Audio’s NexSys networking.

A full complement of features and options makes this series

very versatile, whether powering airport systems, restaurant

audio or a myriad of other applications. The Ci Series amplifiers

bring a new generation of amplification to Crest Audio.
