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-andtrue modular approach to intelligent amplifier configuration. Through the provision of a single module bay, these amplifiers comes with a module that facilitates 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.
