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.
