Details
The Ci™ Series amplifiers are designed to drive low-impedance or 70V speaker loads without bridging between channels. Bridged operations are supported for additional power into 8 ohm loads or 140V 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 come 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.- Features
