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.
• Four- and eight-channel versions available, each rated @
200 watts per channel @ 8 ohms or 70 volts (100-volts
isolated outputs with optional accessories).
• Individual channels may be selected as low impedance or
70 volt
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.
• Tour Class® protection
• Front and rear panel indicators for amplifier status
• Variable-speed fan
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.
• Sequential turn-on standard
• Euro-style input connectors
• Barrier strip output connectors
• One controlled-voltage input per channel standard
• One fault relay per channel standard
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.
• Module bay provided to input Nx module bay accessories
for full amplifier control and monitoring via NexSys® 4
software or MediaMatrix® product and digital audio
distribution
• 100- and 50-volt operation supported with external
accessories
• EN60849 and ANSI60849 compliant with optional
accessories
