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.
