CTs Series Multi-channel

uilding on the foundation of the Com-Tech®BSeries, Crown’s CTs Series offers new flex- ibility and value for installed sound applica- tions. The Com-Tech Series were the first to offer

independent selection of high- and low-impedance operation for a specific channel, and CTs Series amplifiers continue that tradition, with power levels and features carefully chosen to perfectly integrate into fixed install design requirements. For added flexibility, the CTs Series includes both dual-channel and multi-channel models.

All models in the CTs Series feature Crown’s new Switching Power Supply for lighter weight, and all models are also compatible with the IQ System®. Multi-channel models accept new MC accessory modules that provide enhanced control, monitor- ing, and system integration.

The CTs multi-channel amps feature FIT (Fault Iso- lation Topology), which isolates channel-specific faults and prevents them from affecting remaining channels. If a CTs multi-channel amp is powering multiple zones, and a channel fails, the other zones continue to operate.

In a profession where unplanned service calls quickly wipe out profits, the CTs Series amplifiers are designed to be the most reliable amplifiers you can install.
