1 Welcome

Building on the foundation of the Com-Tech®Series, Crown’s CTs Series offers new flexibility and value for installed sound applications. The Com-Tech Series were the first to offer inde- pendent 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.

Modern power amplifiers are sophisticated pieces of engineering capable of producing extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable service for which they were designed.

In addition, CTs Series amplifiers include a number of features which require some expla- nation before they can be used to their maxi- mum advantage.

Please take the time to study this manual so that you can obtain the best possible service from your amplifier.

1.1 Features

•New Crown® Switching Power Supply for reduced weight.

•High power-density, with eight channels in a 3U chassis and four channels in a 2U chassis.

•Selectable constant-voltage (70V/100V) or low-impedance (8/4 ohm) operation for each channel pair.

•FIT (Fault Isolation Topology) circuitry isolates faults within affected channels.

•35 Hz High-Pass Filter (70 Hz in CTs 4200) is automatically inserted when the channel pair is set for constant-voltage operation. (corner frequency may be changed as a service option).

•Accepts new MC accessory modules that tailor the amplifier to suit specific applica-

tions. Modules available for remote VCA level control and IQ System® Control.

•Comprehensive array of indicators includ- ing Power and Data, along with Bridge, Ready, Signal, Clip, Thermal and Fault for each channel, provide accurate diagnos- tics.

•Blue Power Indicator flashes if the ampli- fier shuts off due to an under-/over-voltage condition on the AC mains.

•Advanced protection circuitry guards against: shorted outputs, open circuits, DC, mismatched loads, general overheat- ing, under-/over-voltage, high-frequency overloads and internal faults.

•Proven Crown AB+B Multi-Mode®output topology.

•Continuously-variable-speed fans opti- mize cooling efficiency.

•Three Year, No-Fault, Fully-Transferable Warranty completely protects your invest- ment and guarantees its specifications.
