Building on the foundation of the Com-Tech Series, Crown’s CTs
Series offers new flexibility 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.

Controls and Indicators
Front Panel Indicators: Bridge Mode, Ready, Signal, Clip, Thermal, Fault,
Data, Power.
Back Panel Controls and Connectors
Power Cord Connector: IEC
Reset Switch: Resets the power circuit breaker.
Channel Level C ontrols: 21-position detented, one per channel.
Level Attenuation: Approx. –95 dB to 0 dB gain.
High-Pass Filter: One three-position switch per channel selects between
OFF, 35 Hz and 70 Hz 3rd-order filters.
Mode Switch: Two-position switch is used to select the amplifier’s mode
of operation: Dual or Bridge-Mono.
“Y” Input Swtich: When set to ON, this switch parallels the input signals
of the two channels, for use when the input signal is mono. Also can
be used to daisy-chain the signal to another amplifier.
Input/Output
Input Connectors: Balanced 3-pin terminal block connectors, one per
channel, on the standard PIP2™-BBY module.
Input Impedance: (nominally balanced, nominally unbalanced): 10 k
ohms, 5 k ohms.
Output Connectors: One four-pole touch-proof terminal strip. Accepts up
to 10 AWG terminal forks.
DC Output Offset (shorted input): < 2 millivolts.
Protection
CTs Series amplifiers provide extensive protection and diagnostic capabili-
ties, including Thermal Level Control (TLC), fault, low-pass filters, high-
pass filters, AC under/over voltage protection, DC output servo, circuit
breaker, inrush limiting, and Junction Temperature Simulation (JTS) in
CTs 600/1200.
Construction
Ventilation: Front-to-rear forced airflow. Two continuously variable speed
fans direct the airflow through the amplifier for cooling.
Dimensions: EIA Standard 19-inch (48.3-cm) rack mount width (EIA RS-
310-B), 3.5-inch (8.9-cm) height and 14.25-inch (36.2-cm) depth
behind the mounting surface.
