Front Panel Controls and Indicators
Power Switch: Push-on / push-off switch.
Indicators: Bridge Mode, Ready, Signal, Clip,
Thermal, Fault, Data, Power.
Back Panel Controls and Connectors
Power Cord Connector: Standard 15 amp IEC inlet.
Voltage is indicated above IEC inlet.
Reset Switch: Resets the circuit breaker that pro-
tects the power supply.
Speaker Connectors: One four-pole touch-proof
terminal strip. Accepts up to 10 AWG terminal
forks.
Input Connectors: Balanced 3-pin terminal block
connectors, one per channel, on the standard PIP2-
BBY module.
Channel Level Control: One 21-position detented
rotary attenuator per channel, ranging from minus
infinity (–70 dB) to 0 dB gain.
Mode Switch: Two-position switch is used to select
the amplifier’s mode of operation: Dual or Bridge-
Mono.
Highpass Filter: One 3-position switch per channel
selects between OFF, 35 Hz and 70 Hz 3rd-order
filters.
“Y” Input Switch: When set to ON, this switch par-
allels 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.
Ventilation Grille: Front-to-rear forced airflow.
Protection
CTs Series amplifiers provide extensive protection
and diagnostic capabilities, including Thermal Level
Control (TLC), fault, low-pass filters, high-pass
filters, AC under/over voltage protection, DC output
servo, circuit breaker, in-rush 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.

C
rown’s CTs Series amplifiers provide exceptional performance, flexibility and value for installed
sound applications. CTs Series amplifiers feature independent selection of high and low impedance
operation for a specific channel, plus power levels and features that were carefully chosen to match
the requirements of fixed install design. Easy integration with HiQnet™ and CobraNet™ allows CTs
amplifiers to deliver a comprehensive lineup of monitoring and control features along with digital audio
transport for an award-winning digital audio solution.
