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 mon-
itoring and control features along with digital audio transport for an award-
winning digital audio solution.

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 Controls: 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 ter-
minal strip. Accepts up to 10 AWG terminal forks.
DC Output Offset (shorted input): < 2 millivolts.
Protection
CTs Series amplifiers provide extensive protection
and diagnostic capabilities, including Thermal Level
Control (TLC), fault, low-pass filters, high-pass fil-
ters, 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.
