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.

System Solutions: IQ

PIP™ LITE, IQ-PIP USP3,

IQ-PIP USP3/CN, PIP-3632, PIP-4622, PIP-4632 and

PIP-USL.

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.

CTs 600: 22.8 lbs. (10.3 kg);

CTs 1200: 23.4 lbs. (10.6 kg);

CTs 2000: 27.0 lbs. (12.2 kg).

CTs 3000: 27.7 lbs. (12.6 kg).

Shipping Weight,

CTs 600: 27.7 lbs. (12.6 kg);

and allows other amplifiers without direct constant voltage output to

be easily integrated into distributed systems.

TP-170V: This is a rack-mountable panel with four autoformers as

described above.
