CTs 2-Channel Power Amplifiers
Operation Manual
1 Welcome
Building on the foundation of the Com-Tech®
Series, the Crown®CTs Series offers new flexi-
bility and value for installed sound. The Com-
Tech Series was the first to offer independent
selection of high- and low-impedance opera-
tion 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
• Switching Power Supply for reduced
weight.
• High power-density, with all two-channel
models in a 2U chassis.
• Direct constant-voltage
(70V/100V/140V/200V) or low-impedance
(2/4/8 ohm) operation. No switch
required.
• Input sensitivity is independently select-
able for each channel. Choose low-imped-
ance (4/8 ohm), constant-voltage (70V/
100V/140V/200V), or 26 dB.
• TLC protection circuitry protects the
amplifier from long-term excessive heat by
subtly and dynamically reducing the gain
only when necessary.
• JTS circuitry (CTs 600/1200 only) quickly
protects BJT output transistors from
unsafe operating conditions without shut-
ting the channel down. (Not applicable to
BCA amplifiers as they are inherently pro-
tected.)
•PIP2™ (Programmable Input Processor)
connector accepts accessory modules that
tailor the amplifier to suit specific applica-
tions.
• Removable terminal block input connec-
tors, with “Y” Input Switch in the standard
PIP2-BBY module.
