1 Welcome

Building on the foundation of the Com-Tech
®
Series, the Crown CTs Series offers new
®
fl exi bility and value for installed sound. The
Com-Tech Series was the fi rst to offer
independent selection of high- and low-
impedance opera tion for a specifi c channel, and
CTs Series amplifi ers continue that tradition,
with power levels and features carefully chosen
to perfectly integrate into fi xed install design
requirements.
Modern power amplifi ers 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 amplifi ers 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 amplifi er.

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/140V) 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
amplifi er 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
amplifi ers as they are inherently pro tected.)
• P I P2™ (Programmable Input Processor)
connector accepts accessory modules that
tailor the amplifi er to suit specifi c
applica tions.
• Removable terminal block input
connec tors, with "Y" Input Switch in the
standard PIP2-BBY module.
