CTs Multi-Channel Power Amplifiers
Operation Manual
1 Welcome
Building on the foundation of the Com-Tech ®
Series, Crown’s CTs Series offers new flexibility
and value for installed sound applications. The
Com-Tech Series were the first to offer inde-
pendent 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.
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
• New Crown ® Switching Power Supply for
reduced weight.
• High power-density, with eight channels in
a 3U chassis and four channels in a 2U
chassis.
• Selectable constant-voltage (70V/100V) or
low-impedance (8/4 ohm) operation for
each channel pair.
• FIT (Fault Isolation Topology) circuitry
isolates faults within affected channels.
• 35 Hz High-Pass Filter (70 Hz in CTs
4200) is automatically inserted when the
channel pair is set for constant-voltage
operation. (corner frequency may be
changed as a service option).
• Accepts new MC accessory modules that
tailor the amplifier to suit specific applica-
tions. Modules available for remote VCA
level control and IQ System
® Control.
• Comprehensive array of indicators includ-
ing Power and Data, along with Bridge,
Ready, Signal, Clip, Thermal and Fault for
each channel, provide accurate diagnos-
tics.
• Blue Power Indicator flashes if the ampli-
fier shuts off due to an under-/over-voltage
condition on the AC mains.
• Advanced protection circuitry guards
against: shorted outputs, open circuits,
DC, mismatched loads, general overheat-
ing, under-/over-voltage, high-frequency
overloads and internal faults.
• Proven Crown AB+B Multi-Mode ® output
topology.
• Continuously-variable-speed fans opti-
mize cooling efficiency.
• Three Year, No-Fault, Fully-Transferable
Warranty completely protects your invest-
ment and guarantees its specifications.
