CTs Series
Multi-channel
uilding on the foundation of the Com-Tech®
Series, Crown’s CTs Series offers new flex-
Bibility 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.
For added flexibility, the CTs Series includes both
dual-channel and multi-channel models.
•
Comprehensive array of indicators including
Power and Data, along with Bridge, Ready,
Signal, Clip, Thermal and Fault for each chan-
nel, provide accurate diagnostics.
Features
•
New Crown Switching Power Supply for
reduced weight.
•
High power-density, with four channels (CTs
4200) or eight channels (CTs 8200) in a 3U
chassis.
•
•
Blue Power Indicator flashes if the amplifier
shuts off due to an under/over voltage condition
on the AC mains.
•
Selectable constant-voltage (70V/100V) or
low-impedance (4/8 ohm) operation for each
channel pair. (Channel pair must be operated
in Bridge mode for 100V output).
Advanced protection circuitry guards against:
shorted outputs, open circuits, DC, mismatched
loads, general overheating, under-/over-volt-
age, high-frequency overloads and internal
faults.
Proven Crown AB+B Multi-Mode® output topol-
ogy.
All models in the CTs Series feature Crown’s new
Switching Power Supply for lighter weight, and all
models are also compatible with the IQ System®.
Multi-channel models accept new MC accessory
modules that provide enhanced control, monitor-
ing, and system integration.
•
•
FIT (Fault Isolation Topology) circuitry isolates
faults within affected channels.
•
•
•
TLC protection circuitry protects the amplifier
from excessive heat by subtly and dynamically
reducing the gain only when necessary to
reduce heat levels.
The CTs multi-channel amps feature FIT (Fault Iso-
lation Topology), which isolates channel-specific
faults and prevents them from affecting remaining
channels. If a CTs multi-channel amp is powering
multiple zones, and a channel fails, the other zones
continue to operate.
Continuously-variable fans optimize cooling effi-
ciency.
Three Year, No-Fault, Fully Transferable
Warranty completely protects your investment
and guarantees its specifications.
•
•
Accepts new MC accessory modules that tailor
the amplifier to suit specific applications. Mod-
ules available for remote VCA level control and
IQ System® Control.
In a profession where unplanned service calls
quickly wipe out profits, the CTs Series amplifiers
are designed to be the most reliable amplifiers you
can install.
•
Crown’s advance-replacement Profit Protec-
tion Plan provides quick, no-questions-asked
replacement of covered amps should they fail
at any time up to 6 months following date of
installation.
35-Hz High-Pass Filter is automatically
inserted when the channel pair is set for con-
stant-voltage operation (corner frequency may
be changed as a service option).
