uilding on the foundation of the Com-Tech
®
 
Series, Crown’s CTs Series offers new fl ex-
ibility and value for installed sound applica-
tions. The Com-Tech Series were the fi rst to offer 
independent selection of high- and low-impedance 
operation 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. 
For added fl exibility, the CTs Series includes both 
dual-channel and multi-channel models.
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.
The CTs multi-channel amps feature FIT (Fault Iso-
lation Topology), which isolates channel-specifi c 
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.
In a profession where unplanned service calls 
quickly wipe out profi ts, the CTs Series amplifi ers 
are designed to be the most reliable amplifi ers you 
can install.

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.
•  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).
•  FIT (Fault Isolation Topology) circuitry isolates 
faults within affected channels.
•  TLC protection circuitry protects the amplifi er 
from excessive heat by subtly and dynamically 
reducing the gain only when necessary to 
reduce heat levels.
•  Accepts new MC accessory modules that tailor 
the amplifi er to suit specifi c applications. Mod-
ules available for remote VCA level control and 
IQ System
®
 Control. 
•  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).
•  Comprehensive array of indicators including 
Power and Data, along with Bridge, Ready, 
Signal, Clip, Thermal and Fault for each chan-
nel, provide accurate diagnostics.
•  Blue Power Indicator fl ashes if the amplifi er 
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 overheating, under-/over-volt-
age, high-frequency overloads and internal 
faults.
•  Proven Crown AB+B Multi-Mode
®
 output topol-
ogy.
•  Continuously-variable fans optimize cooling effi -
ciency.
•  Three Year, No-Fault, Fully Transferable 
Warranty completely protects your investment 
and guarantees its specifi cations.
•  Crown’s advance-replacement Profi t 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.
