uilding on the foundation of the Crown

Com-Tech

Series, the CTs Series offers new

fl exibility and value for installed sound appli-

cations. The Com-Tech Series was 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 Harman Pro
System Architect as well as the IQ System

Two-channel models accept PIP2™ modules, and
also feature selectable high-pass fi lters and input
sensitivity for each channel.

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

•

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

•

Input sensitivity independently selectable for each
channel

•

TLC protection circuitry protects the amplifi er from
long-term excessive heat by subtly and dynamically
reducing the gain only when necessary

•

PIP2 (Programmable Input Processor) connector
accepts accessory modules that tailor the amplifi er
to suit specifi c applications

•

Removable terminal block input connectors, with “Y”
Input Switch in the standard PIP2-BBY module

• Switchable high-pass fi lter for each channel provides

low-frequency roll off to eliminate step down trans-
former saturation when used in distributed systems

• Comprehensive array of indicators including Power,

Data and Bridge, along with Ready, Signal, Clip,
Thermal and Fault for each channel, provide accurate
diagnostics

• Blue Power Indicator fl ashes if the AC mains is

under/over voltage

• Advanced protection circuitry guards against: shorted

outputs, DC, mismatched loads, general overheating,
under/over voltage, high-frequency overloads and
internal faults

• JTs circuitry (CTs 600/1200) quickly protects output

transistors from unsafe operating conditions without
shutting the channel down

• Legendary Crown AB+B (Multi-Mode

) output

topology in the CTs 600/1200 and Class I (BCA

)

output topology in the CTs 2000/3000 offer the best
in amplifi er reliability

• Continuously variable fans optimize cooling effi ciency

• Three Year, No-Fault, Fully Transferable

Warranty completely protects your investment and
guarantees its specifi cations
