CTs 4200USP/CN
CTs 8200USP/CN
CTs SERIES
The Crown® CTs 4200USP/CN and CTs
8200USP/CN power amplifiers have an
integrated 3rd generation, DSP-based
PIP™ (Programmable Input Processor) input
module. It connects the amplifier to a 100
Mbps Ethernet network allowing it to be
remotely controlled and monitored via System
Architect™ software. In addition, the input
module allows the transport of real-time digital
audio via CobraNet™ over the same Ethernet
network.
The CTs 4200USP/CN and CTs 8200USP/CN
amplifiers connect to a HiQnet™ audio con-
trol/monitor network using standard 100
Mbps Ethernet hardware (switches, Network
Interface Cards, and cables). CobraNet™ audio
is available over the same 100 Mbps Ethernet
network, providing a simple-to-install, single-
plug solution for audio distribution, control,
and monitoring.
The input module’s SHARC DSP processors
give the user an enormous amount of digital
signal processing. Audio routing, faders,
meters, polarity & mute, input compressors,
filters, delays, multimode output limiters, error
reporting, and load monitoring are all avail-
able. A built in noise generator and sine-wave
generator provide noise masking and test
capabilities. The enhanced AUX port capability
allows the user to interface with the amplifier
to provide external manual control and moni-
toring.
These amplifiers require Harman Pro System
Architect software available from www.crown-
audio/forums.

Input Module Specifications
Connectors:
AUX Connector
Configurable for AUX input, AUX output and
Listen Bus. Listen Bus is also supported
through CobraNet.
Network Connector
The dual RJ45 CobraNet connectors allow a
Primary & Secondary connection to the 100Mb
Ethernet network. Should the Primary connec-
tion lose link activity with the network, the input
module will automatically switch to the Second-
ary connection to ensure uninterrupted audio
and control. The indicators on the RJ45 con-
nectors display network information concerning
the Ethernet and CobraNet connections.
Indicators:
Preset Indicator
Signals the number of the current preset, if
active, by flashing a series of flashes equal to
the current preset number.
IQ Data Indicator
Flashes when the module receives a valid
command that is addressed to the CTs 4200
USP/CN and CTs 8200USP/CN.
Switches:
Reset/Preset Switch
Used to change presets, restore settings to
factory default or restore all the presets to
the factory defaults. During operation of the
switch, the Data indicator flashes as an aid to
the user. Accessible with a straightened paper
clip through the rear panel, the switch selects
the next user preset if pressed for less than
2 seconds, resets the module to preset “0” if
pressed for more than 2 seconds.

for backup of run-time parameters, presets, and
program storage.

Crown’s Three-Year, No-Fault, Fully Transferable Warranty
Crown offers a Three-Year, No-Fault, Fully Transferable Warranty for every new Crown amplifier—
an unsurpassed industry standard. With this unprecedented No-Fault protection, your new Crown
amplifier is warranted to meet or exceed original specifications for the first three years of owner-
ship. During this time, if your unit fails, or does not perform to original specifications, it will be
repaired or replaced at our expense. About the only things not covered by this warranty are those
losses normally covered by insurance and those cuased by intentional abuse. And the coverage is
transferable, should you sell your amplifier.
See your authorized Crown dealer for full warranty disclosure and details. For customers outside
of the USA, please contact your authorized Crown distributor for warranty information or call
574-294-8200.
