Input module on back panel
he Crown® CTs 4200USP/CN and CTs T8200USP/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 control/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, singleplug 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 available. 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 monitoring.
These amplifiers require Harman Pro System Architect software available from www.crownaudio/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 connection lose link activity with the network, the input module will automatically switch to the Secondary connection to ensure uninterrupted audio and control. The indicators on the RJ45 connectors 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.
General:
