he Crown® CTs 4200USP/CN and CTs T8200USP/CN power ampliﬁers have an

Input Module Features (For ampliﬁer features, see the CTs multichannel ampliﬁer datasheet.)

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.

•100 Mbps Ethernet single-plug solution for CobraNet audio, and HiQnet control and moni- toring

•Analog audio inputs allow CobraNet network audio input, CobraNet audio backup, or a hard- wire emergency override of CobraNet audio

•24 bit digital to analog conversion with 32 bit, ﬂoating point DSP processing

•Up to 18 assignable ﬁlters per channel with 9 different ﬁlter types including all-pass ﬁlters

•Over 2 seconds of delay available per channel

•Input compressors and output limiters for each channel

•Dual, uncorrelated noise generators for noise masking

•Sine generator

•Load supervision

•Full error reporting

•Firmware upgrades via the network

•10 user selectable presets

•Reliable FLASH memory backup of all parameters

•Three Year, No-Fault, Fully Transferable Warranty completely protects your invest- ment and guarantees its speciﬁcations

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.

General:

Memory Backup: Non-volatile FLASH memories for backup of run-time parameters, presets, and program storage.

Communications: 100Mb Fast Ethernet con- forming to IEEE 802.3.
