Input Module Specifi cations
The Input Module shall meet the following specifi cations:
AUX Connector: Confi gurable 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 automat-
ically 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.
Preset Indicator: Signals the number of the current preset, if active, by fl ash-
ing a series of fl ashes 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. Reset/Preset Switch: Used to
change presets, restore settings to factory default or restore all the presets
to the factory defaults. During operations of the switch, the Data indica-
tor fl ashes as an aid to the user. Accessible with a straightened paper clip
through the rear panel, selects the next user preset if pressed for less than
2 seconds, resets the module to preset “0” if pressed for more than 2 sec-
onds. Memory Backup: Non-volatile FLASH memories for backup of run-
time parameters, presets, and program storage. Communications: 100Mb
Fast Ethernet conforming to IEEE 802.3.
Overall Audio Performance: DSP Processing: Two processors, 32 bit, Float-
ing Point, 724 µs latency. D/A and A/D Conversion: 24 bit. Latency:
DSP processing: 1 ms or 1000 µs, Analog-to-digital conversion: 250 µs,
Digital-to-analog conversion: 250 µs, Amplifi er: 100 µs, Total: 1.6 ms or
1000 µs. Range: 103 dB typical (A-weighted, 20Hz–20kHz, audio sourced
from muted CobraNet channel) Distortion: < 0.1% THD+N, 20Hz–20kHz.
Frequency Response: ± 0.5 dB, 20Hz–20kHz. Input/Output Monitor Accu-
racy: Typically ±1dB. Maximum Input Level: + 20 dBu.
The amplifi er shall be designated the Crown CTs 4200 USP/CN.
