User manual CREST AUDIO CK MODULE

[. . . ] Parameters can also be created ahead of time without any modules attached, stored in the N-Coder, then downloaded into the module's memory later. Except for DSP modules, all NC Input Processing modules can be programmed from an N-Coder. Programming with N-Coder/PC software N-Coder/PC Software, a Windows®-based program that configures all Input Processor NC modules, will run on any PC with Windows `95 or 3. 1. The computer's parallel (printer) port is used with a DB25 to RJ-14 adapter and cable (both supplied) that connects to the Input Processor NC module. [. . . ] These internal jumpers (two for CC-IPB, three for all input NC modules), labeled "W1 W2 W3", are used to set the overall gain of the amplifier.

All jumpers 0dBu +32dB must be set to the same position as X40 (+32dB) Standard Factory Setting shown. To change jumper settings, the Input module must first be removed from the amplifier. CREST AUDIO 26C2197-02 W1 W2 A B Warning!Amplifier must be removed from AC mains supply before this operation is undertaken!The diagram at left shows the location of these jumpers on the CC-IPB module. The diagram at the lower right shows the location of the jumpers on the NC-IPN module. Input Gain/Sensitivity Jumpers NexSys/N-Coder jumper All NC Modules have internal jumpers used to set the module for operation with NexSys or NCoder. These jumpers are labeled "W4 W5" on the Input module circuit board.

W4 W5 Note: Factory setting is the `NexSys' position. If NexSys, N-Coder, or N-Coder/PC software is not being used, jumper position will have no effect upon the operation of the amplifier. Swapping out Modules Only jumper setting changes or module upgrades require modules to be removed from the amplifier. Contact Crest Audio Customer Service for full details on module removal. The `General Module Setup' diagram indicates the general setup of the rear panel module/bay configuration. Should the module jumpers need to be changed or removed, a pair of long nose or needle nose pliers is also useful. Precautions Amplifier is shown with the top cut away for clarity only. Dangerous voltages exist inside, and only a Crest Audio-certified service technician should remove the top cover!Removable modules contain staticsensitive devices; handle modules at static-safe work stations!The amplifier MUST be switched off and the mains plug removed from the supply before module removal operation is undertaken. If Load Monitoring is employed, an additional ribbon cable will be located here. Network Module Input Module Designed & manufactured in the USA by: Crest Audio Inc.

Remove the four #8 3/8" Phillips pan head sheet metal screws that secure the module to the chassis. The module is connected electrically to the amplifier via multi-pin ribbon cables. Unplugging the module from the ribbon cable connectors frees the module for removal. To insert the same or another module, simply reverse this procedure, making sure that any ribbon cable connectors are properly and securely seated. Note: The amplifier must not be operated without an Input module in place. 6 DCBA CLASS 2 WIRING MAY BE USED Output ­ A N-Coder Data Port Error + PUSH + B ­ Signal Ground Lift Jumper Designed & manufactured in the USA by: Model Name CKV 100 CKV 200 CKV 400 CKV 800 CKV 1600 CKV 2400 Network Data 5432 6 5432 6 +­ +­ Hi DO NOT attempt to replace or remove a Power/Output Module.

[. . . ] Note: when using NexSys control, hard-wiring for manual switch closure between amplifiers should be used cautiously. If the switch closure output is wired up, it WILL cause the next amp to switch, regardless of which source (hardware switch or NexSys STO) has initiated the command. The modules (and the non-NexSys compatible CC-SIO) feature a 6-pin connector providing a 3wire input from switch closures (or from a CK family amplifier) and an opto-isolated 3-wire output to another CK amplifier. To initiate either the ON or OFF function manually, simply provide a closure from the proper signal line to COM; after a time delay of approximately 200ms, the closure is echoed on the 3 isolated output signal pins to initiate the turn-on function in `downstream' amplifiers.
