Network Bay.

Network Module Controls/Connections.

CK Power Processing amplifiers come standard with a blanking panel fixed over the Network bay. When a Network module is installed in this bay, network connection is made via a pair of three- pin connectors. They are wired in parallel, and form a loop-through connection. (Mates for these connectors are shipped with the Network module.) Network bus addressing is accomplished through use of the Hi and Lo Address dials. Refer to module documentation for exact connection and control information.

Power/Output Module Connections.

Speakers are connected using the Output Barrier Strip connectors. Spade lugs, ring tongues or bare wire may be connected to the output barrier strip elements. Spade Lug measurements for Output barrier strip are as follows: .44" (11mm) screw spacing, .32" (8mm) lug space. For output spade lugs, Panduit Part No. PNF 14-8LF-C (or equivalent) is recommended. (Consult the wire gauge charts in theis manual for speaker wiring recommendations.) Make sure the ampli- fier is turned off before you change any output connections or jumpers. Also ensure that the load impedance being connected is not less than the amplifier's ability to drive it.

On the standard CC-STL Power/Output module, a four-pin Sequential Turn-On/Turn-Off (STO) connector is suppled. A mating connector is shipped with the amplifier. For more information on STO, see the section on Sequential Turn-On/Off.

Module Removal.

Removable modules contain static-sensitive devices; handle modules at static-safe work stations!

Situations Requiring Module Removal

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.

If Load Monitoring is employed, an additional ribbon cable will be located here.

General Module Setup Diagram.	Input Module

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 top cover !

The amplifier must be switched off and the mains plug removed from the supply before module removal operation is undertaken.

Removing or Replacing an Input Module.

The amplifier must be switched off and unplugged from the mains supply before this operation is undertaken. 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.
