Module Bay; Module Removal - Crest Audio CKd 604 Owner's Manual

CKd Owner's Manual
preventing sudden bursts of audio from arriving at the amplifier's output after its
output relays initially close.
NexSys Fault Monitoring
A CKd equipped with an NxDante8 or NxCobraNet8 module and connected to a
NexSys network will report fault conditions to the PC controlling the network. If a
networked amplifier enters ACL or IGM or experiences a thermal, DC voltage, or
short circuit fault, the fault condition will be reported the PC interface. This allows
easy monitoring of amplifier operating conditions across a large or widespread
network from a single location.

Module Bay

CKd Power Processing amplifiers come standard with a blanking panel fixed over
the module bay. When a NexSys module is installed in this bay, connection to a
network is made via a standard RJ-45 connector and CAT-5 Ethernet cable.

Module Removal

Only 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.
Note: Removable modules contain static-sensitive devices; handle modules
only at static-safe workstations!
Replacing or Installing a Network Module
The amplifier must be switched off and unplugged from the AC mains supply before
this operation is undertaken. Two Phillips head screws secure the module to the
chassis. The module is connected electrically to the amplifier with a single multi-pin
ribbon cable. Once unscrewed from the chassis, unplugging the module from this
ribbon cable frees the module for removal. To insert a module, simply reverse this
procedure.
Note: Standard CKd Power Processing amplifiers come with a blank panel
installed in the Network bay. The amplifier must not be operated without a
Network module or blank panel in place.

NexSys Module Basics and Installation
Although the CKd Power Processing amplifiers are venerable audio workhorses in
their own right, the true breadth of their capabilities is only reached once they are
tied into a NexSys amplifier network. In order for a CKd to capitalize on this network
potential, it must be equipped with one or more of a series of NexSys modules.
These modules reside in the CKd's module bay (see Amplifier Layout for the exact
location of the module bay) and provide numerous control, monitoring, and signal
processing features to the NexSys system. This section will cover installation
NexSys modules as well as important information concerning computer control of a
NexSys system.
Overview
The extended capabilities of CKd amplifiers are reached when connected to a
NexSys amplifier network via a NexSys module. These modules reside in the CKd's
module bay and provide control, monitoring, and signal processing features. This
section covers the installation of NexSys modules as well as information concerning
computer control of a NexSys system.
