5.0 NexSys Module Basics and Installation
Although the Ci 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 Ci 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 Ci’s module bay (see Chapter 3 – Amplifier
Layout for the exact location of the module bay) and provide numerous control,
monitoring, and signal processing features to the NexSys system. This chapter will
cover installation of the three NexSys modules as well as important information
concerning computer control of a NexSys system. For diagrams of the layout
of a particular NexSys module, please see Chapter 6 – NexSys Module Layout.
Instructions for operating a given module can be found in Chapters 7, 8, and 9.
To learn about controlling a system of NexSys amplifiers from a PC GUI, please
reference the NexSys Software Manual included with each NexSys Module and
NexSys equipped amplifier.
Installation
Network Modules
There are two types of modules that allow a Ci amplifier to be wired in to a NexSys
network – the NxEthernet8 Module and NxCobranet8 Module. Although they
have different feature sets, they both serve the networking function in an amplifier.
Because of this, this manual may refer to them collectively as the “network modules.”
The installation procedure for either of these network modules is he same, and is
covered in this section.
1
Begin by removing the blanking panel covering the Ci’s module bay. To do this,
simply unscrew the screws on either side of the panel. Be sure to save these two
screws, as they will be needed for fastening the network module into the module
bay.

2
Prepare to install the 50-pin ribbon cable supplied with the network module.
Peer into the exposed module bay and locate the ribbon cable connector on the
amplifier’s circuit board. Take note of the way the connector is keyed, and orient the
ribbon cable to match the keying of the connector. Insert the cable into the module
bay and press it firmly into the connector on the amplifier, allowing the opposite end
to dangle out of the module bay.
