NexSys v. 3.0 Crest Audio Inc.
Pro class network setup diagram
The diagram above shows one Supervisor mainframe with three Professional Series ampli-
fiers connected, one Load Monitor mainframe, and one CKS amplifier.
Each Supervisor main frame can accept up to 24 dual channel amplifiers. An amplifier
attached to a Supervisor uses the Supervisor’s address (primary) and its Supervisor port
number to specify its secondary address. NexSys would report addresses for the Devices in
this figure as follows:
Device Address
8001 1,1
7001 1,2
6001 1,24
The only time a Supervisor will appear in the software is when the system is being polled
during AutoPlan. NexSys does not need to identify the Supervisor as such; its presence is
indicated inherently by the amplifiers attached to it -- you can't "control" or monitor a
Supervisor, you can control and monitor the amplifiers.
Load Monitor Mainframe (Pro Class only)
The Load Monitor is similar to a Supervisor in its transparent nature to the software. You
specify that an amplifier's outputs are connected to the channels of a Load Monitor in the
amplifier setup dialog. The setup dialogue for the amp labeled "Pro Series 8001" would look
like this for channel A:
