NOTE:
Each CNX-PAD8A is capable of distributing audio to eight rooms,
maximum. It is possible to expand distribution to more rooms, if additional
CNX-PAD8As are introduced into the system. Crestron recommends a maximum of
four CNX-PAD8As per system. Therefore, audio can be distributed to a maximum of
32 rooms. Each input source has two sets (left and right) of RCA jacks connected in
parallel. Use one set of the jacks for source input and the other set for loop-through.
Network Wiring
NOTE:
When making wire connections, refer to the latest revision of the Cresnet
Network Interconnect Drawing (Doc. 5411). The document can be obtained from the
Downloads page (CABLES and MANUAL Libraries) of the Crestron website (www.
crestron.com). Search for the CRESNET.PDF files.
When calculating the wire gauge for a particular network run, the length of the run
and the power factor of each network unit to be connected must be taken into
consideration. If network units are to be daisy-chained on the run, the power factor
of each network unit to be daisy-chained must be added together to determine the
power factor of the entire chain. The length of the run in feet and the power factor of
the run should be used in the following resistance equation to calculate the value on
the right side of the equation.
