Expansion Connection

This RJ-45 port connects the two ZR-4 MultiZone Receivers with CAT-5 cable using the T568A wiring convention. One ZR-4 MultiZone Receiver will be configured to be the Master, the other to be the Slave.

Source Components

The audio output of the source components must be routed to both the Master and Slave MultiZone Receivers. This is best accomplished using a Niles AVDA-3 Source Level Stereo Audio/Video Distribution Amplifier (FG00814) for each source. A second but less effective method would be to use RCA Y-adaptors to split the source component outputs in two, one going to the Master chassis, the other to the Slave chassis.

source component control

All MicroFlashers for source component control must connect to the Master and not the Slave. IR from the Keypads connected to the Slave chassis will be routed to the Master chassis via the expansion connection port.

Keypads

Keypads for the additional zones are connected to the Slave chassis Keypad ports. These Keypads connect to the Slave ZR-4 by a “home run” of CAT-5 cable with RJ-45 connectors utilizing the T568A wiring convention.

Loudspeakers

Each additional zone has “home run” speaker cables from the Slave Niles ZR-4 MultiZone Receiver to the location of the speakers. Connections are made utilizing removable speaker terminals. These terminals accept speaker wire up to 16 AWG in size.

External Control

All external IR or RS-232C control must be made to the Master only, and not to the Slave. The commands necessary to control the Slave will be relayed through the expansion connection.
