CONFIGURATION 2 – ADDING ZONES USING MULTIPLE ZR-4630’S
More than one ZR-4630 can be used if the system requires more than six zones. A maximum of three ZR-4630’s,
providing up to 18 zones, can be combined to create a larger multi-zone/multi-source system. One ZR-4630 is
designated as the Master and the others as Slaves (see Installation Settings on page 58 for more details).
As shown in Figure 5, a four-pair twisted cable connecting the expansion ports of the two ZR-4630’s facilitates
communication between them. This communication enables all zones provided byboth ZR-4630’sto obtain
control of the shared-source components (which are always connected to the Master). Also, system-wide
commands can be issued from any zone (i.e. All Zones ON/OFF).
Sharing Source Components with Two ZR-4630’s
The Niles ZR-4630 MultiZone Receivers (Figure 5) share the audio signal from the source components via RCA
Y-adapters. Audio signals are connected to both ZR-4630’s.
Note: When sharing source components with a third ZR-4630 (for an 18-zone system) or with a Home Theater
system, refer to Configuration 3.
Source-component control (Figure 6) is accomplished via the programming in the master ZR-4630. All Slave
ZR-4630’s in the system must be left unprogrammed except for tuner preset stations. All Flasher and Sync Input
connections for the shared source components are made to the Master ZR-4630. Keypad/Source Button
commands and zone On/Off status are communicated to the Master ZR-4630 using the System Expansion
In/Out connections, providing coordinated control of all source-components.
