IR Connections for a System with a Dual Zone Receiver and up to six MRZ-6’s

This system is very similar to the dual zone/single MRZ-6 system. The dual zone receiver may be used to indepen-
dently control source selection for both a home theater and a multi-room sound system of up to 36 rooms with six
MRZ-6’s. See Figure 19.

• It is not necessary to sync the Preamp/Receiver if the second zone has dedicated "on" and "off" commands

or can be activated with an input select command. Note: If the dual zone receiver you are using has a con-
trol voltage output or a switched outlet which is active ONLY when the second zone is on, the second zone
may be synced. However, if the second zone does not have discrete "on" and "off" commands, or the abil-
ity to turn on with an input select command as described above, the receiver cannot be automated.

• If an IR sensor is required to operate the main zone of the home theater, a sensor must be connected to a

Niles IR Main System Unit with a flasher to control the main zone via the receiver’s front panel. The IRP
Main System Unit’s DATA OUT is connected to the Slave MRZ-6’s DATA IN jack to enable control of the
sources shared by both the home theater and the multiroom system via the MRZ-6’s repeater system.

• Both ZONE DIP switches on both MRZ-6’s should be set to the DOWN (or multi-zone) position. In this con-

figuration, IR commands issued from the home theater will not be routed to either MRZ-6’s Dedicated flash-
er. This enables identical Preamp/Receiver commands to be used for both the home theater and the multi-
room sound systems independently, while the commands used to control the shared sources are output via
the Master MRZ-6’s Common flasher outputs.

• The DATA OUT of the Slave MRZ-6’s is connected to the Master MRZ-6 via the DATA IN and DATA OUT

jacks. See Figure 15.

• The UART connection enables the Slave MRZ-6’s to power on the Preamp/Receiver using the automation

codes taught to the Master MRZ-6. The UART connection also enables All On and All Off control of all the
rooms in the system. See page 20 of the MRZ-6 manual.

• If IntelliPads or IR sensors are used with or without RP-9 keypads, the Master and all additional Slave MRZ-

6’s Dedicated flasher outputs must be tied together to enable access to the receiver’s second zone IR input.
Note: It is not necessary to diode isolate the MRZ-6’s Dedicated flasher outputs.

For more information concerning IntelliPad®/MRZ-6 programming, see page 26 of the MRZ-6 manual.
