Niles Audio MRZ-6 - Manual (Page 15)

IR Connections for a System with a Dual Zone Receiver and a single MRZ-6
As explained on page 6, a dual zone receiver can be used to independently control source selection for both a home
theater and a multi-room sound system with a MRZ-6. See Figure 18.
• 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 Preamp/Receiver’s front panel.
The IRP unit’s DATA OUT is connected to the MRZ-6’s DATA IN jack to enable control of the sources shared
by both the home theater and the multi-room sound system via the MRZ-6’s repeater system.
• Both ZONE DIP switches should be set to the DOWN (or multi-zone) position. In this position, IR com-
mands passed from other MRZ-6’s (or in this case, commands received from the home theater’s IR main sys-
tem unit and received at the MRZ-6’s IR DATA IN jack) will not be routed to the Dedicated flasher. This
enables the same codes to be used for the main and second zones independent of each other, while the
commands used to control the shared source components are output via the MRZ-6’s Common flasher out-
puts.
