Niles Audio MRZ-6 - Manual (Page 17)

IR Connections for a System with two or more Preamp/Receivers and MRZ-6’s
This system is very similar to the single zone receiver/single MRZ-6 system. See Figure 20.
• A 12VDC wall adapter is connected to the switched outlet of each of the Preamp/Receivers to provide sync
(or status) to their MRZ-6.
• The CONTROL OUT of each MRZ-6 is connected to the input of the AC-3 which is used to power up those
shared sources which have latching power. Note: The MRZ-6 is diode isolated internally, blocking diodes
are not required.
• DATA OUT of the Slave is connected to the DATA IN of the Master. The Slave will pass IR data to the Master
for control of the shared sources via the Master’s common flasher outputs. See Figure 15.
• The UART connection enables All On and All Off control of all the rooms in the system. See page 20 of the
MRZ-6 manual.
• Both ZONE DIP switches should be set to the DOWN (or multi-zone) position. In this position, IR com-
mands passed through the other MRZ-6’s will not be routed to the Dedicated flasher. This enables identical
Preamp/Receiver commands to be used for both the home theater and the multi-room sound systems inde-
pendently, while the commands used to control the shared sources are output via the Master MRZ-6’s
Common flasher outputs.
• When using RP-9 keypads with or without IntelliPads or IR sensors, all automation codes are taught to both
MRZ-6’s.
For more information concerning IntelliPad®/MRZ-6 programming, see page 126of MRZ-6 manual.
