Connecting Components not Reached by the Remote
Controller Signals (IR IN/OUT)
In order to use the remote controller to control the
receiver from a remote location, you will need to
prepare a multiroom kit (sold separately) such as one
listed below:
• Onkyo’s Multi-Room System kits (IR Remote
Controller Extension System)
• Multiroom A/V distribution and control system such
as those from Niles
®
and Xantech

Effective Sensor Layout
Example for the main room
If the receiver is located inside a cabinet or other
enclosure where the infrared rays from the remote
controller cannot enter, then operation with the remote
controller will not be possible. In such a case, it will be
necessary to install a remote sensor at a location outside
of the cabinet so that the infrared rays from the controller
can be sensed.
Example for the remote zone
The IR IN input allows you to control the receiver from
the remote zone with the remote controller even though
the remote zone may be on the other side of the building
from the main zone. The diagram below shows how to
make the proper connections for the remote zone.
Making Sensor Connections
When you place the IR receiver in the main room, connect
the cable from the connecting block to the IR IN terminal.
Make the connection as shown below. Do not plug any
equipment into the power outlet until all the connections
are complete.
Effective Sensor Layout
In this situation, you will need to use a commercially
available IR emitter. Connect the mini plug of the IR
emitter to the IR OUT terminal on the receiver and then
place the IR emitter on the remote sensor of the
component or facing it. When the IR emitter is
connected, only the signal input to the IR IN terminal is
output to the IR OUT terminal. The signal input from the
remote sensor on the front of the receiver will not be
output to the IR OUT terminal.
Making Sensor Connections
When you place the IR receiver in the main room, connect
the cable from the connecting block to the IR OUT terminal.
