Connecting the TX-NR901
—Continued
If you want to use the TX-NR901 as a preamp and con-
nect an external power amp, for example, a multichannel
power amp that’s more powerful than the TX-NR901’s
built-in power amp, you can connect it to the PRE OUT
outputs. In this case, you should connect all speakers and
the subwoofer to the external power amp.
If you have a powered subwoofer, connect it to the
TX-NR901’s PRE OUT SUB output.
With (Remote Interactive) you can control your
-compatible Onkyo CD player, DVD player, and so
on with the TX-NR901’s remote controller, and use the
following special functions:
•To use , you must make an RCA/phono analog
audio connection between the TX-NR901 and the
other AV components, even if they are connected
digitally.
Auto Power On/Standby
When you start playback on an AV component con-
nected via , if the TX-NR901 is in Standby, it will
turn on and select that AV component as the input source
automatically. Similarly, when the TX-NR901 is set to
Standby, all components connected via also enter
Standby. This function will not work if a component’s
power cord is connected to an AC OUTLET on the
TX-NR901.
Direct Change
When playback is started on an AV component con-
nected via , the TX-NR901 automatically selects that
AV component as the input source.
Remote Operation function
With the TX-NR901’s remote controller, you can oper-
ate -compatible Onkyo components.
Notes:
• Push plugs in all the way to make good connections.
• Use only cables for connections. An
cable is not included with the TX-NR901.
• Some AV components have two sockets, you can
connect either one to the TX-NR901. The other is for
connecting additional -compatible components.
• Connect the TX-NR901’s socket to only Onkyo
AV components. Connecting to other manufacturer’s
AV components may cause them to malfunction.
• Some components may not support all functions.
Refer to the manuals supplied with your components.
