This unit comprises 9 independent power amplifiers, each being capable of reproducing the same quality sound through
its channel. Note that you should connect an input source and a speaker to each channel in use.
Caution
• Do not connect the power cord until you have finished all other connections.
• Read the instructions that came with the other components you are connecting.
• Do not make connections to input or output jacks while the amplifier is turned on.
• Turn the volume of the control amplifier down before turning on the amplifier.
Balanced Input (XLR terminal)
Connect AV controllers or control amplifiers with
balanced outputs for high-quality sound.
The pin assignments for this terminal are given above.
This pin assignment conforms to the standard adopted
by the Audio Engineering Society. Refer to the
instruction manual supplied with the control amplifier
and verify that its output terminal is compatible with
the pin assignments for this terminal. The output
terminal of Onkyo PR-SC5509 is compatible with the
pin assignments for the terminal of the amplifier.
The amplifier uses the European type XLR terminal.
Phase is reversed when an XLR cable is connected to
the control amplifier that uses the USA type XLR
terminal. In this case, swap pin 2 and pin 3 to set the
polarity to the European type before connecting.
Plugging the XLR cable
Match the pins and insert the terminal until you hear a
“click.” Make sure that the terminal is locked by lightly
pulling the connection cable.
Unpugging the XLR cable
Pull out the connection cable while holding down the
lever.
Note
• When using this balanced connection for a specific channel
between the control amplifier and the amplifier, set the INPUT
SELECT switch to the upper side (the balanced input side) to
select balanced input. Next, use commercial XLR balanced
cable and connect the balanced output from the control amplifier
to the corresponding balanced input on the amplifier.
• Do not connect anything to the RCA-type audio input jack.
