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 (Power 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 stan-
dard 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 ter-
minal. The output terminal of Integra DTC-80.1 is
compatible with the pin assignments for the termi-
nal of the amplifier.
The amplifier uses the European type XLR termi-
nal. Phase is reversed when an XLR cable is con-
nected 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.
Notes:
• When using this balanced connection for a specific
channel between the control amplifier and the ampli-
fier, set the INPUT SELECT switch to the upper side
(the balanced input side) to select balanced input.
Next, use commercial XLR balanced cable and con-
nect 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.
