Connect the supplied optimizer
microphone to the AUTO CAL
Set up the optimizer
Place the optimizer microphone at your
seating position. Use a stool or tripod so
that the optimizer microphone remains at
the same height as your ears. Orient the L
end of the optimizer microphone toward
the front left speaker and the R end of the
optimizer microphone toward the front
When you position the optimizer microphone
at the center of the two speakers, if the angle
between the two speakers is too narrow, the
optimizer microphone cannot measure the left
and right speakers properly.
On setting up the active
• When a subwoofer is connected, turn on the
subwoofer and turn up the volume
beforehand. Turn the MASTER VOLUME
knob to just before the mid-point.
• If you connect a subwoofer with the
crossover frequency function, set the value
• If you connect a subwoofer with an auto
standby function, set it to off (deactivated).
Depending on the characteristics of the subwoofer
you are using, the setup distance value may be
further away from the actual position.
To use the receiver as a pre-
You can use the auto calibration function when
you use the receiver as a pre-amplifier.
In this case, the distance value shown on the
display may differ from the actual distance
value. However, there will be no problems
even if you continue to use the receiver with
Performing auto calibration
The auto calibration function allows you to
measure the following:
• Speaker connections
• Polarity of speakers
• Speaker distance
• Speaker angle
• Speaker size
• Speaker level
• Frequency characteristics
a) This receiver corrects signals by analog
downmix processing only for the center speaker
and subwoofer when the multi-channel input is
selected. The correction is invalid for other
b) The measurement result is not utilized when the
multi-channel input is selected.
c) • Signals with a sampling frequency of higher
than 96 kHz are always played back at either
44.1 kHz or 48 kHz.
