Set up the optimizer
microphone.
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.
On setting up the active
subwoofer
• 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
to maximum.
• If you connect a subwoofer with an auto
standby function, set it to off (deactivated).
Note
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-
amplifier
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
that value.
The auto calibration function allows you to
measure the following:
• Speaker connections
a)
• Polarity of speakers
• Speaker distance
b)
• Speaker size
b)
• Speaker level
• Frequency characteristics
c)
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
speakers.
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.
