Optimizer microphone • 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). Getting Started 1 Connect the supplied optimizer microphone to the AUTO CAL MIC jack. 2 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. Orient the L end of the optimizer microphone toward the front left speaker and the R end of the optimizer microphone toward the front right speaker. Note 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 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. 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 preamplifier 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. Performing auto calibration The auto calibration function allows you to measure the following: • Speaker connectionsa) • Polarity of speakers • Speaker distanceb) • Speaker sizeb) • Speaker level • Frequency characteristicsb) c) a) This receiver corrects signals by analog downmix processing only for the center speaker and subwoofer when the multi-channel input is selected.

Getting Started
1
Connect the supplied optimizer
microphone to the AUTO CAL
MIC jack.
2
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. Orient the L
end of the optimizer microphone toward
the front left speaker and the R end of the
optimizer microphone toward the front
right speaker.
Note
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
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
b) 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 in the
following cases.
–
The multi-channel input is selected.
–
“2ch Analog Direct” is being used.
