On setting up the active sub 
woofer
• When a sub woofer is connected, turn on the 
sub woofer and turn up the volume 
beforehand. Turn the MASTER VOLUME 
knob to just before the mid-point.
• If you connect a sub woofer with the 
crossover frequency function, set the value 
to maximum.
• If you connect a sub woofer with an auto 
standby function, set it to off (deactivated).
Note
Depending on the characteristics of the sub woofer 
you are using, the setup distance value may be 
further away from the actual position.
Using 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 sub woofer 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 more than 
96 kHz are always played back at either 
44.1 kHz or 48 kHz.
• The measurement result is not utilized in the 
following cases.
–The multi-channel input is selected.
–“2ch Analog Direct” is being used.
–Dolby TrueHD signals with a sampling 
frequency of more than 96 kHz are being 
received.

Make sure that the AMP button 
is lit.
If it is not lit, or “GUI MODE” is not 
displayed in the display window of the 
receiver, follow the steps given in “7: 
Operating the receiver using the GUI 
(Graphical User Interface)” (page 38).
