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 subwoofer 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.
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.
