Adjusting The Subwoofer Before Use - Yamaha RX-V765 Owner's Manual

ADJUSTING THE SUBWOOFER BEFORE USE

Before using the subwoofer, adjust the subwoofer to obtain the optimum volume and tone balance between the subwoofer
and the main speakers by following the procedures described below.
1
Set the VOLUME control to minimum (0).
2
Turn on the power of all the other components.
3
Make sure that the POWER switch on the rear panel is
set to the ON position, then press the STANDBY/ON
switch on the front panel to turn on the subwoofer.
* The status indicator lights up in green.
4
Play a source containing low-frequency signals and
adjust the amplifier's volume control to the desired
listening level.
5
Adjust the HIGH CUT control to the position where
the desired response can be obtained. Normally, set the
control to the level a little higher than the main
speaker's rated minimum reproducible frequency*.
* The main speaker's rated minimum reproducible
frequency can be looked up in the speakers' catalog
or owner's manual.
6
Increase the volume gradually to adjust the volume
balance between the subwoofer and the main speakers.
Normally, set the control to the level where you can
obtain a little more bass effect than when the
subwoofer is not used. If the desired response cannot
be obtained, adjust the HIGH CUT control and the
VOLUME control again.

Set the PHASE switch to the position which gives you
the better bass sound. Normally, set the switch to the
REV (reverse) position. If the desired response cannot
be obtained, set the switch to the NORM (normal)
position.
Notes
• Once the volume balance between the subwoofer and
the main speakers is adjusted, you can adjust the
volume of your whole sound system by using the
amplifier's volume control. However, if you change
the main speakers to others, you must make this
adjustment again.
• For adjusting the VOLUME control, the HIGH CUT
control and the PHASE switch, refer to
"FREQUENCY CHARACTERISTICS" on page 14.
