Subwoofer setup

(For HTR9900 only)
Fine-tune the subwoofer setting based on your
listening preferences.
1
Turn the subwoofer on with the POWER
switch,
2
Play music with bass content.
3
Turn the OUTPUT LEVEL switch
clockwise until you begin to hear the
source. Adjust the volume output to a
comfortable listening level.
4
Switch the PHASE switch to '-180°'. This
will let you determine if the bass sounds
louder in your seating position. The more
bass-heavy setting is where the output of
the subwoofer and the main speakers are
most in phase. Use whatever position is
louder at your seating location. However, if
you do not notice any difference when
changing the setting, it only means there
are no issues in your room and all is fi ne.
5
With the overall level at a reasonable
volume, walk around the room. Listen for
the balance between the subwoofer and
the speakers. If there is too much low
frequency sound, turn the FREQUENCY
switch counter-clockwise towards "80 Hz"
If more bass is needed, turn the
FREQUENCY switch towards "160 Hz".
Adjust for a good even balance.
Note
•
For HTR9900, the default frequency is 80 Hz.
