First Time Setup—Continued
Changing the Speaker Settings Manually
If you wish to make changes to the settings found during
the automatic speaker setup, follow the directions on see
pages 73–80.
Notes:
• Please note that THX recommends any THX main
speakers be set to “80Hz(THX)”. If you set up your
speakers using the Automatic Speaker Setup function,
please make sure manually that any THX speakers are
set to 80 Hz (THX) crossover (see page 73).
• Sometimes due to the electrical complexities of sub-
woofers and the interaction with the room, THX rec-
ommends setting the level and the distance of the
subwoofer manually.
• Sometimes due to interaction with the room, you may
notice irregular results when setting the level and/or
distance of the main speakers. If this happens, THX
recommends setting them manually.
Using a Powered Subwoofer
If you’re using a powered subwoofer and it outputs very
low-frequency sound at a low volume level, it may not be
detected by the automatic speaker setup.
If the “Subwoofer” appears on the “Review SP Configu-
ration” screen as “No”, increase the subwoofer’s volume
to the half-way point, set it to its highest crossover fre-
quency, and then try running the automatic speaker setup
again. Note that if the volume is set too high and the
sound distorts, detection issues may occur, so use an
appropriate volume level. If the subwoofer has a low-
pass filter switch, set it to Off or Direct. Refer to your
subwoofer’s instruction manual for details.
