Subwoofer Mode
The subwoofer output can be set
to Normal, or to an Enhanced Bass
mode.
The Enhanced Bass mode provides
an output to your subwoofer even
when you are listening to a stereo
source with main speakers set to
LARGE. In the Normal mode, there
would be no subwoofer output in this
case, and the bass would only come
from the main speakers.
The Enhanced Bass mode has no
effect if the main speakers are set to
SMALL, as the subwoofer is automati-
cally engaged. It also has no effect in
5.1 or greater surround modes.

Crossover adjustment
The TGIII bass management
system allows you to send the low
frequencies of your speakers to a
subwoofer. The crossover point can
be selected from 40 Hz to 160 Hz.
For example, if you set the cross-
over to 80 Hz (a good starting point):
• The subwoofer receives frequen-
cies below 80 Hz, from all speak-
ers whose size is set to SMALL.
• All speakers set to SMALL, receive
frequencies above 80 Hz.
Most manufacturers provide a -3 dB
specifi cation for their speakers. This
is the frequency where the speaker's
output has dropped by 3 dB. Set the
TGIII's crossover to this frequency or
above. If you cannot fi nd this, set the
crossover to 80 Hz (the default).
Set your subwoofer's own cross-
over control to maximum frequency or
bypassed mode. If it is set lower than
the TGIII, there would be a hole in the
mid-bass, and bass information would
be missing.
