Crossover adjustment
The TGP-5 bass management
system allows you to send the low
frequencies of your speakers to a
subwoofer. The crossover point of
your main left and right speakers can
be selected from 40 Hz to 160 Hz, as
can the crossover point of your center
and surround speakers.
For example, if your main left and
right speakers are a bit lacking in bass
response, you can set the speaker
size to SMALL, and set the L-R cross-
over to 40 Hz. The subwoofer will then
receive the lower bass range, (not
well reproduced by your front speak-
ers). This will not affect the range sent
to your center or surrounds.
A setting of 80 Hz is a good start-
ing point if you are not sure of the
response of your speakers. In this
example:
• 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.

SUBWFR MODE ENHANCED BASS
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.
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
TGP-5'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 TGP-5, there would be a hole in
the mid-bass, and bass information
would be missing.
