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.
