Acoustical Parameters (cont.) - Bass Sum & Redirect
OPTION THREE - Subwoofer has an active crossover & all front speakers are small.
For the best results, three identical loudspeakers should
be used for the center, front left, and front right chan-
nels. These speakers can be THX Home theater speak-
ers or other small front channel speakers and for this
option, need to be used with a subwoofer that has its
own built-in active crossover. If the subwoofer has an
active crossover, it can filter out high frequencies, per-
mitting only low frequencies to go to the driver. If this is
the case with your home theater system, you can redi-
rect the bass signal from the front channel speakers di-
rectly to the subwoofer. It is presumed that the Global
Speaker Configuration Settings for the main five chan-
nels is already set to "Small Speakers" (80Hz Filter On).
Step 1
Repeatedly press the INPUT SELECT button until the first Input Label appears, typically
this will read as "LASER AC3 1".
Step 2
Press the MODE button to make certain that you are not in the "STEREO", "QUAD BY-
PASS", or "DIRECT" mode (the DIRECT mode is automatically engaged for an Input Label
set to the Multi-Pin Input for DTS Decoding). If this is a DTS Input Label, skip to step 5.
Step 3
Repeatedly press the SETUP MODE button until the display reads one of the following:
"NO REDIRECT", " C TO LF/RF", "LRF/C TO SUB", or "C TO SUB"
Step 4
Repeatedly press the VOL UP button until the display reads "LRF/C TO SUB".
Step 5
Press the ALL button to set the Bass Sum to the desired setting (typically "LCRS+LFE=SUB"
for Pro Logic/AC-3/Music and "SUM-10DB=SUB" for DTS. "LFE ONLY=SUB" can be used
for DTS and AC-3 playback of film material if desired.)
Step 6
Press the INPUT SELECT button once to exit the "Setup Mode".
Step 7
Turn on the source component for this Input Label and engage it into play. Momentarily
press the VOL PRESET button to recall the volume level set with Pink Noise. During this
setup, it is recommended that the volume levels for the five main channels not be altered.
Step 8
Press the ALL button until the display reads "SUB ### DB". Press the VOL UP and DN
buttons to adjust the bass level for this Input Label. You will want to use a film or music
segment which contains some bass information. Note that the bass level for each input is
individually adjustable and you may need to listen to a particular segment repeatedly.
Step 9
When the desired bass level is set, press and hold the VOL PRESET button until the
display reads "STORE VOL". This will add the new bass setting to the for this specific
Input Label to the other five channel's volume preset calibrated with pink noise.
Step 10
Press the INPUT SELECT button to advance to the next Input Label.
Step 11
Repeat steps 2-10 for each Input Label.
