Dolby Digital, Dolby Pro Logic and DTS soundtracks are designed to be played back on a
properly calibrated Home Theater. The sounds from each speaker will be at the correct rela-
tive levels, as the movie sound director designed them. Repeat the calibration if you change
any speakers or your external power amplifiers. You should also run a new calibration when-
ever you move your seating relative to the speakers.
Note: The range of adjustment is +/– 10 dB for each speaker.
Crossover Adjustment
The bass management system built into the DMC-1 allows
you to redirect the low frequencies of your main and surround
speakers to a subwoofer. The crossover point of the left and
right main speakers can be selected from 40 Hz to 160 Hz.
There is an additional selection for the center and sur-
round speakers with the same range of adjustment be-
tween 40-160Hz.
If you set the L-R CROSSOVER to 80 HZ (a good start-
ing point), left and right channel main speakers set to
SMALL receive frequencies above 80 Hz. The frequen-
cies below 80 Hz are then redirected to the subwoofer.
The same scenario applies to the C-SURR setting for
center and surround speakers.
Most manufacturers provide a -3 dB specification for their speakers. This is the frequency
where the speaker’s output has dropped by 3 dB. Set the DMC-1 crossover to this frequency
or above. If you cannot find this, set the crossover to 80 Hz (the default). Set your subwoofer’s
own crossover control to maximum frequency or bypassed mode. If it is set lower than the
DMC-1, there would be a hole in the mid bass, and bass informa-
tion would be missing.
Subwoofer Mode
The subwoofer output can be set to NORMAL or 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 auto-
matically engaged. It also has no effect in 5.1 or greater
surround modes.
