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 relative 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 whenever 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 surround speakers
with the same range of adjustment between 40-160Hz.
If you set the L-R CROSSOVER to 80 HZ (a good starting
point), left and right channel main speakers set to SMALL
receive frequencies above 80 Hz. The frequencies 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 information 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 automatically
engaged. It also has no effect in 5.1 or greater surround
modes.
