The main volume control adjusts the volume of all of the
speakers up and down at the same time. They keep the
same relative levels as were originally selected.
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 PT-7010A
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 PT-7010A 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 PT-7010A, 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.
