Output level adjustment
Figure 4c
Output level adjustment is a key part of the
configuration process for any surround sound
pro duct. It is particularly important for DVD-
Audio, as correct outputs will ensure that you
hear sound tracks with the proper directionality
and intensity.
NOTE: Listeners are often confused about the
operation of the surround channels. While some
assume that sound should always be coming
from each speaker, most of the time there will be
little or no sound in the surround channels. This is
because they are only used when a movie
director or sound mixer specifically places sound
there to create ambiance, a special effect or to
continue action from the front of the room to the
rear. When the output levels are properly set it is
normal for surround speakers to operate only
occasionally. Artificially increasing the volume to
the rear speakers may destroy the illusion of an
enveloping sound field that duplicates the way
you hear sound in a movie theater or concert
hall.
The default settings of the DMC 250 player is
0dB for all channels. In case you feel adjustments
are necessary in your setup, we advise you to
copy the settings currently in use with 5.1 sur-
round modes (for instance Dolby Prol Logic II) of
your AV receiver to the DVD player.
When the
SPEAKER LEVEL Adjust
menu first appears, the test tone is off. Use the
Navigation Button 9 and the Enter
⁄ / ¤
Button 6 to select any channel for adjustment
using an external source, such as a test disc, from
which to judge the output levels. When the chan-
nel to be adjusted, is highlighted in blue, press
the Enter Button 6 followed by the
Navigation Button 9 to raise or lower the
output level. However, before proceeding with
any manual adjustment we recommend that you
first use the DMC's internal test tone generator
and automatic sequencer to send a tone to each
channel so that you may verify that all speaker
connections have been properly made.
To turn the test tone on and have it automati cally
circulate among the channels, press the
Navigation Button 9 until the

tone will immediately begin to circulate clockwise
around the room, playing for two seconds in each
speaker before switching to the next speaker
position. The text presenting the active speaker
will highlight in blue to indicate which speaker
the sound should be coming from.
IMPORTANT NOTE: Because this test noise will
have a much lower level than normal music, the
volume must be lowered after the adjustment for
all channels is made, but BEFORE you return to
the main menu and the test tone turns off.
After checking for speaker placement, let the test
noise circulate again, and listen to see which chan-
nels sound louder than the others. Using the front
left speaker as a reference, press the
Navigation Button 9 on the remote when
the text of the loudspeaker to be adjusted is lit in
blue, to bring all speakers to the same volume
level. When one of the
the test noise circulation will pause on the channel
being adjusted to give you time to make the
adjustment. When you release the button, the
circulation will resume after five seconds. The on-
screen cursor-bar and the test noise can also be
moved directly to the speaker to be adjusted by
buttons 9 on the remote.

adjusting the next channel.
If you are using a sound-pressure level (SPL)
meter for precise level adjustment with the test
tone, set the individual output level for each
channel so that the meter reads 75dB,
C-Weighted Slow. After all settings are made turn
the main volume down.
You may also make these same adjustments with
complete manual control over the channel being
adjusted by pressing the

If you find that the output levels are either
uncomfortably low or high, you may repeat the
procedure. Return to Step 2 and adjust the mas-
ter volume either slightly higher or lower to
accommodate your particular room layout and
your tastes. You may repeat this procedure as
many times as necessary to achieve a desired
result. In order to prevent possible damage to
your hearing or your equipment, we emphasize
that you should avoid setting the master volume
above 0dB.
When all channels have an equal volume level,
the adjustment is complete. Use the
