Customization
After you have calibrated and customized the SDP-3, there are two
additional steps recommended to safeguard the settings. First, docu-
ment your adjustments using the worksheet at the end of this manual.
Second, consider locking the settings so that they cannot be inadvert-
ently changed. The last item in the Setup menu allows you to lock the
SDP-3 settings, as well as to change the name displayed during power  up.

Using SDP-3 Effects
When EFFECT ADJUST is selected from the Main menu, the on-screen
display shows a list of parameters specific to the current effect, as well
as the current value of each parameter. (The front panel display shows
one parameter at a time). Use the ▲ and ▼  buttons to move through the
displayed list. Press SELECT to activate a two-line display which allows
you to use ▲ and ▼ to alter the selected parameter’s value. Press...

Restoring the original parameter values  of an Effect
The RESTORE PARAMETERS function allows you to restore the
currently selected Effect to its factory preset state. When you select this
function, you will be prompted to reconsider erasing your changes. If you
don’t want to erase your versions, press DONE to exit the menu.
Pressing SELECT in response to the displayed query will restore all of
the factory preset values to the Effect.

The PCM Effects are compatible with two-channel input signals (analog
or digital).
Panorama
Panorama extracts the natural ambience from recorded music and
moves it outward from the speakers, producing greater width and depth
of image and a feeling of enhanced spaciousness. This mode adds no
additional sound but expands the existing stereo image. Panorama also
works with Dolby Stereo movies, bringing the surround track outward
into the...

Football
The Football Effect uses a reverberation algorithm, which differs from
ambience in that it does not simulate the reflections of specific halls, but
emphasizes rich, smooth reverberant decay in small and medium
spaces. It works well for simulating a space with a long reverberation
time relative to its size, and for simulating the sound of a live sporting
event.

Rock/Pop
Rock/Pop is a  surround effect developed specifically for music listening.
It makes full use of additional loudspeakers placed at the center, sides
and rear of the room and provides a slight degree of steering for the front
channels. (Music Surround, passes unprocessed left and right informa-
tion directly to the front left and right speakers.)

PCM Effect Parameters
5 SPEAKER ENHANCE simulates 7 speaker playback through a 5
speaker system, providing a heightened sense of spaciousness and
envelopment without extra speakers. This enhancement is most notice-
able if the surround speakers are positionned directly to the side of the
listening position, or if the listening position is located against the rear
wall.
Note that, although this provides very convincing improvement to a 5
speaker system, it is not...

BASS RT (low frequency reverberation time) depends on MID RT and
is expressed as a multiplier. BASS RT should be set to 1.0 x MID RT for
a more natural effect in smaller spaces.
CENTER LEVEL adjusts the output level from the center speaker.
EFFECT LEVEL adjusts the loudness of the side and rear speakers.
When there are no side speakers, it adjusts the amount of ambient
signal mixed into the main loudspeakers. In Panorama, this...
