MASTER LEVEL adjusts the output level of the two-channel downmix.
This control should be set to +5dB unless the LFE is very heavy, in which
case the level should be reduced.
RE-EQUALIZER equalizes the left, center, and right channel outputs to
match the overall frequency balance of the original recording. Without
this re-equalization, many films and some television programs will
sound too bright.
REAR DELAY OFFSET is an additional delay added to the rear...

SURROUND ROLLOFF allows the high frequencies of the rear
channels to be attenuated with the same detection circuitry as that
described for the Soundstage control. The attenuation is quite attractive
on many music and broadcast sources that were not mixed for surround.
When a surround source is detected, these filters are removed, so the
rear speakers can reproduce surround events with full bandwidth. This
control should be set high...

DTS Logic 7
DTS Logic 7 combines all the features of DTS Digital with enhance-
ments by JBL Synthesis and LucasFilm. This effect uses Logic 7 matrix
technology to enhance the steering between the side speakers and the
rear speakers, so sounds intended to come from behind the listener
actually do come from behind. This effect also includes the adaptive
decorrelation and re-equalizer features of DTS/THX.
DTS Logic 7 provides the ultimate in film reproduction. It...

DTS/THX
This Effect provides THX 5.1 enhancements for film soundtracks
recorded in the DTS format. This processing compensates for the
acoustical differences between large mixing theaters and the typically
smaller home environment. In this...

RE-EQUALIZER equalizes the left, center, and right channel outputs to
match the overall frequency balance of the original recording. Without
this re-equalization, many films and some television programs will
sound too bright.
REAR DELAY OFFSET is an additional delay added to the rear
channels when listening to LOGIC 7 and MUSIC SURROUND. This
delay increases the apparent size of the listening space by increasing
the rear delay time. Feel free to experiment to...

If you encounter a problem, please review the items in the following
checklist. Also be sure to thoroughly check all other connected compo-
nents such as speakers, equalizers, amplifiers, VCR, TV, CD player, etc.
Problem Possible Cause and Solution
Power does not come on Check line cord to ensure good connection to the AC outlet and to the
receptacle on the SDP-3 rear panel. Check to make sure that the SDP-
3 rear panel power switch...

Problem Possible Cause and Solution
No Video Make sure that video cables (particularly S-Video cables) are fully
inserted and that the appropriate connector is assigned to the VIDEO IN
parameter in the Input Configuration menu.
Hum Finding and eliminating audio hum in a complex installation can be a
very frustrating task. Often, the easiest way to identify the culprit(s) is to
systematically eliminate devices from the audio chain. If Cable TV is
connected to any component...

Routine Maintenance
Other than occasional replacement of the batteries in the remote
control, the SDP-3 requires minimal  maintenance. Use a soft, lint-free
cloth slightly dampened with warm water to clean the exterior surfaces
of the unit.
Do not use alcohol, benzene or acetone-based cleaners
or any strong commercial cleaners.
Do not use abrasive materials such as steel wool or metal polish. If the
unit is exposed to a dusty environment, a...
