To ensure your safety, please read these instructions before operating this unit.
1. Follow all instructions and warnings marked on the unit.
2. Always use the correct line voltage. Please refer to page 6, and find out the correct
power requirements in your area. Please note that different operating voltages may
require the use of different adapters.
3. Do not install the unit in an unventilated rack, or directly above heat producing
equipment such as power amplifiers.
4. Please do not block the openings on both sides of the case for better ventilation.
5. To avoid shock or fire hazard, do not expose the unit to rain or moisture, or operate it
where it will be exposed to water.
6. Do not attempt to operate the unit if it has been dropped, damaged, exposed to
liquids, or if it exhibits a distinct change in performance indicating the need for
service.
7. Only qualified service personnel should open this unit.
8. Removing covers will expose you to hazardous voltages.
9. Do not overload wall outlet, extension cords or integral convenience receptacles, as
this can result in a risk of fire or electrical shock.

Installation
lTurn off any electrical or computer device that you plan to connect to the DD-5.1.
lSlowly unpack the DD-5.1 and its accessories from their packaging.
lPlace the DD-5.1 on a flat, stable surface, preferably on a T.V shelf, allow a space of
at least 10 cm above, behind and apart from any object.
lLocate the DD-5.1 near your source equipment so you can use the shortest possible
interconnect cables. Keep your DD-5.1 away from moisture sources such as open
windows and heat sources such as hot air ducts radiators. Also, you should keep the
unit away from direct sunlight since it could interfere with the remote control sensor.
lThe DD-5.1 Surround Sound Decoder has a very flexible connectibility. It accepts
both digital and analog audio signals from CD Player, VCR, DVD player, TV monitor,
Computer and Game Consoles (Nintendo N64, Sega Dream Cast, SONY PlayStation
II etc.)
lDD-5.1 can be connected to an external amplifier or our Promedia 5.1 speaker
system; in page 9 and 10, different diagrams can clearly illustrate the proper
installation of DD-5.1 depending on different audio sources, amplifiers and speakers.

DD-5.1 Operation – Delay Calibration
SL SR
RL

The ideal listening position is defined as below:
lCenter channel speaker should be placed in a position that has an equal distance as
the left and right speakers to listener.
lSurround left and surround right speakers should be placed on the backside of
listener and above listener’s ear level.
lIf speaker placement is restricted due to the physical environment of the room, delay
calibration is sometimes necessary to achieve the ideal listening environment.
lIn case center speaker only can be placed in a position that has a closer distance to
listener than that of left and right speakers. The sound from the center speaker might
arrive to the listener before the left and right speakers. The difference in sound arrival
time would ruin the sound quality and effect, even the best DVD titles. Fortunately
DD-5.1 allows you to adjust the center speaker time delay to compensate this
problem by increasing the delay time for the center channel. Thus sound from the
center, left and right speakers reach the listener at the same time. If your center
speaker is closer to the listening area than the left and right speakers. Press DELAY
Button repeatedly until the Center channel is reached. To increase or decrease the
delay time, press D TIME + or D TIME - until a desire distance is matched. Same
procedures can be applied for adjusting the delay time of surround speakers if
necessary.
