Connection

DVD PLAYER, CABLE BOX, SATELLITE RECEIVER (DSS), TELEVISION (MONITOR)

When connecting video components such as DVD players, cable boxes, satellite receivers and televisions, you can use different types of cables depending on how the video component is equipped.

Video connections:

If the video component is equipped with S-VIDEO jacks, it is recommended that it be connected to the DDR94 or directly to the television monitor using an S-VIDEO cable. S-Video cables provide better picture clarity and resolution. If the video component is not equipped with an S-VIDEO jack, use a conventional RCA to RCA composite cable to connect to the DDR94 or directly to the television.

The above illustration shows how to connect video components to the DDR94.

Note:

When connection more than one video component to the

DDR94 (ie: VCR and DVD player) it is easier to use either all S-Video cables or all RCA to RCA composite cables.

This allows both video signals (DVD and VCR) to be sent through the DDR94 to the TV monitor using just one video input on the TV (S-Video or RCA). Regardless of the video component being played DVD or VCR, the picture will always appear on the same video input of the monitor.

If you use both S-Video and RCA composite cables to connect different video components to the DDR94, you must also use both S-Video and RCA composite cables to connect the TV monitor to the DDR94.

For example, if you connect a DVD player to the DDR94 using S-Video cable and a VCR using an RCA to RCA composite cable, you must also connect the TV to the

DDR94 using both types of cables. This requires an S-Video cable from the S-Video monitor out jack on the DDR94 to an

S-Video input on the TV (ie. Video 1). In addition, you must use an RCA composite cable from the composite video monitor out jack on the DDR94 to an RCA composite video input on the TV but not the same input used for the S-Video cable(ie: Video 2). Using this type of dual cable video connection. you will need to switch the TV video input source from TV to Video 1 to Video 2 depending on the video source being played-TV, DVD or VCR.

Audio connections:

Some video components are equipped with special digital audio outputs (ie: DVD players). If your video component is equipped with a digital audio output, it is recommended that you connect to the DDR94 using a digital cable. Digital audio cables are required to use the

DTS and Dolby Digital surround sound modes. If you do not use digital connections, the DDR94 will only operate in Dolby Pro Logic, Dolby 3 Stereo, Theater, Hall, Stadium and Disco surround modes.

There are two types of digital cables - coaxial (75 ohm) and optical. The DDR94 is equipped with both types of digital inputs. These inputs are labeled DIGITAL/DTS/PCM on the rear of the unit. Connect the video component outputs to any one of the three digital inputs on the DDR94.

If the video component is not equipped with a digital output, use a dual RCA to RCA composite audio cable to connect to the DDR94. Make sure to connect:

White plug to white jack ( L : left )

Red plug to red jack ( R : right )

Note:

When an optical cable is used, remove the protection caps from the component and DDR94 before attempting to insert the optical cable. If not using an optical cable or if the cable is removed, always re-install the protection caps to prevent dirt and dust from entering the inputs. If using a coaxial digital cable, leave the protection caps in both the video component and DDR94.

Dolby Digital is a system developed by Dolby Laboratories that transmits 5.1 channels of digital signals.

The surround system developed for movie theaters using this system is called "Dolby SR-D (Surround Digital)".

Because each channel is completely independent, a realistic sound field with a "three-dimensional" feel is achieved which gives the sound a sense of distance, movement and relative position, creating a surprisingly real and powerful sense of presence.

Some Dolby Digital programs carry information that allow you to compress the dynamic range of sound track, without degrading the sound quality, for softer sound effects when you listen late at night.

* LFE: Low Frequency Extension

This channel delivers separate non-directional bass signals to an optional subwoofer for more dynamic deep bass sound effects.

Available Surround Modes

>

DOLBY PRO LOGIC Surround

When playing recordings of live music, this mode provides a feeling similar to actually being in a concert hall.

When this mode is selected, the normal program source is directed to the main speakers and a reverberated sound is directed to the surround speakers.

This mode is suited to program sources which contain a large amount of reverberation.

>

STADIUM Surround

Use this mode when playing movie or music videos which carry the U DOLBY SURROUND mark.

This mode provides the effect of being in a movie theater or live concert house - an effect with an intensity which can only be obtained through DOLBY PRO LOGIC SURROUND.

The main feature of DOLBY PRO LOGIC SURROUND is that the separation between the various channels is significantly improved from the 3 dB of previous systems to 26-40 dB.

As a result, the effect of the front/back/ left/right movement of the sound image, as well as the sense of fixed position in the sound image, is much clearer and more dynamic than before.

In addition, movie dialogue and other sounds which should naturally be heard from the center are output through an independent center channel, providing a high degree of focus for dialogue.

>

3 STEREO

The reverberation of this mode produces a sound field which recreates the sound of a stadium.

>

DISCO Surround

Gives a greatly expanded feel to powerful music such as dance or rock.

>

STEREO

Front speakers receive rear (surround) speaker signals in addition to front speakers signals.

Center speaker works similarly to Dolby Pro Logic mode.

This mode improves imaging without the use of rear speakers.

>

THEATER Surround

This mode provides a three dimensional effect similar to that of movie theater.

With this mode, you can enjoy a surround effect similer to

Dolby Surround sound even when playing a video program which is not encoded with the Dolby Surround system.

>

HALL Surround

To switch the surround mode to stereo mode, press the

STEREO button.

When DTS or DOLBY DIGITAL is selected, the surround sound is down mixed to 2 channel.

Speaker Configuration

1 2

It is important to perform speaker configuration prior to using the surround sound decoder.

This allows the unit to sense the available speakers and automatically select decoding modes. It is possible to receive multi-channel surround sound without a center speaker, but for best results with Dolby Pro Logic and Dolby Digital decoding, at least 5 speakers (Left, Center, Right, Left Rear and

Right Rear) should be used.

1 Each press of the SPEAKER CONFIGURATION button will change the desired Speaker Configuration shown on the display. (ex.: “F-LARGE”, “F-SMALL”, “C-

LARGE”, “C-NONE”, “S-LARGE” etc.)

When no action is taken for 5 seconds, the display returns to the normal mode.

2 Use the ADJUST ( b / 5 ) buttons to set the appropriate status.

FRONT SPEAKER Mode:

< F-LARGE: The mode to choose if a large speaker is installed.

Front channels output is full range.

< F-SMALL: The mode to choose when using compact speakers. When using small compact front speakers, it is recommended to connect a powered subwoofer to play the

LFE/Bass out channel.

Caution :

If the subwoofer selector is set to off, the LFE/Bass out frequencies are sent to the front speakers.

This can cause damage to small compact speakers when played at high volume.

CENTER SPEAKER Mode:

< C-LARGE: Use this mode with a large center speaker. The center channel’s output is full range.

< C-SMALL: Use this mode with a small center speaker. Bass frequencies below 90 Hz are output from the speaker selected by LFE/Bass Out.

< C-NONE (DTS/DOLBY DIGITAL/DOLBY PRO LOGIC mode only):

Use this mode if there is no center speaker. The center channel signal will be divided between the main L and R speakers.

SURROUND SPEAKER Mode:

< S-LARGE: The mode to choose if a large speaker is used or if a subwoofer is connected in parallel. The rear channels output is full range.

< S-SMALL:The mode to choose if small speakers are used.

Frequencies of 90Hz and below are output to the speaker selected by LFE/Bass Out.

SUBWOOFER OUTPUT

< SUB-ON : Choose if a subwoofer is used.

Low frequencies of 90Hz and below in the LFE channel and other selected channels are output to the subwoofer

< SUB-OFF : Choose if no subwoofer is used.

Low frequencies of 90Hz and below in the LFE channel and other selected channels are distributed between the front L and R speakers.

Delay Time

Delay Time

The delay time can be individually set for the Dolby

Digital/Dolby Pro Logic modes using the DELAY TIME

(CENTER/REAR) buttons.

When you adjust the delay time in the Dolby Digital mode, an additional 15 ms is automatically added to the surround channels in the Dolby Pro Logic mode. The current setting is shown on the display.

Delay Time Setting

Adjustable Range

DOLBY DIGITAL Mode:

0 ~ 15 ms in 1 ms step (S-Delay)

0 ~ 5 ms in 1 ms step (C-Delay)

DOLBY PRO LOGIC Mode:

15 ~ 30 ms in 1 ms step (S-Delay)

In the surround modes, the sound from the rear speakers should be delayed slightly, relative to that from the front speakers.

The optimum delay time will depend on acoustic properties, whether the walls and furnishings reflect or absorb sound, etc.

It is recommended that you try different delay times to obtain the best effect. The delay is digitally synthesized, for the highest sound quality with minimum noise and distortion.

The delay time can be set independently for each surround mode using the DELAY TIME buttons, with the current setting shown in the display.
