Alpine IVA-D901 owner manual Using the ProLogic II Mode, Linear PCM Setting, 51-EN

Using the ProLogic II Mode

Pro Logic processing can be conducted on the music signals recorded on two channels to achieve Dolby Pro Logic II surround sound. For two-channel Dolby Digital and DTS signals, there is also a “REAR FILL” function for outputting the signals of the front channel to the rear channel.

1 Check that Defeat mode is off.

2 Press SOURCE/POWER.

The main menu is displayed.

3 Press 4 (A.PROC).

The A.PROC (Audio processor) list display appears.

4 Turn the Rotary encoder to select “DOLBY PL II.”

The Function Guide changes.

5 Press 1 (SETUP).

The DOLBY PL II adjustment display appears.

6 Turn the Rotary encoder to select DOLBY PL II.

7 Press the function button to select your desired mode.

PL II MOVIE:

Suits the stereo TV shows and all programs encoded in Dolby Surround. It improves the sound field directivity to near that of discrete 5.1-channel sound.

PL II MUSIC:

Can be used for all stereo music recordings, and provides a wide, deep sound field.

REAR FILL:

Depending on the input signals, the sound may only be output from the front speakers. In this case, the "REAR FILL" function can be used to output signals from the rear speakers as well.

OFF: Turns DOLBY PL II function to OFF.

If PL II MUSIC is selected, the center width can be adjusted with following operations.

This function offers the optimum vocal position by adjusting the center channel position between the center speaker and the L/R speaker. (The adjustments established in “Adjusting the acoustic image” (page 49) are ineffective while this function is activated.)

1Turn the Rotary encoder to select CENTER WIDTH CONT.

The Function Guide changes.

2Press 2 (ON).

By pressing 1 (OFF), the CENTER WIDTH CONT function is turned to OFF.

3Press 3 (LEVEL ;DN) or 4 (LEVEL UP :) to adjust the level.

The level can be adjusted between 0 to 7. When the level increases, the center channel position moves from

the center speaker position to both sides.

•This adjustment is effective when the setting of the center speaker is SMALL or LARGE in the speaker setup settings.

•Avoid stopping, pausing, switching the disc, cueing, fast- forwarding or switching the audio channel of this unit while making this adjustment. The setting is canceled if the Decode mode is switched.

•This adjustment is ineffective when the speaker is set to CENTER OFF in “Setting the Speaker” (page 45).

•This function only works with two-channel signals. This operation is ineffective when 5.1-channel DTS or Dolby Digital signals are input.

•If the setting of REAR FILL is made when REAR MIX is ON, sound is unchanged in the rear fill setting because REAR MIX is given priority during 2 channel decoder other than linear PCM.

•For linear PCM signals, the voice is output from the rear speaker regardless of the REAR FILL and REAR MIX setting.

Linear PCM Setting

The output when playing discs recorded in linear PCM can be set to 2 or 3 channels.
