Using the Pro Logic II mode

With the PXA-H701, 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 Press the PLII/REAR FILL button and select the desired mode.

The setting mode is canceled if no operation is performed within 15 seconds after the mode is selected.

DOLBY PL II MOVIE DOLBY PL II MUSIC

OFF REAR FILL

*If DOLBY 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 24) are

ineffective while this function is activated.)

1)After selecting DOLBY PL II MUSIC, within

15 seconds, press and hold the PLII/ REAR FILL button for at least 2 seconds.

2)Turn the Rotary encoder to select “Center Width ON” or “Center Width OFF”, then press the ENTER button.

When the setting is turned ON, the optimum vocal position is offered by adjusting the center channel position between the center speaker and the L/R speaker.

3)Turn the Rotary encoder to adjust the level, then press the ENTER button.

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 side.

4)After the setting, press and hold the

PLII/REAR FILL button for at least 2 seconds.

NOTES

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

•This adjustment is ineffective if the center speaker is set to “OFF” or “Sub.W” in the speaker setup settings.

2 Once the settings are completed, press the DISP button.

DOLBY 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.

DOLBY PL II MUSIC: Can be used for all stereo music recordings, and provides a wide, deep sound field.

NOTES

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

•“REAR FILL” function

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.

•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.

•Once the settings are made, we recommend storing them in the memory. See page 28 for instructions.
