Adjusting the acoustic image (BI-Phantom)
In most installations, the center speaker must be placed directly between
the front passenger and driver. Using this function, the center channel
information is distributed to the left and right speakers. This creates an
acoustic image simulating a center speaker directly in front of each
listener. Adjusting the center width in PL II MUSIC (see “Using the Pro
Logic II Mode” on page 27), makes this function ineffective.
• 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.
Touch [ ] or [ ] of BI-Phantom to adjust the level.
The level can be adjusted within the range of -5 to +5. The
higher the level, the more the position of the center speaker is
shifted to the sides.
The BI-Phantom function is turned off by touching [OFF].
• This adjustment is effective when the setting of the center speaker to
SMALL or LARGE in the speaker setup settings.
• This adjustment is ineffective when the speaker is set Center to OFF
in “Setting the Speakers” (page 29).
Mixing bass sound to the rear channel (Rear MIX)
This function mixes the front channel audio signals to the audio signals
output from the rear speakers, improving the sound in the vehicle’s rear
seat.
• 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.
Touch [ ] or [ ] of Rear MIX to adjust the level.
The level can adjusted in five steps: -6, -3, 0, +3 and +6. The
higher the level, the more bass is output from the rear speakers.
(The effect differs according to the software (DVD, etc.).)
The Rear MIX function is turned off by touching [OFF].
• This adjustment is ineffective when the rear speaker setup setting is
set to “OFF”.
• For linear PCM signals, the voice is output from the rear speaker
regardless of the REAR FILL and Rear MIX setting.
Achieving powerful high volume sound (Listening Mode)
With Dolby Digital, the dynamic range is compressed so that powerful
sound can be achieved at regular volume levels. This compression can
be canceled to achieve an energetic sound with even greater power, like
the sound in a movie theater. This function works only in the Dolby
Digital mode.
Touch [ ] or [ ] of Listening Mode to select STD or MAX.
• Keep the volume to a level at which sounds outside the vehicle can
still be heard.
Adjusting the speaker levels (Output Level)
The test tones help to make the volume adjustments of the different
speakers. When levels are equal, a strong sense of presence can be heard
from the different speakers at the listening position.
• 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.
1 Touch [ON] of Output Level.
Test tone output is repeated for each of the different
speaker channels. They will be repeated in the order
shown below.
If no operation is performed for 2 seconds, the channel
switches to the next channel.
2 While the test tone is being produced from the speakers,
touch [ ] or [ ] of Output Level balance the output from
all the speakers.
3 Touch [ON] again to turn OFF.
• If a speaker is set to off mode, that speaker’s level adjustment cannot
be made. Refer to “Speaker Setup” (page 30).
The PXA-H700 or PXA-H701 can be set according to the playable
frequency range of your speakers.
Check the playable frequency range of the speakers (not including the
subwoofer) before performing this operation to verify whether the
speakers can play low frequencies (of about 80 Hz or less).
• 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 Decode mode is switched.
