Adjusting the speaker levels

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 cancelled if the decode mode
is switched.

Mixing bass sound to the rear channel

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 cancelled if the Decode

contents. For storing, refer to page 37.

Adjusting the acoustic image

In most installations, the centre speaker must be placed directly
between the front passenger and driver. Using this function, the centre
channel information is distributed to the left and right speakers. This
creates an acoustic image simulating a centre speaker directly in front
of each listener. Adjusting the centre width in PL II MUSIC (see
"Using the Pro Logic II Mode," page 36), 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 cancelled if the Decode mode is switched.
