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.

Adjusting the acoustic image

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" page 42), 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.

The level can be adjusted within the range of –5 to +5. The
