REAR DELAY in both STEREO LOGIC and PRO LOGIC is adjustable.
Generally, the correct delay is about 20 milliseconds but the setting depends
on speaker set-up and source material. In general, the delay should not be
so great that the rear sound becomes identifiable as a distinct source.
REAR ROLLOFF controls the treble attenuation and should be adjusted on
music for maximum airiness and spatial realism without causing specific
instruments to seem to come from behind you. Stereo Logic's REAR
ROLLOFF parameter contains an AUTOMATIC mode. In this mode the
rear channels are rolled off above 7 kHz until the logic circuits steer a sound
effect to the rear speakers, whereupon the bandwidth opens up to beyond
15 kHz. This will enhance the realism of some effects that move from front
to rear or vice-versa.
