Surround

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.

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.
