PCM Effects and Parameters

SURROUND ROLLOFF allows the high frequencies of the surround

channels to be attenuated with the same detection circuitry as that

described for the Soundstage control. The attenuation is quite attractive

on many music and broadcast sources which were not mixed for

surround. When a surround source is detected, these filters are re-

moved, so the rear speakers can reproduce surround events with full

bandwidth. This control should be set high enough to give presence and

airiness to the rear sound without placing distracting instrumental

overtones or other sounds behind you. The settings also affect the side

outputs.

SURROUNDS selects the type of surround decoding used by the

MC-1. STEREO provides extraction of five channels of surround infor-

mation from a standard 4-2-4 matrix-encoded soundtrack (Dolby Sur-

round, Ultra*Stereo, etc.) The drama of this effect is dependent on the

source material and is most noticeable with strong stereo music

soundtracks. The DECORRELATED setting electronically alters the

monaural surround channel to provide added spaciousness and envel-

opment.

VOCAL ENHANCE boosts vocals in the center channel. By targeting

specific frequencies, it can boost only vocals, without raising the entire

center channel level (which would alter the output balance achieved

during calibration).
