Parameters

Effect Level

The term Dolby Stereo refers to both movies and equipment used exclusively for theatrical

presentation. When one of these movies is transferred to commercial video media, the special

audio encoding of the Dolby Motion Picture matrix is retained in the two-channel stereo

soundtrack. The resulting video software and the hardware designed to reproduce it use the

name Dolby Surround to distinguish it from the theatrical optical format.

Dolby Pro Logic Surround decoding is the licensed consumer version of the professional

Dolby Stereo cinema processors, which allows the home viewer to obtain all the spatial

effects of the soundtrack heard in a theatre over a wider range of seating positions than

conventional Dolby Surround playback.

The SURROUND programs are designed for film sound tracks and they

make full use of additional loudspeakers at the center, sides and rear of the

room. MONO LOGIC takes a monaural soundtrack and sends music and

sound effects to the sides and rear through a room simulator program, while

keeping dialog in the center. STEREO LOGIC is meant for playing music

through a system whose speakers are laid out primarily for films. PRO

LOGIC is Lexicon’s all-digital implementation of the Dolby Pro Logic

Surround decoding process.

TREBLE

SET PROGRAM NAME

MEMORIZE PROGRAM

TREBLE is the only adjustable parameter in MONO LOGIC. It regulates the

treble cut in the side and rear channels. The optimal setting for this

parameter will vary widely with the age, quality and condition of the

source material.

EFFECT LEVEL conrols the level of all channels except the center. The center

will appear stronger if you turn down EFFECT LEVEL a few dB. With

EFFECT LEVEL all the way down, the center only will play.
