Surround

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.

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.

Effect Level 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.

Treble

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.
