Centre mode

A setting used by the Dolby Pro Logic Surround mode to determine the kind of signal processing required to produce the surround effect with the speakers you have connected. The centre mode is determined automatically according to the setting of the speaker size parameters in the SP. SETUP menu.

This processor’s Dolby Digital (AC-3) circuitry provides a more versatile range of speaker settings than the standard Dolby Pro Logic centre mode setting. For your reference, the following chart shows the relationship between the Dolby Digital (AC-3) speaker size parameters and the Dolby Pro Logic centre mode.

FS = Front speaker size CS = Centre speaker size RS = Rear speaker size

several speakers positioned in places around or behind the listening position.

The number and angle of the simulated (virtual) speakers were developed to simulate the sound of the actual speaker arrangement in the editing rooms of Sony Pictures Entertainment, Hollywood.

These sound modes allow you to enjoy a truthful reproduction of the sound environment intended by the filmmaker, in the comfort of your own home.

Dolby Pro Logic Surround

Decoding system of Dolby Surround sound standardized in TV programmes and movies. Compared with the former Dolby Surround system, Dolby Pro Logic Surround improves sound image by using four separate channels: off-screen audio effects, on-screen dialog, left- to-right panning, and music. These channels manipulate the sound to be heard and enhance the action as it happens on the screen. To take advantage of Dolby Pro Logic, you should have at least one pair of rear speakers and/or one centre speaker.

You also need to select the appropriate centre mode to enjoy a full effect.

Dolby Surround

Encoding and decoding system of Dolby Surround sound for consumer use. Dolby Surround decodes the extra channels on the Dolby Surround-encoded sound tracks of movie videos and TV programmemed and produces sound effects and echoes that make the action seem to envelop you.

Surround sound

Sound that consists of three elements: direct sound, early reflected sound (early reflections) and reverberative sound (reverberation). The acoustics where you hear the sound affect the way these three sound elements are heard. These sound elements are combined in such a way that you can actually feel the size and the type of a concert hall.

Dolby Digital (AC-3)

This is a new digital surround system proposed to reproduce Dolby SR-D (the 3 dimensional sound system developed for use in movie theatres) in the home. This technology allows you to enjoy the full 5.1 ch soundtrack intended by the filmmaker, in the comfort of your own home.
