Basic Functions

Selecting the surround sound mode

IMPORTANT!

–For proper surround sound, make sure you have followed the “Connections” and “Preparations” procedures fully.

–The centre and surround speakers only operate when the system is set to surround sound mode and the source material being played is recorded or broadcast in Dolby Digital, DTS or Dolby Pro Logic surround sound.

–Stereo broadcasts or recordings will produce some surround channel effects when played in a surround mode. However, mono sources will not produce any sound from the surround speakers.

●Press SURROUND to select surround or stereo mode. ➜ The availability of the various surround sound modes depend on the number of speakers used and the incoming sound information available on the disc.The available output modes are shown below.

Matrix

A new surround playback system that delivers amazingly rich and convincing five-channel surround outputs (front left/right, centre, surround left/right).

VSS (Virtual Surround Sound)

The ProLogic MPEG or Dolby Digital surround channel is processed by a ‘virtualiser’ DSP to add surround effect from just the two front speakers.

Stereo

All sound is reproduced and played through the front left and right speakers. This enables standard stereo reproduction.

Selecting the digital sound effect

The digital sound effects allow you to select from various pre-set modes that control the frequency bands of sound to optimise certain musical styles. It greatly enhances the excitement and enjoyment of your favourite music.

E n g l i s h

Dolby Digital Surround

Dolby Digital (also known as AC-3 or Dolby 5.1) and MPEG Multichannel delivers a realistic and dynamic sound similar to theatre and cinema. It requires connection of all five speakers (front left/right, centre, surround left/right) and subwoofer for correct Dolby Digital Surround sound reproduction. Each channel plays its own unique role in providing the right sound. Front left, centre and right join two surround speakers to reproduce high, mid and bass frequencies in five full-range channels of surround. Bass rumble, explosions and low frequency effects you feel are delivered through the subwoofer. A large number of DVD discs have been recorded in Dolby Digital Surround.

DTS Surround

The DTS Surround is a cinema surround sound format that offers superior digital audio performance. DTS offers more clarity and definition especially for higher tones. The better sound quality is a result of the limited sound compression (3:1 instead of 11:1 for Dolby Digital) and the 20-bit resolution.

Dolby Pro Logic Surround

The Dolby Pro Logic Surround system is a specially encoded two-channel analogue format that will produce sound through four speaker channels (front left, centre, front right, mono surround) when a Dolby Pro Logic Decoder is used. It is also compatible with stereo systems but the user will only have two-channel (front left & right) of sound.

●Press SOUND repeatedly to select the available sound effect.
