Centre mode

Setting of speakers to enhance Dolby Pro Logic Surround mode. To obtain the best possible surround sound, select one of the following four centre modes according to your speaker system.

• NORMAL mode

Select NORMAL mode if you have front

and rear speakers and a small centre

speaker. Since a small speaker cannot

produce enough bass, the bass sound of

the centre channel is output from the front

• 3 CH LOGIC mode

Select 3 CH LOGIC mode if you have front and centre speakers but no rear speaker. The sound of the rear channel is output from the front speakers to let you experience some of the surround sound without using rear speakers.

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 programmes and produces sound effects and echoes that make the action seem to envelop you.

The processor offers Dolby Surround as one of the pre-programmed sound fields. If you have rear or centre speaker(s), we recommend that you customize the Dolby Surround sound field by selecting the appropriate centre mode to take advantage of Dolby Pro Logic Surround sound.

(reverberation). The acoustics where you hear	Rear (L, R)
