Creating Realistic Sound Fields You can use the following surround to reproduce a realistic sound field. • Digital Multichannel Surround -Dolby Digital and DTS Digital Surround GB • Dolby Pro Logic Dolby Digital and DTS Digital Surround To enjoy surround effectively, all the speakers need to be connected and activated. Dolby Digital Used to reproduce multichannel sound tracks of the software encoded with Dolby Digital ( ). Dolby Digital encoding method (discrete 5.1 channel digital audio format)records and digitally compresses the left front channel,right front channel,center channel,left rear channel,right rear channel,and LFE channel signals (total 6 channels,but LFE channel is counted as 0.1 channel.Therefore, LFE is called the 5.1 channel). In addition,Dolby Digital enables stereo rear sounds,and sets the cutoff frequency of the rear treble at 20 kHz,compared to 7 kHz for Dolby Pro Logic.These facts result in better sound quality than Dolby Pro Logic. When the system detects Dolby Digital signals,the DOLBY DIGITAL indicator lights up on the display. DTS Digital Surround Used to reproduce multichannel sound tracks of the software encoded with DTS Digital Surround ( ). DTS Digital Surround is another discrete 5.1 channel digital audio format available on CD,LD, and DVD software. Compared to Dolby Digital,audio compression rate is relatively low. This fact allows DTS Digital Surround format to add breadth and depth to the reproduced sounds.As a result,DTS Digital Surround features natural,solid and clear sound. When the system detects DTS Digital Surround signals, the DTS indicator lights up on the display. Dolby Surround Used to reproduce sound tracks of the VCR tapes encoded with Dolby Surround ( ). This is only used for the sound sources coming through the AUX IN jacks. Dolby Pro Logic and Dolby 3 Stereo Dolby Surround encoding format records the left front channel, right front channel,center channel,and rear channel signals (total 4 channels)into 2 channels. The Dolby Pro Logic decoder built in this system decodes these 2 channel signals into original 4 channel signals - matrix-based multichannel reproduction,and allows you to enjoy a realistic stereo sound in your listening room. When one of Dolby Surround modes is selected,the PRO LOGIC indicator lights up on the display. * Sources recorded in Dolby Surround These are sources in which three or more channels of surround have been recorded as two channels of signals using Dolby Surround encoding technology. Dolby Surround is used for the sound tracks of movies recorded on DVDs, LDs and video cassettes to be played on stereo VCRs, as well as for the stereo broadcast signals of FM radio, TV, satellite broadcasts and cable TV. Decoding these signals with Dolby Pro Logic makes it possible to achieve multi-channel surround playback. The signals can also be played on ordinary stereo equipment, in which case they provide normal stereo sound. Manufactured under license from Dolby Laboratories.
