DIGITAL (coaxial) 11 SURROUND EFFECTS SURROUND SOUND EFFECTS The DD81 can play five different types of surround sound depending on the program source and the type of audio connection. The following section describes the different types of surround sound. DOLBY PRO LOGIC Surround Dolby Pro Logic is a surround format that uses an analog audio signal. It is the audio format used for most video cassette tapes and many television broadcasts over-the-air and through cable and satellite boxes. Although not normally used for radio broadcasts and music on CD's and cassette tapes, the Dolby Pro Logic surround sound function can be used for these sources when they are broadcast or recorded in stereo. Dolby Pro Logic requires a stereo audio signal to operate ­ it does not work with mono audio signals. Dolby Pro Logic offers 5 channels of sound: 1) Front left channel 2) Front right channel 3) Center channel 4) Rear channel (2 speakers) The DD81 Dolby Pro Logic surround sound function operates when: An optional stereo television, Hi-Fi VCR or DVD player is connected to the audio inputs on the rear of the DD81. The program source (tape, disc or broadcast) is recorded in Dolby Pro Logic Surround Sound . And, the digital input selector is properly set according to the connection made between the component and the DD81. DOLBY DIGITAL Surround Dolby Digital is a surround sound format that uses a digital audio signal. It is the audio format used for most Digital Video Discs (DVD) and for digital high definition television broadcasts over-the-air and through digital cable and satellite boxes. Federal law requires all television broadcasts to be made in high definition format by 2006. Therefore, Dolby Digital will become the dominant surround sound format in the future. This DD81 music system is ready when you are for adding digital TV and other digital audio/video components. Dolby Digital recordings and broadcasts have 6 channels of sound for the most authentic theater experience. These six channels are sometimes referred to as 5. 1 channels ­ five full-range and one low frequency effects (LFE) channel. The LFE channel has special low frequencies that can be played back through an optional powered subwoofer. The digital signals used in Dolby Digital provide the most accurate sound reproduction available. 1) Front left channel 2) Front right channel 3) Center channel 4) Left rear surround channel 5) Right rear surround channel 6) Low frequency channel The DD81 built-in, Dolby Digital surround sound processor will only operate when: An optional digital audio/video component such as a DVD player, HDTV, digital cable or digital satellite box is connected to the DD81.
