Gregg Loewen **********This a sealed Sony SDP-E800 Preamp DD Processor with built in AC-3 Demodulator. This unit will not only provide you with LD AC-3 demodulation but also add an additional 3 digital inputs to your system. **********The Sony SDP-E800 Dolby Digital Processor represents a remarkable value for converting your system to the latest surround sound technology. It uses full 24-bit processing and Sony's proprietary hybrid pulse digital-to-analog converters for clean, accurate sound. It senses the appropriate surround mode for the source you've selected and switches automatically. Sony builds in its Digital Cinema Sound System, which some listeners will find enhances the theater experience by simulating film studio dubbing stages. For the fullest enjoyment of Dolby Digital, Sony allows you to adjust which speakers receive the lowest bass, and the frequency at which the adapter directs the bass to the subwoofer(s) or low frequency effects speaker. The true digital volume control does not degrade sound quality, as some poorly designed digital volume controls might. Best of all, a computer software-like set-up "wizard" guides you through installation. For use with Receivers or Amplifiers equipped with 5.1-channel inputs Dolby Digital and Dolby Pro Logic decoding 24-bit digital processing Six Sound Modes with 26 customizable Sound Fields Digital Cinema Sound system with Cinema Studio Modes Virtual 3D processing Hybrid Pulse D/A Converters Individual speaker adjustment and setup Speaker Size Setup with Bass Redirection Digital Crossover Control Three Optical Digital Inputs One Coaxial Digital Input One Dolby Digital RF Input for Laserdisc players Karaoke 5 Digital Video Inputs: 3 analog, 2 Digital Full function Remote Control and manual **********This processor allows you to connect up to 3 digital audio source components, such as a DVD player, a laserdisc player with AC-3 RF output, a CD player, and a minidisc or DAT deck. There are 3 optical inputs, 1 coaxial digital input, and 1 AC-3 RF input. There is one optical digital output so that the digital signal may be input to a minidisc or DAT deck. There is a video input for each digital input that is switched with the audio signal. There is also a single analog audio input. The decoded digital signal is output to your multi-channel amplifier via 6 discrete channels (left, center, right, left rear, right rear, and subwoofer). There are 26 customizable sound fields that let you simulate the sound of anything from a stadium, to a movie theater, to an opera house, and much much more. And best of all, it is easy to operate.
