It creates a true movie theater experience in the home by developing independent enhanced sound fields for the front signals as well as for left and right surround. TRI-FIELD PROCESSING A new ASIC, YSS-245, provides Yamaha's exclusive Tri-Field Processing which applies Digital Sound Field Processing technology to Dolby Digital and DTS. DTS uses a higher bit-rate than Dolby Digital. BUILT-IN DTS DTS is the latest digital 5.1 channel sound format and is available on laserdiscs, CDs, and will be encoded on DVDs, as well. It is called a 5.1 channel system since five channels are full-frequency, and the sixth is a low frequency effects channel. The new Dolby Digital system is a fully discrete system providing six channels of sound. BUILT-IN DOLBY DIGITAL The most advanced and realistic encoded surround sound for movies. The amp delivers 110 watts each to the main five channels and 35 watts each to the front effects speakers.
DISCRETE POWER TRANSISTORS Discrete power transistors rather than IC chips are used in the amplifier section to provide the cleanest sound possible. The addition of front effects speakers adds depth to the image. The 7 channels are: Left/Right Main, Center, Left/Right Rear Effects, and Left/Right Front Effects. The processor provides 42 possible programs including Dolby Digital, DTS, Dolby Pro Logic, Yamaha's proprietary Tri-Field Processing, Cinema DSP, and Hi-Fi Digital Sound Field Processing.
