Product details:
The DSP-A1 Flagship Home Theater Processor/Amp is the most versatile and sophisticated on the market. The DSP-A1 is a 7-channel processor/amplifier providing the finest performance available for music and video sound. 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. The 7 channels are: Left/Right Main, Center, Left/Right Rear Effects, and Left/Right Front Effects. The addition of front effects speakers adds depth to the image. Discrete power transistors rather than IC chips are used in the amplifier section to provide the cleanest sound possible. The amp delivers 110 watts each to the main five channels and 35 watts each to the front effects speakers. Built-in Dolby Digital offers the most advanced and realistic encoded surround sound for movies. The new Dolby Digital system is a fully discrete system providing six channels of sound. Built-in DTSDTS is the latest digital 5.1 channel sound format and is available on laserdiscs, CDs, and will be encoded on DVDs, as well. DTS uses a higher bit-rate than Dolby Digital. A new ASIC, YSS-245, provides Yamaha's exclusive Tri-Field Processing which applies Digital Sound Field Processing technology to Dolby Digital and DTS. Yamaha's exclusive Digital Sound Field Processing for music recreates the acoustic personalities of actual concert halls and other venues, such as the Roxy Theater in Los Angeles, New York's Village Gate, and various concert halls and churches in Europe. Yamaha has designed and employed single function IC chips, called ASICs - Application Specific Integrated Circuits - for the DSP-A1. ASICs are more efficient than multi-function chips and provide the most accurate decoding possible. Yamaha's YSS-249 is an ASIC whose function is decoding Dolby Digital and Dolby Pro Logic. Yamaha's new digital circuitry yields higher resolution sound thanks to its 128x oversampling 24-bit analog-to-digital converters and 8fx oversampli
