Introduced in the Yamaha A3090 performance parameters are as follows: Dolby AC-3 decoder parts, uses YAMAHA's own YSS249 chip, this chip to 24bit operations, very high accuracy of information transmission rates of up to 640Kbps. DSP sound field and EQ feature, also YSS2l4 DSP chip designed by YAMAHA is finished, this chip also 24bit operations, YSS214 was used in the sources, communications and other specialized equipment. DTS parts using a separate circuit boards, located on top of digital circuits, cover with a thin metal plate shielding, apart from isolating noise function, but also enhance heat dissipation effect. Motorol company DSP56009 DTS decoding chip, this chip to 24bit operations, operation speed up to 93Mhz. A/d converter IC is the latest Asahi Kasei products AK5391, 24bit L28 times for sampling,

Dynamic range of 113dB,SN to 113dB;D/A conversion IC's Asahi Seiki products AK4324.
