Yamaha Natural Sound AV Amplifier DSP-A1 - Gold Excellent Condition !!! The unit is in excellent condition & 100% functional. Comes with remote. Specs: This is a flagship Yamaha A/V amplifier that supports DTS as well as Dolby Digital and Dolby Pro Logic. From mono / stereo to Dolby Pro Logic, Dolby Digital and DTS Digital Surround, all the home sound formats of the day are supported.Also, by using dedicated sound field data for each format, we have achieved sound field effects that take advantage of the characteristics of each format. The processing section, which is in charge of processing sound field programs, is integrated on a single board. This board is equipped with DTS / Dolby Digital digital input terminals and A/D and D/A converters. This board is completely separated from analog signals, including the digital arithmetic section, and realizes high precision and high quality sound field processing.The Dolby Digital Decoder is equipped with Yamahas original 24-bit ASIC LSI YSS-249, designed with an emphasis on high-speed and high-precision processing. With 24-bit precision, high-quality Dolby Digital Playback is possible.The yamaha YSS 214 LSI is used for sound field processing. In addition to DSP functions, the YSS 214 also includes digital equalizer functions such as cinema EQ and center GEQ. The A/D converter uses a 128 times oversampling delta-sigma 24bitA/D converter.An 8 x oversampling delta-sigma 24bitD/A converter is used for all channel D/A converters.A switched capacitor filter and a continuous filter are used for the post-filter, providing excellent jitter resistance and reproducibility of very small signals. The power amplifier section is equipped with an all-discrete 7-channel power amplifier.The front L/R, center and rear units use power amplifiers of the same power and quality, and all achieve a maximum practical output of 150W. In addition, an amplifier with a maximum practical output of 45Wx2 is used for the Cinema DSPs unique front effect.The power supply section is equipped with a 8.5 kg heavy weight low-impedance power transformer and a 50 mm diameter x 90 mm high block capacitor for high-quality audio. Metal plate resistors for high-quality audio in a ceramic case, metalized ????? film capacitors for copper-lead, and other parts and internal wiring materials are made with particular attention to high-quality sound reproduction.It uses an 8-string master volume that can adjust the volume of 8 channels including LFE (subwoofer).Equipped with a 42-position cinema DSP/HiFi DSP sound field program for a wide range of sources.
