¥ 58,000 (released in 1998)
Commentary
A 5-channel AV amplifier equipped with a Dolby digital decoder.
It is equipped with Cinema DSP engine YSS-908 which is newly developed LSI which integrates 3 sound field cinema DSP and DSP for Dolby digital decoder into one chip.
The low-power design reduces unnecessary heat generation and digital noise, and realizes high-precision decoding with 24-bit resolution and high-quality sound reproduction.
A total of 11 sound field programs are installed.
In addition, we maximize the potential of Dolby Digital by using sound field data exclusively for Dolby Digital such as Digital Movie Theater, which is a three sound field cinema DSP program.
All five channels of the power amplifier are all discrete and designed in the same way.
The power supply section is equipped with a 5.5 kg heavy power transformer and a large-capacity audio capacitor.
In addition, by thoroughly implementing an analog-digital separation design, mutual interference between circuits is eliminated.
Four AV devices and four audio devices can be connected.
In addition, two optical and one coaxial digital inputs are installed.
Equipped with a 5.1 channel external input terminal, it is also compatible with multi-channel output of next generation audio.
Equipped with an input signal method automatic determination function, it automatically determines the type of input source (Dolby Digital / PCM).
Comes with a preset remote including Yamaha products A preset remote av equipment of major manufacturers including Yamaha products.
There are 2 color variations of titanium color and gold.
