Commentary
5 chAV amplifiers equipped with CINE-DSP and FM/AM tuners.
In addition to digitizing the Dolby Pro Logic decoder, we have adopted the CINE-DSP processing that brings new effects and the Front Mic playback method that plays back the front-side effect signal from the L and R speakers to realize 5-channel theater surround sound.
A newly developed original LSI (YSS developed original LSI (YSS-203) that integrates a digital Dolby Prologic decoder and a DSP processor including Double 4 chDSP processing. It achieves accurate and stable operation by digitally processing a series of prologic decoding operations including auto input balance, directional enhancement, and deformed B noise reduction.
It is also equipped with the Dolby ProLogic "Enhanced" mode, which simulates the sound system of a 35 mm movie theater with a large number of surround speakers by converting the surround side into a diffuse surround sound field that expands and surrounds the listener by processing the surround signal after the digital prologic decoding into 4 chDSP.
The operation mode of the YSS 203 can be switched to concentrate its power on DSP processing. This enables more processing of reflected sound, enabling sound reproduction of rock concerts and concert halls.
You can also process Mono Movies and Concert Videos.
In the power amplifier section, 3 channels on the front side have the same discrete configuration, and a 5-channel amplifier with a rear amplifier is also provided.
The power supply section uses an 8 kg large-capacity power transformer.
A 40-station preset type FM/AM tuner is mounted.
Equipped with a sleep timer function.
A learning remote controller is included.
There were 2 types, titanium color and BlackCar color.
