YAMAHA DSP-2000
¥ 138,000 (around 1992)
Commentary
Based on the AVX 2000 DSP, this is a DSP processor amplifier with integrated processor and 5 ch effect amplifier.
By adding DSP 2000 to your 2 ch system, you can enjoy 7 chCINE DSP.
The Yamaha CINE-DSP (Combination for Intelligent & Natural Effect) incorporated in the DSP 2000 combines Dolby Pro Logic or a directional enhancement circuit with an original Yamaha DSP that creates reflected sound based on measured data. After accurate decoding by Dolby Pro Logic, the sound effect is restored by double four chDSP processing.
It is equipped with AV-DSP sound fields of 4 modes and 7 programs such as "Enhanced" and "MOVIE THEATER" which reproduce sound fields of 35 mm and 70 mm theaters by combined processing of Dolby Pro Logic and Yamaha DSP, "CONCERT VIDEO" and "TV THEATER" which reproduce image software of TV and music video with realistic feeling by combined processing of directional enhancement circuit and Yamaha DSP, and a total of 12 modes and 23 programs such as "CONCERT HALL" and "JAZZ CLUB" including HiFi-DSP for music source.
By using LSI for the sound field processing section, space is reduced and the quality of the amplifier section is improved.
The amplifier section uses an all-discrete configuration, and the center amplifier, which is especially important, uses balanced amplification with two discrete amplifiers to achieve low distortion and high output.
The center channel is equipped with a 5-band GEQ that can adjust the tone with the main speaker.
A super-woofer terminal is installed to provide a more realistic low-frequency playback.
In addition to the monaural output terminal, the split terminal is also equipped for the output terminal. Center and surround output can be divided to right and left, and L/R output can be added. The band is 200 Hz or less, + 10 dB to -50dB, and MUTE can be controlled by remote control in 1 dB steps.
You can use the front amplifier as the main amplifier by changing the jumper pin connection on the rear panel.
If you use the front mix switch in this case, you can enjoy the CINEDSP sound field of the front mix system with five speakers using only one DSP 2000.
Wireless remote control is included.
There were 2 types, titanium color and BlackCar color.
