YAMAHA DSP-R795

Commentary

An AV amplifier that supports DTS as well as Dolby digital.

It is equipped with YSS-918 which is newly developed LSI which integrated 3 sound field cinema DSP and DSP for DTS / Dolby digital decoder into one chip.
The low-power design minimizes unnecessary heat generation and digital noise, enabling high-precision decoding with 24-bit resolution and high-quality sound field reproduction.

Equipped with 25 sound field programs, you can enjoy movies, music and even games in the appropriate sound field.
Sci-Field program, Sci-Fi, is a sound field program that optimally expresses SF-X movies.

The power amplifier section is equipped with a 5-channel all-discrete power amplifier of the same design.

The power supply section is equipped with a 5.5 kg heavy power transformer and a large-capacity audio capacitor.
In addition, interference between circuits is minimized by thorough analog / digital separation design.

Equipped with an FM/AM tuner.

Input jacks are equipped with audio Route 3 and AV4 systems.
In addition, the digital input is equipped with an optical Route 3 and one coaxial digital input system.

It has an on-screen function and the operation details can be displayed on the TV screen.

It comes with a preset remote controller that stores AV equipment operation codes of major manufacturers.

There are 2 color variations of gold and titanium.

By using the separately sold APD-1, it is possible to play 5.1 channels of Dolby digital compatible LD player.
