YAMAHA DSP-R995

Commentary

This AV amplifier is compatible with DTS / Dolby digital and has various functions such as digital input, RF demodulator, S terminal, etc.

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.

With 25 sound field programs, you can enjoy the sound field appropriate for each source, such as movies, music and games.
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 power transformer and a large-capacity audio capacitor. In addition, interference between circuits is suppressed by thorough analog-digital separation design, and superior reproduction capability is obtained.

It has an on-screen function so that the operation contents can be displayed on the TV screen.

Equipped with an RF demodulator function that enables direct playback of Dolby digital compatible LDs.

A total of eight input terminals, AV Line 5 and audio Route 3, are installed.
All video input / output terminals are equipped with S terminals, and four optical and one coaxial digital input terminals and one optical output terminal are installed.

All speaker terminals are equipped with large speaker terminals.

Equipped with an FM/AM tuner.

Equipped with a 5.1 channel external input terminal, it is compatible with next-generation multi-channel audio such as DVD-Audio.

A learning remote controller is included.
This remote control allows you to select the sound field and adjust various parameters.
