Digital Sound Fields (DSP)
Technological advances in sound reproduction over the last 30 years have enhanced the listening experience with improved clarity,
precision, and power. However, something has been missing: the atmosphere and acoustic ambience of the public venue. Our Yamaha
engineers have extensively researched the nature of sound acoustics and the way sound reflects inside a room. We sent these engineers
to famous theaters and concert halls around the world to measure the acoustics of those venues with sophisticated microphones. The
data they collected is used to recreate these environments in digital sound fields. Some of these digital sound fields have been created
using data measured at the original venue; others have been created from combinations of data to form unique environments for specific
purposes. Some have been designed especially for music, and others especially for movies. Of course, this only solves half of the
problem. Because these engineers have no way of knowing the acoustics of your entertainment room, we have made it possible for you
to adjust the various parameters of this data to tailor each virtual venue to your taste. You can use these sound fields to enhance any
source and in combination with any of the following surround sound technologies.
CINEMA-DSP: Dolby D DSP and DTS + DSP
The Dolby Digital system and DTS system show their full capability in large movie theaters, because feature film soundtracks
are designed to be reproduced in such environments. It is difficult to recreate a sound environment similar to a movie theater in
your entertainment room because of the room size, wall materials, and the number of speakers in your entertainment system.
Yamaha DSP technology makes it possible for you to enjoy nearly the same sound experience as that of a large movie theater in
your entertainment room by compensating for lack of presence and dynamics in your entertainment room with Yamaha's original
digital sound fields combined with Dolby Digital or DTS soundtracks.
Virtual CINEMA DSP and HP CINEMA DSP
Yamaha developed the Virtual CINEMA DSP algorithm which allows you to experience the virtual sound fields without
surround speakers. This makes it possible for the DSP-AX1 to produce a full surround sound catering to the number of speakers
you have. The DSP-AX1 also has an HP (Headphones) CINEMA DSP algorithm which is achieved by the crosstalk processing
applying the precise Head Related Transfer Function. You can therefore enjoy listening to the CINEMA DSP soundfields on
headphones.
Multi-function remote control
The remote control can operate other audio-video components once you program the remote control using the manufacturer code and
Learn feature.
Various Input and Output Jacks
The DSP-AX1 has various output jacks for audio and video signals as well as a digital recording output jack. Many input jacks are also
available for connection to multiple audio-video sources. All the video inputs and outputs have S-video jacks in addition to standard
composite video jacks for improved video picture quality. Component video input and output jacks are also available to deliver the
excellent video signals from DVD players and other high quality video sources. The coaxial and optical digital signal jacks (provided
for direct transmission of digital signals) automatically detect Dolby Digital, DTS, and PCM signals. A demodulator circuit is built into
the Dolby Digital RF input so you can connect it directly to the Dolby Digital RF signal output on your LD player. Additionally, there
are six audio inputs for disscrete multichannel reproduction from an external decoder.
The DSP-AX1 also comes with a monaural subwoofer jack and split subwoofer jacks which can reproduce delicate but powerful low
frequency effects.

Custom installation facility
You can make up a multi-room audio-video system with this unit. With this feature, you can set this unit to reproduce separate input
sources in the main room and in a second (ZONE 2) room using the supplied remote control in the second room.
