Redefining audio for luxury home cinema
Professional audio
for the home
Look closely at a movie poster or the credits of a Hollywood picture
and you’ll see three important words: Datasat Digital Sound. It’s
a mark of assurance that the film delivers an outstanding Digital
Surround Sound experience to cinema audiences throughout the
world. Now, Datasat Digital Entertainment brings the same
experience and professional audio quality to luxury home cinema.
Since 1993, we’ve been pioneering Digital Surround Sound. We began as part of DTS before its
cinema division became Datasat Digital Entertainment in 2008. We introduced millions of moviegoers
to Digital 5.1 Surround Sound with the release of Jurassic Park. Since then, we’ve continually
innovated to provide a better, richer and more realistic audio experience for professional cinema.
Our sound technology is in daily use by over 30,000 cinema screens across five continents. When
Barco created the world’s first commercially available 3D sound system for cinemas, they placed our
audio processing technology at its heart. Today, the Datasat AP20 is rapidly becoming the audio
processor of choice for high quality cinema sound due to its advanced features, audio quality,
reliability and precise reproduction of both digital and analog sound.
Our professional audio products are developed by sound engineers for sound engineers. We may be
sound engineers but we are audiophiles too. We have ensured our home cinema products are created
by audiophiles for audiophiles. With one key difference. Ours are the only home cinema audio systems
developed from the same technology platform as our award-winning professional cinema solutions.
The Datasat RS20i delivers a new dimension in two channel and surround sound excellence to luxury
home cinema. The audio is transparent and true-to-source to ensure the listening experience is as
good or even better than the best cinema. Designed to complement the Datasat RS20i, the Datasat
range of amplifiers deliver extremely accurate and refined voice and music reproduction in the most
demanding environments.
Over 30,000 cinemas worldwide use our
digital audio systems. Today we work with
top exhibitors to keep Datasat at the
forefront of digital sound.
T here have been more than 14,000 movie
releases worldwide – including 2,500
Hollywood titles – that feature our sound
S ince 1993, our team has released 17
products for professional cinema and
studios including audio processors, audio
playback units, extended surround units
and media playback systems.
Our digital sound technology was
recognised by an Academy Award in 1996.
Our team was presented with the Technical
Award in the Scientific and Engineering
Category for the design and development
of the DTS digital sound system – which is
now called Datasat Digital Sound.
Designed for the discerning listener
Datasat RS20i
The Datasat RS20i is the most versatile, customisable and featurerich audio processor available today for luxury home cinema. It
introduces a new level of crystal clear, highly realistic two
channel and surround sound audio that makes the listener feel
that they are right there in the middle of the action.
Designed by the same Datasat team responsible for the Datasat AP20 professional audio processor, the
circuitry design and audio quality of the Datasat RS20i is second to none. It comes with many features not
previously seen in high end home audio processors including Dirac Live® advanced room optimisation and
correction, 20 memory profile settings, stackable multiple EQs and extensive automation controls.
The Datasat RS20i delivers a level of refined, true-to-source audio above competitive processors.
Soundtracks sound like they are being played from the original mixing desk and music comes alive.
The inclusion of Dirac Live® means rooms can be optimised so that sound is delivered with pinpoint
accuracy and improved detail.
With 16 channels of digital audio, the Datasat RS20i supports all sound formats available today
including two channel, 5.1, 7.1 and 9.1 and will even support 11.1, 12.4, 14.2 and anything in
between. Features such as HDMI v1.4a mean it can also seamlessly handle 3D video content. In
addition, three expansion slots ensure that the Datasat RS20i can support exciting new audio
developments as they happen.
Audio is tuned to create the most natural and immersive listening experience for the individual
listener. A global delay on the input means that the audio can be offset to adjust for sync. Individual
channel delays allow for adjustment of speakers for time alignment in full range or active crossover
applications. It also means that speakers in the sound system can be positioned so that they are
perfectly balanced with the acoustic behaviours of the room.
This power and flexibility is matched by stunning good looks. With front panel and chassis designed
by Neal Feay Company, an award-winning designer of consumer electronics, the Datasat RS20i
makes an attractive component of any luxury home entertainment system.

Dirac Live®
Making the entire room a sweet spot
Every room is different. In addition, traditional home entertainment
systems deliver audio to a limited sweet spot at a central listening
location, Dirac Live® allows the Datasat RS20i to deliver
outstanding audio quality to the entire listening environment.
Dirac Live® is state-of-the-art digital room correction technology that optimises the sound both in
terms of the impulse response as well as the stationary frequency response. The result is
substantially improved musical staging, clarity, voice intelligibility, and a deeper and tighter bass,
not just in a small sweet spot but in the entire listening environment.
By digitally optimising the audio signal prior to sending it to the amplifiers, and by measuring the output from
each speaker of the audio system, sound interference and distortion can be overcome. This allows
the Datasat RS20i to produce much more transparent and true-to-source sound in even the toughest of
operating environments.
Key Features
Increased Musical Clarity And
Voice Intelligibility
By digitally optimising the output from
each speaker, so that it is perfectly
adjusted to the acoustic behaviour
of the listening environment, a much
more transparent and realistic sound
can be delivered. Voice intelligibility is
improved and music becomes clearer.
True Impulse Response
Dirac Live® is unique to the
marketplace in that it provides true
working impulse response correction
as measured over larger listening
regions. This impulse response is
critical for multichannel and stereo
perception. Localisation and stereo
hearing, in general, depend on the
similarity between and the quality of
the channel impulse responses. Dirac
Live® improves the precision and the
clarity of the audio imaging.
Mixed Phase Correction
Restored Sound Stage
Dirac’s mixed-phase filter technology
provides the highest performance
available. Loudspeakers measured
in rooms are mixed-phase and
consequently only a mixed-phase
correction can restore the intended
impulse response. Room correction
systems that only provide minimumphase or linear-phase correction fail to
improve aspects which determine the
perceived localisation and clarity of a
sound event.
Dirac Live® restores the sound stage
so that the localisation of sound events
become much more detailed. Since stereo
and multi-channel perception depends
crucially on the similarity, or correlation,
between the signals at the left and right
ears, which in turn is determined by the
impulse responses of the signal paths,
only true mixed-phase impulse response
correction can improve the spatial
perception of a sound reproduction. Dirac
Live® is the solution to achieve this in
any size listening space.
A Deeper And Tighter Bass
Reduced Listening Fatigue
Acoustic room modes distort the
character of the bass. Loudspeakers
continue to ring even after a bass punch
has been delivered due to mechanical
restrictions. Dirac Live® effectively
prepares the loudspeaker for the
sound that is coming and reduces
the settling time of the loudspeaker,
thereby achieving a much tighter bass.
By adjusting the speaker outputs to
the room modes, the character of the
bass is restored to that intended on
the recording. The result is a tighter,
deeper and more defined low end.
Time-domain distortions, caused by
diffraction, cross-overs, and early
reflections, make it difficult for our
brains to interpret the sound. A smooth
frequency response and an aligned
phase response make the sound more
natural and prevent listening fatigue
during prolonged listening sessions.
With the unique phase response
correction and magnitude response
optimisation of Dirac Live®, listening
becomes effortless and brings you one
significant step closer to reality.
Magnitude Response
Dirac’s patented methods offer just
the right resolution. Based not only on
an average response, the stationary
frequency response correction looks
at the variations between different
measurement positions and carefully
makes a correction whose level of
detail depends on the frequencydependent spatial variations.
