1.0 The History
Since the invention of the phonograph, generations of investigators and engineers
have worked to make perfect the quality of audio record and playback.
The power spring of these efforts is and was the dream of human beings to hold
tight for ever irretrievable moments and, particularly, impressive musical experiences,
and thus to make repeatable, so to say „live to hear“ again.
It's the goal to capture, to conserve, and to maintain for the posterity the
fascination of the instant underwent via our senses. This fascination shall then
be able to be echoed as really as possible at any time independently of location,
time, and room.
The existing exhibits of painting, of photography, but not least of the modern
technical media like movie, television, and video, are witnesses of this desire to
„copy“ continuously these original, moment-bound events. With the invention
of digital transformation and storage of tones and sounds one has come nearer
to this goal by a formidable step.
Revox - since the foundation more than 50 years ago devoted to the storage and
playback of sounds in a quality as high as possible - in recent years has taken
care of the limb of the chain supposed as the weakest, in the most intensive and
successful way: the loudspeaker.
In long-years‘ most intensive developmental work a system has arisen which opens
a completely new dimension of sound reproduction. In cooperation with sound
engineers from all over the world and by investments in an amount of millions it
has been done to create the most exact speaker.
With the digital-active loudspeakersystems by Revox are abolished all faults
hitherto well-known and relevant for playback of music as well as the weaknesses
of conventional active and passive speakers inherent in construction. The intelligent
compensations and controls are performed digitally and will enable this system
to render any kind of music in an absolutely unadulterated way and in the
best sense „naturally“.
By this digital signal processing Revox fi nally succeeded in completely compensating
disturbing time delays. The fact that there are no completely phase-independent
speaker chassis has prompted our engineers to make remedies once again. The
result of this extensive work is the Revox patented circuitry principle of the negative
output impedance for all speakers involved, which cares for correct rendering of
pulses. This ensures an extremely dynamic and 'live' feeling of the music as close
as possible to the original and the result is a perfect sound impression within the
whole transmission range. The capability of exactly tracing natural timbres of
voices and instruments is the absolutely unsurpassed force of the digital-active
speaker systems by Revox.
The matter of course and the sovereignty in transforming any sound event
into „acoustic experience“ are the sources of the intrinsic fascination of these
„modifi ers“.
They incorruptibly, neutrally, and authentically transform the digital audio signals
offered to them in acoustic vibrations. These are characterized by unsurpassed
precision and are perceived - at least under living room conditions - in nearly
unlimited dynamics.
We experience the nearly perfect illusion of the original happening.
The circle closes!
The capability of experiencing again one-time musical events true to the original
in the own four walls has a name:
Revox digital-active speaker systems.

2.1 Scala 3.6 - Re-defi ning high-end
The slim Scala 3.6 stands for legendary Swiss quality and combines refined
technology with elegant, timeless design. Audiophiles who are tired of their fl ats
looking like sound studios will love these speakers. In short: a totally new dimension
of listening for you to discover. You can directly connect a digital source to the
Scala 3.6 as the speakers are based on digital signal processing. Therefore, all you
need to listen to music is, for example, a CD player with digital output. The
Scala 3.6 digital loudspeaker marks the beginning of a new era in the history
of perfect music reproduction. Our engineers have completely eliminated systemrelated loudspeaker faults by consistently and comprehensively implementing
digital technology.
Each loudspeaker houses three 130 W power amplifi ers and six drivers. Four
paralleled long throw woofers, a midrange speaker, and a treble dome ensure
an impressive sound pressure level.
