It is QUANTEC's aim to present the
sound engineer with the most comprehensive tool
possible for influencing the diverse parameters
relating to room acoustics. Conceptual ideas pertaining
to acoustical size and capacity of any selected
space may be accurately reproduced via the clearly
defined acoustical parameters of the reverberating
signal. Whether employed for film sound dubbing,
theater, or musical productions, the QRS serves
all the demands of any given room acoustic simulation.
It enriches the typically sound-insulated character
of a commentator's or speaker's chamber in the process
of film synchronisation and creates the natural
sound concomitant to the staging of the film.
This sophisticated tool is completely
stereophonic, and the first reflection, which may
be separately adjusted in level and delay time,
appears on an opposite side of the stereo image.
Besides being able to define the spatial volume
in cubic meters, further parameters available are
the reverberation time and its high- and low frequency
deviations, as well as the ability to define both
level and time delay of the reverberation effect
at will and in fine increments. All eight parameters
of each adjustment are simultaneously displayed
on the front panel of the mainframe as weIl as on
the remote-control unit connected to it.
The built-in nonvolatile memory
fixes up to 64 parameter combinations of which several
are pre-programmed by the manufacturer, the largest
portion being left open to the operater's discretion.
The special "Enhance-Programme" provides new dimensions
in stage- and film productions. The "Freeze-Effect"
(i.e. infinite decay time) enables continous overlapping,
or addition of successive entries, and allows for
instantaneous building up of choral effects as well
as the creation of impressive sound clusters. The
QRS corresponds to the very latest demands placed
upon operational efficiency, audio quality, and
reproduction as well as technical conception to
meet the standard of professional broadcast utilization
and recording industry.
Display and Programming
The input and output levels are displayed by a
total of six LED bar graphs spanning the intire
dynamic range of -78dB to +12dB. The clearly legible
LED display panel provides instant information concerning
all adjustable parameters. Accurate and rapid programming
and operation are guaranteed by sensitive touch
buttons and a comprehensively elaborated logic system.
To programme a given value, a pair of touch buttons
corresponds to each indicator, whereby the desired
parameter is selected by a quick touch of the proper
button, thereby also allowing the so chosen parameter
to be further adjusted until the following one is
actuated in its turn. This readiness for adjustment
is indicated by a short, intermittent flashing of
the corresponding LED readout. Upon having chosen
a particular value, adjustments may either be accomplished
through further tapping of the set of buffons or
via a centrally positioned, rotating knob.
The memory section is devided into 8 files of 8
locations and enables a clear definition of parts
of memory, e.g. for different users. By means of
an carefully designed operational logic, it is possible
to transfer parameter combinations within a file
and from file to file, in order to reorganize the
stored programmes. A safety circuit prevents unintended
erasing or altering of memory contents. Of course
all stored programmes are safe in case of mains
faults and long periods without power supply.
Technical Concept and Connections
The QRS, via its computerized systems, reproduces
more than 10000 reflections per second, constituting
the basis of pure and bounce-free reverberation.
Due to a completely new conception of the antialiasing
filters an almost total subduing of the often-discussed
"roaring" and "ringing" of conventional filters
is accomplished. High-efficient RF-lowpass filters
at the inputs of the A/D-converters eliminate all
problems of RF demodulation effects.
The QRS has a total of six connections comprising
XLR plugs: 2 inputs (left and right) and 4 outputs.
The QRS is provided with XLR connectors: Two inputs
(stereo) and four non-correlating reverb outputs
(quadro). In addition outputs 1 + 2 contain the
mix with the first reflections appearing on the
opposite side.
Both inputs and outputs are balanced and isolated
from ground by optocouplers.
Any room anywhere
Acoustics
- a new element in the composing art of music
The Quantec room simulator now makes
the construction and manipulation of acoustics a
simple reality. Acoustics are no longer bound by
the specific configuration of a room, but can be
used to emphasize a scene, enhance or improve a
sound or enrich a musical composition.
Quantec heralds a new era: A small
revolution in acoustic versatility. Any sound environment
is obtainable at the push of a button, from the
tiniest drop of water in a deep well to the infinity
of the ocean. From the soft echo of a flute in the
vast nave of a church, to the rumbling of a thunderstorm
in a fish bowl.
In much the same way as a painter
uses different shading details and texture to create
atmosphere and impression on canvas, acoustics can
sharply influence simple sounds, create a mood or
atmosphere or totally change the listeners perception
and experience.
By mixing acoustic elements, or
using one of the infinite and variable environments,
the composer's actual intention and the music's
special qualities become a vivid musical experience.
Acoustic imaginings or aural halucinations
are easily attainable. One can construct genuine
sounds in completely impossible rooms. Experience
the acoustics of a rain barrel, the echo of the
Grand Canyon, place music where it has never been
before in an environment that suits its mood and
increases it's impact.
The Quantec gives you flexibility
that has only just become possible, capabilities
that apply exactly to film and TV scoring. This
is a rack mounted acoustic environment simulator
that gives music its own space and you all the time
and help to change it.
