Rupert Neve is a legend. His contributions to the elds of audio
recording and production began at the dawn of the era and
continue to this day in the form of microphone preampliers,
equalizers, compressors, and mixing consoles that are the gold
standards of professional audio.
Clearly Mr. Neve is very serious about his sound, so it’s an honor
that he and his company, Rupert Neve Designs, have ocially
recognized Yamaha’s original VCM (Virtual Circuitry Modeling)
technology as being the rst of its kind that is capable of
accurately modeling the rich, expressive analog sound they have
championed for so long. With VCM technology, digital audio is at
last capable of matching analog designs for sonic quality.
VCM, developed by Toshi Kunimoto (“Dr. K”) and his team at Yamaha’s innovative “K’s Lab”
division, is a circuit modeling concept that eectively simulates the most detailed
characteristics of individual circuit components, right down to
capacitors and resistors, resulting in astonishingly realistic
circuit simulations that easily outclass conventional digital
simulations. But accuracy isn’t the only consideration,
musicality is essential as well, and VCM modeling delivers both.
The CL series consoles come equipped with VCM models of the
renowned Neve Portico 5033 equalizer and Portico 5043
compressor/limiter, both developed through close cooperation
with Rupert Neve Designs. A valuable range of other VCM
equalizers, compressors, and studio-quality eects is also
included. You will hear the dierence.
routing so that the most natural, musical sound is achieved.
Another critical part of any audio system is the power supply.
Of course the capacity of the supply is important, but so are
the types of capacitors used, and the grounding must be
engineered to ensure the lowest possible impedance. The
resultant sound is an eminently natural representation of the
input signal, providing an ideal foundation for processing
and eects that will lead to the nal, polished sound.
The challenge begins right from the console’s inputs. In
order to achieve the required level of sound quality,
individual components, power supply, grounding, circuit
layout, mechanical construction, and countless other details
of the initial input stages must be selected and designed
with the utmost care. Listening evaluation becomes an
The full impact of the most advanced digital audio technology
available has been applied throughout the CL series to deliver
natural sound that provides a perfect foundation for the artist’s
and engineer’s imagination. This type of sonic quality cannot be
realized through specications alone. Repeated listening
evaluations and renements by some of the most reliable ears and
respected minds in the business are an indispensable part of the
process. The CL series digital mixing consoles are proof that the
time and eort involved have been well spent.
important part of the development process right from this
rst stage as well. Changing even a single electronic
component can alter the sound in unexpected ways, and the
tiniest variations must be noted and evaluated as
development proceeds. Extreme measures have been taken
to maximize AD and DA conversion performance as well,
right down to making detailed spectral analyses of the
AD/DA master clock and adjusting the FPGA clock signal
Prodigious Quality &
Creative Potential
In creating the best possible sound for a profusion of venues and artist
requirements, sound engineers draw on their experience and imagination
to make a multitude of practical as well as creative decisions. The
engineer’s primary hands-on tool, the mixing console, must be able to
accommodate them all. Of course the bottom line is sound quality, and
this is just one of the areas in which the CL series consoles excel. They also
feature some of the most advanced analog circuitry modeling technology
available to add unprecedented character and shape to the sound as
needed, while maintaining the utmost sonic quality.
