“It is so much better in terms of high fidelity, in its purest
sense. It reminded me how Quad retain an almost unique
grip on the concept.” – Noel Keywood, Hi-Fi World
The closest approach...
Since Peter Walker formed the company
in 1936, all Quad products have
loudspeakers of the time, the ESL was free of unwanted
colourations and distortions. This product remained in
production, virtually unchanged, for 28 years.
A decade later in 1967 Quad introduced its first
transistorised amplifiers, the 33 Control Unit and the
303 power amplifier. These amplifiers introduced a new
‘Triples’ output stage that solved all the thermal
instability problems that plagued early transistor
designs. Radical in both circuit design and appearance,
they went on to win a prestigious Design Council Award
in 1969.
displayed an originality in design, born
from a full and proper understanding of
every aspect of sound reproduction. A
world leader in audio amplifier and
electrostatic speaker design, Quad has,
over the years, made a major
contribution to the improvement of
sound quality. This contribution has been recognised by
awards from around the world including the Queen’s
Award for Technological Achievement in 1978.
Quad owners enjoy the confidence of knowing that the
complete system has been engineered to achieve optimal
performance, free from compatibility problems.
The history of Quad is one of technical achievement in
the field of sound reproduction. It is a story that began
with the Quad 1 amplifier, which brought the benefits of
15 years knowledge and experience in professional
audio and industrial products to the task of making the
most accurate domestic audio amplifier of its age.
A few years later, in 1953, the product which set the
standard for amplifiers was the Quad II power amplifier.
This amplifier pioneered the principle of cathode
coupling through the output transformer to reduce
harmonic distortion to almost negligible levels. Such was
its clear superiority that this model remained in
production for 18 years.
Amplifier performance took a further step forward in
1975 with the arrival of the Quad 405 ‘Current
Dumping’ amplifier. This remarkable new circuit
topology remains one of the few truly original amplifier
designs and has featured in Quad products ever since.
For this technology Quad was awarded the ‘Queen’s
Award for Technological Achievement’ in 1978.
In 1981 Quad announced the ESL-63; a full-range
electrostatic loudspeaker based upon two sets of
concentric annular electrodes fed through sequential
delay lines. This patented system produces a sound
pressure pattern identical to the theoretical ideal of a
point source origin. Once again a Quad Electrostatic
loudspeaker became the reference standard around the
world.
These are just some of the highlights from Quad’s
pedigree line of technological achievement. However, it
must always be remembered that Quad has never
indulged in technical ‘one-upmanship’. The technology
is there for a purpose – and that purpose has remained
constant over the years. To reproduce music in a form
that is the closest approach to the original sound.
Three years later, in 1956, Quad demonstrated the first
true full-range electrostatic loudspeaker. This
remarkable product (known later as the ESL-57) used a
virtually mass-less plastic film as a moving diaphragm
between two charged plates. Compared to the

The Quad
99 Series
Quad sound systems have always been able to give their
owners the utmost pleasure and passion when they
listen to music. But now the 99 Series brings more.
Conceived as a fully integrated component system,
there is an assurance of absolute compatibility and the
convenience offered by the high levels of intelligence
exhibited in the control system.
enjoyment they have brought to the most discerning
audiophiles.
The modern design of the 99 Series components has
been developed to dovetail ease of use, style and
elegance with one of the finest sounds available today.
Intelligent control systems are used to create a seamless
link between the various 99 Series components,
allowing complete operation from a single remote
control. Our unique ‘Quad Link’ bus connection system
transfers not only system commands, but also fully
balanced audio signals.
Each component within the 99 Series is one of the
finest examples of such available today. Excessively
over-engineered in every respect – highly specified
transformers, audiophile components, multi-layer
circuit boards and the most advanced software appear
in abundance throughout the system.
The 99 CD-P combined with
the 99 Stereo Power
amplifier and the 11L
Loudspeakers is a perfect
entry to Quad and a
stunning system in every
respect.
With the 99 Series, you are assured exquisite
performance; convenience of use; quality of
construction; enviable support, but most of all, the
pedigree of a company that has built a long-term
reputation on the ability to reproduce music in a manner
that is the closest approach to the original sound.
Our reputation, however, is based upon more than
good engineering and innovation. Quad Hi-Fi units are
famous the world over, not just for their high
specifications and attention to detail, but more for the

The 99 series is timeless in
design and quality. Newer
models such as the multiple
award-winning CD-P and
timeless classics such as the 909
(which is still winning awards to
this day) ensure that when you
choose Quad, you invest in a
piece of audio equipment that
will not only last a lifetime, but
will retain as much value and
relevance for future generations
as well.

Stereo Power Amplifier
Mono Power Amplifier
Quad power amplifiers have always been
amongst the finest in the world. Over the
years, they have earned a reputation for
being ‘straight wires with gain’, because they
neither add nor take anything away from the
original music signal.
Power is something that this 99 Mono
Power Amplifier has in abundance. Into a
nominal 8 Ohm load it delivers well over
150 Watts and a breathtaking 220 Watts into
a 4 Ohm load.
In all other respects, this amplifier is close
to the 99 Stereo Power Amplifier and shares
its technology and topology as well as its
excellent standards of performance.
The 99 Stereo Power Amplifier uses a dual
complementary feedback circuit with
exceptional stability margins to achieve
exemplary performance and an output of
over 80 watts per channel. Overload
recovery is instantaneous and the amplifier
is fully protected against over-driving or
misuse, without resorting to output line
fuses or relays.

FM Tuner
Pre-Amplifier
In many countries FM radio still has the
potential to provide the highest fidelity
programme quality. The Quad 99 FM Tuner
has been designed to make the best use of
that potential.
State of the art performance combined with
unique operating features sets the Quad 99
Pre-Amplifier apart from competing products.
The combination of universal phono-socket
connectors and Quad Link inputs gives the
ability to connect an almost unlimited
number of sources, each with optimal
matching. All inputs, including those for
moving-coil and moving-magnet cartridges,
have adjustable sensitivity.
The UK has gained a world-wide reputation
for the high-quality music broadcasts
transmitted by the BBC, and as a result
British manufacturers such as Quad have
considerable experience in designing tuners
that receive and reproduce music
realistically. The Quad 99 FM Tuner
incorporates that experience in full.
The 99 FM Tuner and 99 CD Player are both
connected to the rest of the system via our
‘Quad Link’ bus system, which combines
complete system control with balanced line
audio transmission. Not only does this
make the entire system remarkably easy to
control, but provides the cleanest audio
signal possible.
This flexibility also extends to the wide
range of precise tone-control adjustments
that can be made. In addition to the usual
high-frequency filter, there are adjustments
for the bass response, and the unique Quad
‘Tilt’ control which skews the entire
frequency response to give a preferred tonal
balance.
The Quad 99 Pre-Amplifier is packed with
technical innovation including noiseless
solid state signal switching and digitally
addressed analogue volume and balance
controls. These track both left and right
channels with a previously unattainable
accuracy of better than 0.1dB.
