Special Design Philosophies
Perreaux has been designing and manufacturing only the highest quality audio
componentry for more than a quarter of a century. Technology has continued to
evolve rapidly over that time and our knowledge and application of design,
materials and manufacturing techniques has advanced in tandem with this.
Today’s Perreaux range comes closer to fulfilling our shared vision than at any
other time in the past.
To follow is a discussion on some of Perreaux design philosophies that have
been incorporated into the entire range.
Minimalist Leading British architect, John Pawson, writes:
Design
“The Minimum can be defined as the perfection that an object
achieves when it is no longer possible to improve it by subtraction.
This is the quality that an object has when every component, every
detail, and every junction has been reduced or condensed to the
essentials. It is the result of the omission of the inessentials”.
Perreaux has historically embraced the minimalist ethic from an audio design
perspective only. The concept of “less equating to more” has been at the heart
of all Perreaux audio designs for more than a quarter of a century.
Minimalist Electronics
We wish to maximise the quality of your listening pleasure by keeping the
componentry and signal path as uncluttered, short and clean possible. All
components in the signal path, even those of the highest quality have an effect
on the signal, thereby altering the quality of the reproduction in some way. Our
aim is to recreate in its entirety, the original performance by not adding or
subtracting anything, irrespective of the source.
Minimalist User Interface
We carefully study the user interface and par down the number of buttons and
associated clutter leaving just the essential and no more. How tempting it has
been over the years to loose sight of our core values as technology or trends
have made it possible. That is one of the reasons why our older products still
have such a high resale value today. The user interface has and always will
remain simple, free from adornments, clean and uncluttered.
Minimalist Aesthetics
Our products appeal to those who seek the ultimate in audio exclusivity, namely
the perfect blend of “form and function”.
16
“Form and function” are both tough masters. That is why our amplifier heat
sinks are not hidden, but instead feature prominently in all our designs. We
make no excuses for producing some of the most distinctive high-end audio
products on the planet. We let “form and function” blend together in perfect
harmony. This surely is the essence of true minimalist utilisation.
Minimalism in a Wider Context
John Pawson writes:
“Clearly simplicity has dimensions to it that go beyond the purely
aesthetic: it can be seen as the reflection of some innate, inner
quality, or the pursuit of philosophical or literary insight into the
nature of harmony, reason, and truth”.

Special Design Features
Rugged Build Mechanical strength has been a hallmark of Perreaux products since the
Quality company first started production back in 1974. The concept behind the physical
design and construction is that each structural member should contribute to both
rigidity and performance.
Multiple There is a separate regulated power supply for each section of the CD player.
Regulated One positive supply and one negative supply for the sensitive analog output
Power stage, another one for the DAC section, another for the clock generation of the
Supplies DAC section and a further supply for the microcontroller and display. The
advantage of this is that there is complete isolation from stage to stage, ensuring
the analog section is completely free from digital noise.
Burr Brown The CD1’s precision transport is backed up by a Burr Brown (Texas
DAC Instruments) digital to analog converter. Multi-level Delta-Sigma operation with
8x over-sampling ensures the CD1 will deliver a high level of audio
performance.
Balanced The CD1 offers a balanced analog output, providing improved noise rejection
Analog and cancellation.

Maximising System Potential
Interconnects An often-ignored area in high fidelity systems is the cabling connecting the
and Speaker various components. Interconnect leads should be high quality cable with
Cables substantial terminations. Gold plate is inherently resistant to corrosion, and an
excellent conductor. The presence of corrosion induces distortion and poor
conductivity will seriously interfere with sound quality. Terminations must plug
snugly into sockets to maintain maximum conductivity and to avoid annoying
earthing problems.
Speaker cabling is equally critical. Use only solidly constructed cable of high
purity copper or silver content.
Again, gold plated terminations are
recommended, of the spade or banana plug type. Use cables of equal length and
as short as possible to maintain uniform electrical resistance at the lowest
possible level. If your amplifier is closer to one of your speakers than the other,
avoid coiling the longer lead as this can create inductance, with the potential of
reduced high frequency performance. Keep all connections clean, firm and
tight. The traditional adage that a chain is only as strong as its weakest link
most certainly applies to audio systems.
Balanced The use of the balanced signal outputs can have the effect of cleaning up hums,
Interconnects buzzes, radio frequency interference (RFI) and general extraneous rubbish that
can enter an audio system. A balanced signal input system operates on the
principle of differential amplification. The positive and negative inputs are
contrasted against one another and the difference between them is amplified.
Noise entering the system is imposed equally on the positive and negative
signals and therefore will not be amplified, as no differential voltage exists.
The term used to describe the quality of the effect is called Common Mode
Rejection Ratio (CMRR). CMRR is an equipment and system specification,
which describes how well unwanted common mode signals are counteracted
when used in conjunction with balanced connections. CMRR action prevents
the egress and build up of extraneous hum; buzzes and RFI when analogue
signals are conveyed down cables and between equipment powered from
different locations and is widely used in professional audio applications.
Positioning Positioning of your source equipment (tuner, video, disc, tape, record, decks) is
Ancillary important. To avoid airborne frequency peaks, place them well away from your
Equipment loudspeakers and not in the corners of your listening area.
Final High fidelity systems are an investment deserving of careful thought and
Thoughts personal time. Your preferences, priorities and constraints will dictate the
parameters of your purchase, your ears will tell you what is the right choice for
you. Our experience tells us that the bitterness of dissatisfaction lingers long
after the fragrance of cheap price is forgotten, hence our use of the term –
investment.

Care and Maintenance
The CD1 has been designed to provide many years of trouble free enjoyment.
Note:
Please switch the unit off and remove the cord-set from the rear of the
amplifier before attempting to clean your CD1 in the manner described
below.
Never apply liquid directly to the CD1.
Never use abrasives.
Never rub in a circuilar motion.
Cover The cover features a durable, high quality powder-coat finish. To remove finger
marks and dirt, lightly rub the surface with a soft cloth.
If the dirt is not removed, dip your cloth in a mild solution of soap and water,
squeeze excess moisture from it and then gently reapply to the surface.
Stubborn dirt may be removed by the application of a small quantity of
methylated spirits, applied directly to the cleaning cloth only and reworking the
effected area.
Front Panel The CD1 front panel features a high quality electroplate finish. Over time the
surface may retain finger marks and may need to be cleaned to restore it to
original condition.
Regular Cleaning
Gently wipe the front panel with a very clean cotton cloth. Wipe across the
surface and never in a circular motion.
Removing Stubborn Marks
Only attempt this infrequently, as too regular or vigorous application may
damage the surface.
Apply a small quantity of any car polish containing carnauba wax to a very clean
cotton cloth.
Note:
The car polish must state “Safe for Clear Coats” as the polish will therefore
contain the absolute minimum amount of abrasive compound.
Gently wipe over the front panel in lateral motion, allow to dry and then gently
wipe off with a very clean cotton cloth.

Faultfinding Your System
Cause and Hum is a particularly annoying form of noise in any high fidelity system and at
Elimination some time has been experienced by many of us.
of Hum
Hum may result from a number of different situations and to make matters
worse maybe caused by a seemingly illogical combination of circumstances.
One or more of three specific causes creates hum in the system.
Induced Hum
Hum can be induced into the system from one or more sources and is generally
associated with the radiation of noise from one system into another.
Hum and noise can be radiated from any object or system involving AC voltage
and current such as power supplies in amplifiers, motors, switching equipment
etc. All of these may be found in your hi-fi system or within your own home.
Hum may be induced into any part of the system, so there are no specific
instructions that can be given which will offer a guaranteed cure. A good
practice to adopt is to keep low-level signal equipment such as phono systems,
tuners etc. well away from high-level signal equipment such as power
amplifiers. Alternatively, careful designs must be employed to negate these
effects on low-level signal equipment. Another good practice to adopt is to keep
all signal leads away from power leads.
The practice of neatly tying excess leads together for a tidy looking installation
should be resisted, as this could be the cause of induced hum in the system.
Earth Loops
Earth loops are a particularly annoying cause of hum in the system. Earth loops
are created by mains frequency current flowing in the screen of signal leads and
becomes apparent with the lack of adequate earthing between the various pieces
of equipment making up the hi-fi system. This is further compounded by the
fact that the equipment earthing considerations vary between different
manufacturers and countries.
Perreaux products used with equipment manufactured by other manufacturers
may cause an earth loop situation, but Perreaux products used with other
Perreaux products will not cause an earth loop situation provided the following
precautions are observed:
ꢀ
The entire hi-fi system must be connected to the same mains/line power
outlet. This will ensure that each piece of the system shares the same earth
or ground. This rule applies to all installations of all brands of equipment.
A preamplifier or power amplifier may be operated from an extension cord
plugged into the same mains/line outlet.

ꢀ
ꢀ
ꢀ
When a piece of equipment is supplied with a threepin mains/line supply
lead all three pins must be connected in the correct fashion - see your
dealer if in doubt.
Check all interconnecting signal leads for good connections, both internal
connections and firm contact with the sockets. While the centre pin may
make firm contact, it is very important that the outer contact is also firm.
Never remove the earth/ground wire from the mains/line supply of any
piece of equipment. This could be hazardous.
Broken Earth Connections
This is a common cause of hum and noise in the system. In many instances, the
only way to eliminate the possibility of hum problems arising through a broken
earth connection somewhere in the system is to physically check every
connection.
Identifying When experiencing a problem, such as one channel not working, or a noise in
and Isolating one channel, it is good practice to adopt a method of isolating the problem to a
Problems specific item or area. This practice will assist in diagnosing, curing, or at least
advising your technician of the problem and result in a saving of time, money
and perhaps frustration.
A logical approach to isolating the probable cause of the problem is to start at
the loudspeakers and work back to the music source, eliminating each piece of
equipment in turn.
Caution!
Observe precautions regarding volume control settings. Please make all
changes at minimum volume setting. Only increase the volume after the
connections have been made.
Check that the entire system is connected in the proper manner and that the
mains/line supply is connected and switched on.
For clarity during this section, we have labeled one loudspeaker ‘A’ and the
other loudspeaker ‘B’. In this example, loudspeaker ‘A’ appears faulty.

Step 1 – Loudspeakers
SOURCE
AMPLIFIER
A
B
Change the loudspeaker leads from one loudspeaker to the other. If the fault
remains in loudspeaker ‘A’, then loudspeaker ‘A’ is at fault, go no further.
If the fault now appears in loudspeaker ‘B’ then the problem lies further up the
line. Move on to step 2.
Step 2 – Loudspeaker Leads
SOURCE
AMPLIFIER
A
B
Change the loudspeaker leads completely from left channel to right and from
right channel to left by now swapping them at the amplifier output. If the fault
now appears in loudspeaker ‘B’, then that loudspeaker lead is at fault, go no
further.
If the fault appears in loudspeaker ‘A’ then loudspeaker leads are OK. Move on
to step 3.
Caution!
Restore the loudspeaker leads to their original connections at both ends.
Step 3a – Inputs (Channels)
SOURCE
AMPLIFIER
A
B
Change the input plugs on the rear of your amplifier, as follows: Change each
input source in turn by swapping the plugs left to right and right to left. If the
fault changes to loudspeaker ‘B’ on any one of the selected inputs, then that
particular input source is possibly at fault. Move on to step 3b.
25
If the fault stays in loudspeaker ‘A’, then it is probable that the fault may exist
within the amplifier.
Caution!
Changing of any connectors must be carried out at a minimum volume
setting. Only increase the volume after the connections have been
changed.
Step 3b – Inputs (Interconnects)
SOURCE
AMPLIFIER
A
B
Change the interconnect leads completely from left channel to right and from
right channel to left by now swapping them at the source component’s output. If
the fault stays in loudspeaker ‘B’, then the interconnect lead is at fault, go no
further.
If the fault appears in loudspeaker ‘A’, then the interconnect lead is OK.
Caution!
Changing of any connectors must be carried out at a minimum volume
setting. Only increase the volume after the connections have been
changed.
Should the fault prove to be in the amplifier it will be necessary to determine
where the fault actually lies. Most of this has been done, for instance, you now
know what input/s and what channel is affected. This information will assist
your Perreaux dealer or service person when or if any service is required.
If the apparent fault is noise in one or both channels and has been localised to
the amplifier, it will be necessary to determine whether or not the noise increases
with the volume control; whether or not the noise exists when no input at all is
connected to the amplifier; and what type of sound the noise is. For example,
low frequency humming noise or high frequency hissing noise.
This
information will also assist your service person in making repairs or
adjustments.

Specifications
The CD1 specifications are detailed in brief and then subsequently in more
detail. In the detailed version, we attempt to explain the significance of each
specification.
The correlation between published specifications and sonic quality can be
unreliable. A list of numbers reveals virtually nothing. All technical
measurements must be subject to qualitative as well as quantitative
interpretation. Measurements of the CD1 reveal excellent results by any
standards. Tested at 115V and 230V after a 10 minute warm up period.

Explained
This is the reference output level to which other specifications, such as signal to
noise ratio and total harmonic distortion, are referred.
Digital Output............................................................................................0.5Vp-p
Indicates the peak-to-peak voltage of the signal from the digital output.
Output Impedance ..................................................................................... 100Ω
Output Impedance indicates the ability of the unit to drive the Line Level
Output. The low impedance of the CD1 means that it will drive any
combination of cable configuration (length, capacitance, etc.) and component
impedance with ease whilst maintaining signal integrity.
Digital Load Impedance................................................................................75Ω
Specifies the load impedance required for the coaxial digital interconnect.
Frequency Response ................................................... 20Hz to 20kHz, ±0.5dB
Describes the frequency range where the amplitude or strength of the output
signal deviates from the source material by no more than 0.5dB
Total Harmonic Distortion (THD+N).......................................... 0.004% @ 1kHz
Total Harmonic Distortion + Noise is the percentage of output signal which is
made up of frequencies added due to harmonics of the fundamental frequency
and noise.
29
Intermodulation Distortion...................................................... 0.004% @ 1kHz
A complex form of distortion occurring when two signals at different
frequencies are produced at the same time, creating additional signals at various
other frequencies and at various amplitudes.
Signal to Noise Ratio............................................................................... >105dB
The ratio of desired signal to noise signals present in the output. This figure is
referenced to the rated output of the CD player, taking into full account all
potentially annoying hum components.
Dynamic Range....................................................................................... >100dB
The difference between the loudest and quietest portions of a signal. Due to the
increased dynamic range offered by HDCD encoding, this specification must be
greater than the 96dB limit inherent in the standard 16-bit CD format.
Channel Separation..................................................................>110dB @ 1kHz
Refers to the immunity of a signal from one channel leaking to the other
channel. The higher the value, the better the isolation of the two channels.
Channel Balance...................................................................................... ±0.5dB
The maximum difference in the output level of one channel compared to the
output level of the other channel.
Phase Linearity .............................................................................................±0.5°
This shows the difference in phase of the input to the D/A converter compared
with the analog output.
