Dear clearaudio customer,
Congratulations on the purchase of your new
Double Matrix Professional record cleaning machine, an
extraordinary product made by clearaudio.
The cleaning of dirty or used records improves the overall sound quality. This also applies to new vinyl
records as there is often residue left over from the pressing process.
Please read this user manual with great care, to avoid misuse or void of warranty.
Why
Double Matrix Professional ?
Many analog and music lovers, as well commercial and professional organisations asked us how it is
possible to clean vinyl records both thoroughly and quickly, and if placing the just-cleaned side of the
record on the potentially dirty turntable platter can be avoided during the process.
It is obvious when cleaning large numbers of records, especially under commercial circumstances, that
time is money.
To achieve this goal clearaudio set about designing a semi-automatic record cleaning machine that
would perfectly clean both LPs and EPs, eliminate any electrostatic charge, without the need to flip the
record over and complete this process within one minute. This required a revolutionary and
outstanding product to be developed. An intensive research and development program led clearaudio
to achieve not only these criteria but also the additional goals of efficiency, easy-of-use and longevity.
The result is the clearaudio
Double Matrix Professional.
Materials and craftsmanship
The clearaudio
Double Matrix Professional is massively constructed from the highest grade of
materials and components. The rigid housing is machined from 4.5 mm thick aluminum plates and the
platter is made out of 10 mm thick aluminum. The corner poles, feet and the fluid tank are made out
of very rigid materials. This contributes towards the substantial total weight of approximately 16.5 kg.
The following pages will explain how to operate your clearaudio record cleaning machine correctly.
We wish you years of satisfaction from your new clearaudio
Double Matrix Professional.

2. Features - overview
Both sides cleaned simultaneously
Due to the sophisticated design of the wash and vacuum arms it is now possible to clean both sides of your
precious vinyl at once.
A sophisticated magnetic mechanism is used to ensure constant brush pressure resulting in more consistent
performance as well as improved speed of use.
Left-right turn switch
The best cleaning results are obtained by cleaning in both directions.
Continuously variable speed regulation
By providing variable speed rotation the dirtiest records can be cleaned at a slower speed preserving both the
microfiber strips and your record.
Cleaning of LPs, EPs and Singles
The
Double Matrix Professional is able to clean all these formats without any additional accessories.
You even do not need to change the cleaning vacuum arms for the different formats.
Excellent cleaning
The
Double Matrix Professional cleaning process raises the audible improvements to a new level that regular
cleaning machines do not reach. This is proven by our laboratory measurements.
No platter
The vinyl records are not placed on any potentially dirty surface such as a turntable platter but are supported on
a label-sized platform. The integrated cleaning and vacuum brushes stabilize the vinyl disc during the cleaning
process and the record labels are completely protected both above and below by two of the highly regarded
clearaudio Seal Clamps.
Cleaning in half of the time
Both sides of any record are cleaned simultaneously reducing cleaning time by at least 50%. Especially in
commercial use, this is an unbeatable advantage.
Integrated filter
To avoid contamination by dust or other particles the Double Matrix Professional has an integrated micro filter
ensuring a long life for the cleaning brushes and your vinyl.
Ease of use
The cleaning process and maintenance procedures are particularly easy and user-friendly.
Perfect cleaning fluid control
Unlike many other machines on the market only the fluid that is required will be dispensed. This is achieved by
two electronically controlled magnetic valves which also ensure that no fluid is able to transfer while vacuuming.
Antistatic brush
The high efficiency antistatic brush completely discharges static and may be used separately from the cleaning
process.
Noise reduction
The
Double Matrix Professional is acoustically damped for low noise levels during use.

3. Set up
Place the
Double Matrix Professional on a stable surface such as a table or rack. Please note that due
to the weight of the
Double Matrix Professional it could damage soft surfaces, or through movement of
the
Double Matrix Professional the surface could suffer scratches. Please make sure that the surface is
able to withstand temperatures of up to 60°C.
3.1 Connecting the mains power
Connect the supplied power cord first to the IEC connector at the rear panel of the
Double Matrix
Professional
then connect it to the power outlet. Please make sure that the appropriate
connector is used and that the voltage is correct. Please refer to the type sticker next to the IEC
connection.
The best results will be achieved when the
Double Matrix Professional is used in a room temperature of
between 15°C and 30°C.
3.2 Switch On
Next to the IEC connector is the mains power switch (pic. 4). When the unit is switched on the red
light of the switch is illuminated.
Make sure that the appropriate connector is used and that the voltage is correct!
Now your
Double Matrix Professional is ready to be used.
Before use please finish reading the complete user manual!

Antistatic brush
The antistatic brush (Pic. 6) is used to discharge any electrical charge that may be present or that is
generated while cleaning. After vacuuming make sure that the record surface is completely dry then
place the antistatic brush in position by rotating it clockwise (towards the record). Leave it in place for
at least one complete revolution.
This Function can be used to remove static even if you did not clean the record.
If the carbonfiber brush hairs do not make good contact with the record surface use a comb to put the
carbon hairs back in position.

Upper and lower cleaning arms
The upper and the lower cleaning arms perform the functions of applying the cleaning fluid, cleaning
and vacuum drying. When the upper cleaning arm is in its working position (pic. 9) there is a constant
pressure on the record. In the rest position (pic. 8) the upper and the lower cleaning arms are
automatically retracted from the record. The upper cleaning arm (pic. 10) can be rotated 90°. The
lower cleaning arm cannot be moved. The magnetic mechanism automatically raises the lower arm to
the operating position when the upper arm is swung into operating position above it.
On each side of the lower cleaning arm (pic. 10) are the fluid drains. These provide built-in protection
against spillage if too much fluid is used while cleaning. Excess fluid will automatically run through the
blue tube back into the reservoir.

Cover filler hole
Using the supplied funnel carefully fill the fluid reservoir with clearaudio Pure Groove record cleaning
fluid.

Outlet tube & plug
By pulling out the plug you can empty the used cleaning fluid out of the fluid tank
(see page 14).

clearaudio Seal record clamp
The clearaudio Seal record clamp (pic.11) has been developed to cover and protect the record label
and to hold the records securely.
On the outer aluminum ring are two small vacuum release holes. This makes it easier to release the
clamp after the cleaning process.
Important!
Please place the Seal record clamp with some pressure on the record in order to avoid unwanted
record slipping!
