Tin plating
SUPRA
®
Classic
A Supra concept for
cleaner sound.
The tin is of higher
resistance than copper
and also protects copper
from bad sounding
corrosion. It also minimises the current jumps
from wire to wire over
corroded copper surfaces while more of the
signal passes through
the pure copper inside
the wires. The tin layer
also minimises the skineffect, by acting as a
semi-Litz.
Silver plating
Prior to 1976 loudspeaker
cables had no identity. They
were simply cables.
2 x 0.5 mm² was the most
usual size, while for high
specifications, the only
alternative was 2 x 0.75 mm².
And then there was SUPRA.
It began when we introduced
SUPRA 2.5 and shook up
the entire market with a
whole new concept. All this
happened in Sweden 1976.
Since then the whole world
has followed us. But then
the adjustable spanner, the
propeller, the safety pin and
Dynamite have also come
from Sweden, so perhaps it
is not so surprising.
Since SUPRA 2.5 was introduced, other original ideas
have come from SUPRA.
The nylon screen, the Swift
connector, the stretch-proof
multicore cable and the Ply
conductor concept are all
examples of our forward
thinking technology.
Only when the frequencies are very high, as in
digital signals, does it
seem wise to go the
opposite way, i.e. to
silver plate for a lower
surface resistance. At
such high frequencies it
is hard to keep the
signal inside the wire, so
instead we design for an
easier surface current
flow.
Digital interlinks
Important properties of
digital cables are a high
propagation velocity
factor and a correct and
stable characteristic
impedance (Z).
Analogue
interconnects
Low capacitance (C) is
important.
Microphone- and line
cables
Low microphonic effect,
and low capacitance
assist quality.
Loudspeaker cables
Loudspeaker cables
generally need to be of
low inductance (L) and
preferably also of low
resistance (R).

Classic Loudspeaker Cables
Hi-Fi
The Classic series comprises highly flexible
cables of tin plated multistranded OFC
copper of purity degree 5N, which means
>99.999% pure, i.e. purer than five nines.
The insulation of special ion stable PVC
minimises corrosion of the sonically benign
tin surface.
This series covers all Hi-Fi applications
from low power speakers, such as rear
speakers of home theatre systems, to high
power systems with long cable lengths.
How to connect Rondo 4x2.5 for lowest inductance
Connecting Rondo as shown in the figure below will
make a lower inductance of 0.22 mH/m, which in turn
makes Rondo a top class high-end loudspeaker cable.

Supra Ply, a Logical and Scientific Design
Before considering more special ’esoteric’
2nd and 3rd-order effects, such as
conductor metallurgy, the performance of
audio cables is principally determined by their
series loop resistance (R), their series loop
inductance (L) and their shunt capacitance
(C). Both the absolute and the relative values
of R, L & C matter. For speaker cables
connecting high performance amplifiers to
every day electrodynamic (moving coil or
ribbon) speaker drive-units that are desired
to operate with fidelity across the audio
band, the R & L (cable resistance &
inductance) must both be low, while the
value of C (capacitance) does not matter
much [1,2]. This is so because current flow
into conventional speaker drive-units is
relatively so much larger than in line-level
connections, and also absolutely large,
ranging to over 100 Amperes in some
instances. This is especially true of auto (12
volt) installations. But simply using a fat wire
gauge makes R low at the expense of
increasing L. This is musically unacceptable
for high sonic quality.
’Squaring the circle’ techniques to make this
loop inductance, L, low, simultaneous with
low resistance, include tapes, either stacked
in parallel pairs, or several arranged side-byside in ribbons, where the ends are Xconnected. But of course, these types are (i)
impractical to fit to nearly every known
speaker connector (at least without
introducing discontinuities), (ii) are stressed
and may be unsightly when right angle
surface bends are required in domestic
installation, and (iii) are unsuited to for
mobile use by professionals. Litz
techniques, i.e. multiple, parallel, insulated
conductors are more practical in use and
laying out, but when properly executed,
they are expensive.
They are also awkward to terminate and
must be soldered. Other types are grossly
large, like industrial pneumatic pipes, making
them unsuited to smaller domestic
dwellings.
Conventionally, fat conductors’ high loop
inductance (which raises impedance at
+6dB/octave) is further raised due to
internal eddy currents causing ’Skin effect’.
This acts like ’the square root of an
inductor’, i.e. progressively adds a +3dB/
octave component to the cable’s series
inductance. With typical speaker cable runs
of a few metres, the combined inductive
effect is that performance in moderately
heavy, plain conductors is measurably
affected with steady signals at or a little
above 1kHz. Whereas for music transients,
even low bass qualities are affected.
Conventional stranded cables with copper,
silver or related conductors suffer from
complex oxidation. The surface becomes a
semiconductor. The diodes so formed
between the strands are not seen by
steady-state signals, but look like the plates
of a high value capacitor to transient
4
signals. This causes low-level energy
storage and release after transients, that is
invisible to steady state testing yet nonetheless perfectly audible with many music
recordings. This ’transversal distortion’ may
also be described in terms of the TEM
(Transverse Electro-Magnetic) Wave,
which takes a direct route, whereas
electron flow is ’trapped’ inside individual,
particular strands that are commonly
twisted away from the most direct route, at
each of the inevitable bends in a stranded
cable, when laid-out.
Supra Ply is able to be a large-section, low
resistance cable, while also overcoming
skin effect and transversal distortion, by
using a proprietary, pure tin plating. This
has the double benefit that tin and copper
meld without forming a diodic barrier (as
with many silver-plated copper ’audiograde’
conductors) and that tin strongly resists
most common causes of metal corrosion,
and hermetically protects the copper,
making Supra Ply ideal for outdoor use.
By contrast, most audiograde cables
claiming highly pure copper or silver
conductors are either wholly unprotected
from contamination, initially by the outgassing of the plastic covering (even if
PTFE/Teflon), and eventually from the
impure atmosphere - and even from
accidental immersion in liquids! Some very
expensive cables are protected only by a
very thin, initially good lacquer, that must

shows progressively increasing losses
above 1kHz for all cables, caused by
inductance + skin effect - ranging up to
10dB at 20kHz or so, where ultrasonic
sound from vinyl discs in particular, can
simulate pleasure centres in the brain [3].
Here, Supra Ply’s healthy, low-loss
behaviour at the higher audio frequencies
(and, by implication, the transient parts of
lower frequency music fundamentals) is
made evident with a basic ’steady-state’
sine-wave sweep.
Even if oxidation should form on the outside
of Supra Ply, it will be sonically benign, as in
audiograde ’metal oxide’ resistors - which
are really tin oxide.
Other Advantages
For wiring-up, Supra Ply is easily formed.
Unlike ribbons, tapes and Litzes, the
rectangular conductor section is instantly
made circular, for insertion into the circularshaped receptacles of binding posts, 4mm
(’banana’), Speakon, XLR and most other
speaker connectors.
Supra Ply’s overall square X-section allows
it to readily enter most connector housings,
too.
Supra Ply is also readily coiled up, like
ordinary, inferior-sounding ’mains power
type’ speaker cables. It is therefore easy
for professionals to use. Sound producers
can easily take Supra Ply to the mixing
venue along with their favourite minimonitor speakers.
Demonstrating the Difference
Fig.2 & 3 are ’scope pictures, in the steadystate time domain. They show typical
damping (dynamic) differences, using a
classic square wave. After a transient
event, Supra Ply both restrains the peaking
and accelerates the return of the signal
voltage to zero volts, at the speaker end of
the line. The peaking of the wide-spaced
cable demonstrates both bad damping, and
hf loss. These effects occur because
spaced cable has high inductance and low
capacitance - the diametric opposite of
what is required to drive ordinary
loudspeakers.
Unlike some audiograde products, the
benefits of Supra Ply (and other cables
employing similarly logically progressive
philosophies) are readily shown by
comparative and repeatable measurements.
These differences may be portrayed in a
number of realms.

The shielding is also highly effective in
rejecting high frequency interference, by
minimising aerial pick-up.

Accessories for bi-wiring
Bi-wiring is a separation of the music signal current into
two cables; one for the higher and one for the lower
frequency range, e.g. one for bass and one for the
midrange/tweeter.
Bi-wiring makes an audible enhancement. The best
combination is a pair of Ply 3.4 or 3.4/S.
In order to make it work the loudspeakers should
preferably be equipped with separate inputs to the crossover networks. If not, then you could move out the crossover network from the loudspeaker boxes and put it close
to the amplifier. It should then be easy to make a bi-wired
connection from the crossover to the loudspeaker
components.
Nylon braid ’hose’ is available for sleeving over the cables
to gather them into a single bi-wire cable pair.

You do it like this:
The braid sleeve widens when it is pushed together
longitudinally, which makes it very easy to push the cable
pair into it. The braid sleeve is supposed to be somewhat
shorter than the cable pair to leave a margin to be stretched
afterwards in order to tighten against the cable pair.
A heat shrink at each end fixes the stretched braid sleeve
and completes the work.
Please be aware: A very tense stretching makes a neat
result, but also a less flexible cable.

EFF-I Interconnect Cable
Analogue/Digital 75 Ohm
The dynamic influence of the skin effect is of great sonic
influence as the music/video signals are nothing but
variations. By means of the Equalized Frequency Flow
technique (EFF) Supra takes skin effect into account. The
EFF-I cable consists of two tube-shaped conductors with a
wall thickness of 0.20 mm which is well below the smallest
skin depth within the audio range. This makes all
frequencies operate under the same conditions.

DAC Digital & Analogue
Interconnect Cable, AES/EBU
Harmonised
A fast interconnect of extremely low capacitance. In accordance with our design concepts the inductance is to be low
for a loudspaker cable whereas for an interconnect the
capacitance is to be low. Supra DAC is insulated with PE
foam skin which exhibits only 45 pF/m. It is screened with
our very efficient and strong semiconductive nylon ribbon.
Supra DAC is also designed for digital audio and is
harmonised with the AES/EBU standard. (Square wave 60
MHz, impedance 110 Ohms, balanced.)
The very high frequency properties of Supra DAC are
outstandingly good, owing to its high velocity factor. More
clean transients and thus improved space dimension
comes with the high velocity.
The velocity factor of Supra DAC is as high as 78% of the
speed of light, owing to the low dielectricity of the gas blown
foam skin insulation. With PTFE/Teflon it would have been
only 71%.
DAC Digital & Analogue Interconnect
Application examples: Digital audio with XLR-interface 110

The velocity factor can be calculated with the simplified
n = Ö1/K
formula:
where K is the dielectricity factor of the insulation material.

Trico Co-ax/75 Ohm Digital Video
Composite Cable 75 Ohms
Trico is an interconnect cable of very low capacitance, insulated
with PE foam which produces only 58 pF/m and makes the
propagation velocity 78% of the speed of light.
Trico is double shielded with a braided inner screen of silver
plated oxygen free copper and an outer of bare OFC-braid. The
screens provide efficient noise protection. The centre
conductors are made of silver plated OFC copper. The silver
plating of the conductor/screen enhances the high frequency
properties of the cable.

AV Series Audio/Video Multi Core
Co-ax 75 Ohms
The AV cables are multi-core coaxes of individual 75 Ohm
rated coax cores.
Each core has a braided screen of tin plated OFC.
The AV series is of very low capacitance owing to the PE
foam insulation.
The construction is especially developed for Home Theatre
use and allows several applications with DB25, Scart, RCA,
S-VHS and BNC connectors.
The timing error is less than 2.2 ns which enables
accurate RGB transmission.
Applications:
• Component analogue video
• Video walls
• High resolution video projection
• CG workstations
• Studio tie lines
AV-2 Audio/Video Cable 2-pairs
Application examples: S-video. Suitable connector is Supra
S-VHS 7 and/or Supra Scart plugs.

AV-6 Interlink for AC-3/DTS Surround
AV-6 is a high performance multi-coax construction of low
capacitance 75 Ohm cores, especially developed for 5.1
channel home theatre sound (Dolby digital/DTS). All
connectors are fully shielded.
The cores are used for:
• Right front
• Left front
• Center
• Sub woofer
• Right surround
• Left surround
All cores are marked for easy installation.
The DB25 is a rather new connector in Hi-Fi and is rapidly
becoming more common. For ex. Rotel, Arcam and Onkyo
are using it as a standard in some of their home theatre
products.

ZAC Fibre Optic Interconnect
ZAC stands for Zero Attenuation Concept.
The innovative curving of the fibre core tip to get a zero
divergence loss enables plastic fibre optic to be used, and
achieve the same transmission quality as that of a glass
fibre core. Thus, we combine the strength and flexibility of
the plastic fibre with a high-end Hi-Fi transmission.
Properties and advantages of the fibre optic cable are:
• Low weight • Wide band width • Interference immune
• No radiation • Independent of voltage potentials.
ZAC Toslink
Our most popular Toslink. ZAC Toslink is available in 1m (3ft),
2m (6ft), 4m (13ft), 8m (26ft).
ZAC Mini
The same concept but fitted with Mini Toslink connectors.
Available in 1m (3ft).
ZAC MinTos
The same concept but fitted with Mini-Toslink at one end and
a Toslink at the other. Often used between Mini discs and CD
players. Length: 1m (3ft).
X-ZAC and ZAC Fiber Optic Cables

Alta Fidelidad
An exact fit is also important in order to avoid divergence
losses. Therefore X-ZAC is provided with a high precision
metal connector for exact fit. The fibre optic is principally the
same but the X-ZAC is machine polished in further three
stages. Available in 1m (3ft).

Digital Interconnects
General:
Always, in digital applications, the use of a cable with the
correct characteristic impedance is very important. There
are two standard impedances:
• 75 Ohm S/PDIF interface which uses RCA connectors.
This is most common in Hi-Fi applications from CD
transport to DAC, as well as home recording.
• 110 Ohm AES/EBU interface which is balanced and
has XLR connectors. This is mostly used in
professional applications.
75 Ohm Interconnects: Trico-RCA, Trico-BNC
and EFF-ID
The 75 Ohm digital interconnects are designed for RCA
(Phono connectors) interfaced transmission between CD
transport and digital to analogue converter. They have the
capability to transfer the full digital spectrum and can be
used with a number of 75 Ohm applications.
DAC-XLR Gold Trico-BNC Trico-RCA
110 Ohm AES/EBU Interconnect: DAC-XLR
DAC-XLR is a balanced interconnect for digital transfer,
mostly in professional equipment. DAC stands for Digital &
Analogue Cable, not to be mixed up with DAC converters.

Connection Configurations
For those of you who prefer to make your own
interlinks or carry out service we have
gathered this connection configuration tables.
Please be aware of the importance of the
soldering quality. All Supra interlinks are
soldered with lead-free silver tin and noncorrosive flux. We recommend Multicore 96S.
The galvanic potential of silver is closer to
copper than is led to copper and thus the
galvanic voltage will be minimised.
Poor solderings are mostly due to either too
high or too low a temperature.
Flux is needed to get through the oxide and
avoid a dry joint without overheating.
A dry joint might work very well for a period of
time but as the oxide will grow between the tin
and the object there will eventually be a poor
connection. In the worst case the conductors
will get loose and create a short circuit.
The Supra connectors are insulated with
Teflon to withstand the right soldering
temperature.
However, we always recommend to leave the
soldering of interlinks with a professional
workshop.

Cables for Fixed Installations
The radiation from unshielded loudspeaker cables is often
stronger than that from ordinary mains cable applications.
The minimising of interference fields is recommended in
all fixed installations, with computers playing an
increasing part in everyday life. Sensitive networks of low
level information controls all kinds of operations including
audio, video, production processes and the like.
These systems are getting more compact and more
complex with more cables closer and closer which means
that the sensitivity to disturbances increases
correspondingly.
Multi room installations often require audio, video, data
and loudspeaker lines to run through ceilings and walls in
very close proximity.
Furthermore, biological effects due to electric and
magnetic alternating fields should also be considered.
See connection diagram on page 17.

Microphone and Line Cables

Supra’s unique screen concept makes pro-tech
products that are feasable for military use as well as for
industry or stage use. The screen is made of
semiconductive Nylon, a very strong and flexible
wrapping that so far has only been used around very
high voltage power station cables, for field equalizing.
The advantages of Supra nylon screened cables over
ordinary braided cables are:
• Mechanically stronger
The nylon screen, with its tensile strength of 500 N/50mm,
is many times stronger than ordinary screens, also with
respect to bending fatigue.
• Enviromental and climate immunity
Humidity does not influence the cable’s electrical
properties.
• Noise rejection
Besides the extremely good shielding properties of the
semiconductive screen, the cores are symmetrically
twisted to avoid the magnetic pickup. Tests under very
severe conditions have been carried out and whereas no
ordinary cable has been free from noise pickups, Supra
MBS has still been quiet.
Carry out your own test: Tape a nylon-screened Supra
cable along the mains flex of a thyristor controlled device,
for example, a drilling machine. Connect the Supra cable
to a pre-amplifier, run the machine and listen to the
crosstalk noise. Do the same with other cables. Compare!

Stage Multi Cores
Multicore Cables for Stage Use,
Pair Jacketed and Stretch-Proof
Supra has developed a flexible multi-core cable for use on
stage and in heavy and rough handling situations. Every
pair is individually jacketed and is a complete cable. Just
simply solder on a contact - you don’t even need to use
heat-shrink. Perfect when you need to make up a line to a
stage box. The screen is of semiconductive nylon which is
extremely strong with regard to bend-fatigue and which at
the same time is highly resistant to electro-magnetic
interference. A usual problem with multi-core cables
which are used on stage and in other non-permanent
applications, is that the pairs in the middle of the
multicable have less stretch tolerance than the outer
layers, owing to the spiralized configuration of the cable.
Consequently the inner cables are often stretched so
much that the solder joints give way or the conductors
break when forced to take the whole strain. Supra have
solved this through increasing spiralization of the pairs
towards the centre, plus the omission of a pair at the
exact centre, this being replaced with a flexible plastic
core.

Swift XLR Connectors
Patented by Tommy Jenving. Swift has several advantages over other XLR connectors.
• Totally shielded. No electromagnetic leakage.
• No loseable screws. Only one retained screw.
• Nothing to slip on the cable before soldering.
• Strain relief: The screw serves also as a clamp screw
and since it is placed at a considerable distance from the
apperture there will be no bending forces on the cable at
the clamping point.
