Prior to 1976 loudspeaker cables had no identity.They were simply cables.2 x 0.5 mm 2 was the most usual size, while forhigh specifications the only alternative was 2 x0.75 mm 2 .And then there was SUPRA.It began when we introduced SUPRA 2.5 andshook up the entire market with a whole newconcept. All this happened in Sweden 1976.Since then the whole world has followed after us.But then the adjustable spanner, the propeller, thesafety pin and Dynamite have also come fromSweden, so perhaps it is not so surprising.Since SUPRA 2.5 was introduced, otheroriginal ideas have come from SUPRA. Thenylon screen, the Swift connector, the stretch-proofmulticore cable and the Ply conductor concept,and the Assurance of Cable Directionality are allexamples of our forward thinking technology.2

Unlike ribbons, tapes and Litzes, therectangular conductor section is instantly made circular, for insertion into thecircular-shaped receptacles of binding posts, 4mm (’Banana’), Speakon, XLRand most other speaker connectors.Supra Ply’s overall square X-section allows it to readily enter most connectorhousings, too.Supra Ply is also readily coiled up, like ordinary, inferior-sounding ’mainspower type’ speaker cables. It is therefore easy for professionals to use.Sound producers can easily take Supra Ply to the mixing venue along withtheir favourite mini-monitor speakers.Demonstrating the DifferenceUnlike some audiograde products, the benefits of Supra Ply (and other cablesemploying similarly logically progressive philosophies) are readily shown bycomparative and repeatable measurements. These differences may be portrayedin a number of realms.Fig.1, in the swept frequency domain shows progressively increasing lossesabove 1kHz for all cables, caused by inductance + skin effect - ranging up to10dB at 20kHz or so, where ultrasonic sound from vinyl discs in particular, cansimulate pleasure centres in the brain [3]. Here, Supra Ply’s healthy, low-lossbehaviour at the higher audio frequencies (and, by implication, the transientparts of lower frequency music fundamentals) is made evident with a basic’steady-state’ sine-wave sweep.Fig.2 & 3 are ’scope pictures, in the steady-state time domain. They showtypical damping (dynamic) differences, using a classic square wave. After atransient event, Supra Ply both restrains the peaking and accelerates thereturn of the signal voltage to zero volts, at the speaker end of the line. Thepeaking of the wide-spaced cable demonstrates both bad damping, and hfloss. These effects occur because spaced cable has high inductance and lowcapacitance - the diametric opposite of what is required to drive ordinaryloudspeakers.Wide spacedOtherClassicPly 2.0Fig.1 Steady-state cable lossesFig.2 Oscilloscope graph of losses for Ply 2.0Research ReferencesBen Duncan, Loudspeaker Cables, Case Proven, Proc.

Sensitive networks of low level information control all kinds ofoperations.Meanwhile, multi room installations often require audio, video, dataand loudspeaker lines to run through ceilings and walls in very closeproximity.The biological effects of electric and magnetic fields should also beconsidered.Tips and Tricks:For bi-wiring there are Nylon Braid and Heat Shrink in kit on page 26!Tests and ReviewsSupra Ply 3.4/STNT Audio non-commercial internet magazinewww.tnt-audio.com/accessories/ply34s_e.htmlAlta Fidelidad Spain, #100 ’99Hifi & Musik Sweden, Sept. ’99Stereofonia Spain, #195, ’99Hi-Fi Choice England, #203 ’00 ”Recommended”AMPwww.gmx.czStereoTimes www.stereotimes.comSupra LincAlta Fidelidad Spain, #95 ’98Connection of screened loudspeaker cables:Earth screw to chassisScreenSupra Screened Loudspeaker CableNo screen connectionto the loudspeakerItemMechanical SpecificationsElec.

In accordance with our designconcepts, the inductance is to be low for aloudspaker cable whereas for an interconnectthe capacitance is to be low. Supra DAC isinsulated with PE foam skin which exhibitsonly 45 pF/m. It is screened with our veryefficient and strong semi-conductive nylonribbon. Supra DAC is also designed for digitalaudio and is harmonised with the AES/EBUstandard. (Square wave of 60 MHz, impedance110 Ohms, balanced.)The very high frequency properties of Supra DACare outstandingly good, owing to its high velocityfactor.The velocity factor of Supra DAC is as high as 78%of the speed of light, owing to the lowdielectricity of the gas blown foam skininsulation. With PTFE/Teflon it would have beenonly 71%.The velocity factor can be calculated with thesimplified formula:ν = √1/Kwhere K is the dielectricity factor of the insulationmaterial. (See page 27.)More clean transients and thus improvedspace dimension comes with the high velocity.EFF-I Interconnect CableAnalogue/Digital 75 OhmThe dynamic influence of the skin effect is ofgreat sonic influence as music and also videosignals are nothing but variations. By meansof the Equalized Frequency Flow technique(EFF) Supra takes skin effect into account. TheEFF-I cable consists of two tube-shapedconductors with a wall thickness of 0.20 mmwhich is well below the smallest skin depthwithin the audio range. This makes a widerange in the music (or video) of frequenciespass through under the same conditions.EFF-I Interconnect Cable ConstructionSilver plated OFC copper 0.5 mm 2 /conductor.Tube-shaped flexible conductors with a centercore of PE.

The screen is made of semi-conductiveNylon, a very strong and flexible wrapping that so far has only beenused for field equalizing around very high voltage power stationcables.The advantages of Supra nylon screened cables over ordinarybraided cables are:• Mechanically stronger• The nylon screen, with its tensile strength of 500 N/50 mm, is• many times stronger than ordinary screens, including with respect• to bending fatigue.(Exception note: MB-01 does not need this nylon screen, buthas an Aluminum screen, as this cable is meant for fixedinstallations only.)• Noise rejection• Besides the extremely good shielding properties of the semi-• conductive screen, the cores are symmetrically twisted to cancel• out 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 athyristor controlled device, for example, a drilling machine.Connect the Supra cable to a pre-amplifier’s mic or disc input, runthe machine and listen to the level of induced noise. Now, do thesame with other cables.

Technical InformationFor those who prefer to make their owninterlinks and for carrying out servicing, wehave gathered the following configurationtables. Please be aware of the importance ofthe soldering quality. All Supra interlinks aresoldered with lead-free silver-tin with copperand non-corrosive flux, available asMulticore TSC-96, which we recommend.The galvanic potential of silver is closer tocopper than is led to copper and thus thegalvanic voltage will be minimised.Balanced connection with XLRSignal source > Text reading this way >Semibalanced connection with RCASignal source > Text reading this way >Connection of screened loudspeaker cables:Earth screw to chassispÅêÉÉå ScreenPoor solderings mostly due to either too highor too low a temperature.Flux is needed to get through the oxide andavoid a dry joint, without overheating.A dry joint might work very well for a periodof time but as the oxide grow between thetin and the object there will eventually be apoor connection. In the worst case theconductors will get loose and create a shortcircuit.No screen connection to theloudspeakerH- HSupra ScreenedLoudspeaker CableAmplifierLoudspeakerThe screen is to be connected to the amplifier chassis or any otherground point of the amplifier. No connection at the loudspeaker end.-All Supra connectors are insulated withTeflon to withstand the right solderingtemperatures (300°-400°).Therefore, we always recommend leaving thesoldering of interlinks with a professionalworkshop.XLRPin Function Pin Function1 Ground/Screen 3 Cold2 HotDB-25 (D-sub)Pin Function Pin Function1 Left Front + 14 Left Front -2 Center + 15 Center -3 Right Front + 16 Right Front -4 Sub Woofer + 17 Sub Woofer -5 Left Surround + 18 Left Surround -6 Right Surround + 19 Right Surround -Ground chassis - Ground chassisS-video (Y/C)Pin Funktion Pin Funktion1 Luminance (Y) Ground 3 Luminance (Y)2 Chrominance (C) Ground 4 Chrominance (C)ScartPin Function Pin Function1 Audio Out Right 12 Data 12 Audio In Right 13 Red Ground3 Audio Out Left 14 Data Ground4 Audio Ground 15 Red RGB, C at Y/C5 Blue Ground 16 RGB Status6 Audio In Left 17 Video Ground (CVBS)7 Blue RGB 18 RGB Status Ground8 CVBS Status 19 Video (CVBS) Out, Y at Y/C9 Green Ground 20 Video (CVBS) In, Y at Y/C10 Data 2 21 Ground (Shield)11 Green RGBDirectionality AssuranceAll Supra cables are constructed withattention to consistent and equal ‘direction’in all the conductors. Simplistic electronicstheory says there is no ‘directionality’ inconductors, but assumes conductors areperfectly isomorphic. It also ignores theinherently directional nature of signal andenergy flow. Yet electricity could not be soldwithout ‘energy flow directionality’. [1]In reality, practical conductors are drawnmany times - not cast. This creates highlyelongated crystal structures. This in turncreates a physical (mechanical) directionalfeature or ‘axial polarity’. Annealing and also‘burning-in’ processes can reduce the‘strength’ of the ‘drawing imprint’, but onlyto a degree.All conductors in Supra cables areconsistently arranged to point ‘forwards, inthe direction (left to right) implied by thelegend (text) printed on the cable jacket.Directional consistency is ensured in twoways. First, direction of the conductors to beused in each cable is known from the spooleddirection of the conductors received from thecopper wire factory. That is a reliable methodbecause an efficient manufacturing processis consistent and omits random re-spoolingsteps.Forward Thinking TechnologySecond, the ‘directionality’ of conductors isnow able to be measured, and Supra cablesare the first in the world to benefit from aspectral technique developed by audioconsultant Ben Duncan [2] in conjunctionwith Jenving Technology AB. This employssome special test conditions which betterapproximate audio equipment’s real-worldusage than standard, pure signal sources. Testresults show typical increases in harmonic(noise) levels 0.5dB when cables areconnected so the conductors’ drawndirection opposes the signal flow direction. Inreal use the noise difference, which is somedB below the main signal, could be muchgreater. From this, a reduction in such noise(‘more clarity’) is what’s expected, and it isalso one of the things that is heard inpractice - when optimum conductororientation is discovered.Experiences of DirectionalityIn ‘high-end’ audio, ‘Directionality’ means: ‘acable used for audio signal transmissionoffering better sound quality (in variousways) when connected a particular wayround.’ To those sensitive to the sonicchanges, this is repeatable, over spans oftime, or in different systems. In other cases,if the less good direction were chosen, it toomay approach the preferred direction afterburn-in, i.e. a period of use, simple ageing, oreven cryogenic treatment. Such ‘burn-in’processes involve annealing of the metal.Some pundits say that ‘directionality’ (incables) can be heard even on the low quality‘curvy plastic’ low/mid-fi audio equipmentsold in high-street shops. On an highervector, a US high-end enthusiast/ researcher,Doug Blackburn, suggests it is possible thatwhen audiophiles say they hear sonicchanges after changing polarity (byswapping conductors at one point - not byswapping ends as with conventionaldirectionality*) that they’ve actually hearddirectionality instead. That’s because purelydigital (‘software’) polarity reversals mysteriouslydon’t have the sonic attributesassociated with analogue signal polarityreversal.*Here, directionality effect being heard is inthe connected parts (eg. long inductor wires),rather than in the preceding connectiveconductors.Information[1] For background, refer to extensiveinsights in ‘Black Box’ column, by BenDuncan, originally in Hi-Fi News& RecordReview, reprinted 73 part compendium 1994-2000 available from: (http//)www.hifiaccessoriesclub.com - orwww.proaudioaccessories.com.[2] Ben Duncan Research: www.BDR-UK.dial.pipex.com.23

Cable AccessoriesAccessories for bi-wiringBi-wiring is a separation of the music signal current between poweramplifer and loudspeaker drive-units into two cables; one for thehigher and one for the lower frequency range, e.g. one for bass andone for the midrange/tweeter.Bi-wiring makes an audible enhancement. The best combination is apair of Ply 3.4 or 3.4/S.In order to make it work, the loudspeakers should preferably beequipped with separate inputs to the crossover networks. If not, thenyou could move out the crossover network from the loudspeaker boxesand put it close to the amplifier. It should then be easy to make a biwiredconnection from the crossover to the loudspeaker components.Nylon braid ’hose’ is available for sleeving over the cables to gatherthem into a more convenient 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 NylonBraid sleeve is supposed to be somewhat shorter than the cable pair,to leave a margin to be stretched afterwards in order to tightenagainst the cable pair.A Heat Shrink sleeve at each end fixes the stretched braid sleeve, andcompletes the work.Please be aware: A very tense stretching creates a neat result, but alsoa less flexible cable.ABCDEFGH I J KThe final resultNylon Braid KitsThe Nylon Braids are available in Kits withsuitable Heat Shrink sleeving.See the table below.26ItemMechanical SpecificationsPict.

About...Additional Infomation and FormulasSupra ColoursIce BlueAnthracite GreyUseful to know about...Tin platingA SUPRA concept for cleaner sound.The tin is of higher resistance than copper and also protectscopper from bad sounding corrosion. It also minimises thecurrent jumps from wire to wire over corroded copper surfaceswhile more of the signal passes through the pure copper insidethe wires. The tin layer also minimises the skin-effect, by actingas a semi-Litz.Silver platingOnly when the frequencies are very high, as in digital signals,does it seem wise to go the opposite way, i.e. to silver plate fora lower surface resistance. At such high frequencies it is hardto keep the signal inside the wire, so instead we design for aneasier surface current flow.Digital interlinksImportant properties of digital cables are a high propagationvelocity factor and a correct and stable characteristicimpedance (Z).Analogue interconnectsLow capacitance (C) is important.Microphone and line cablesLow microphonic effect and low capacitance assist quality.Loudspeaker cablesLoudspeaker cables generally need to be of low inductance (L)and preferably also of low resistance (R). Impedance is ofgreater importance than simplistic theory suggests becausemusic comprises continuous transients.Directionality AssuranceAll Supra Cables are constructed with attention todirectionality in the conductors. Supra is the first in the worldto prove directionality in conductors by measurements.These measurements are carried out by Ben Duncan Researchon behalf of Jenving Technology.
