Where do you produce your cable and the components?
All Tchernov Cable products (except HDMI and USB cables) are manufactured in highly reputable Russian factories specialized for aviation and space complex. The Cable Series Standard, Original, Special and Classic are produced in the "Chuvashcable" factory in Cheboksary. The Cables Series Ultimate, Reference and Classic XS SC are produced in a design engineering bureau in Mytishi (Moscow region). The termination process is happening in Moscow in Tchernov facilities and by Tchernov employees. All connectors and solder are made in Taiwan by specialized company and according to specific Tchernov definition and requests.
What is the difference between the BRC and copper, used by other manufacturers?
Most of cable consumers think, that only pure copper without impurities can be used for the best performance in audio and video transmission. However, impurities, as we know, are always present, even in the pure copper. Our numerous tests proved that copper with right balance of impurities "perform" far better than most refined. Experimentally we found an optimal balance between copper and admixtures – BRC (Balanced Refinement Copper) – that lets the conductor, correspond to the sound transmission most correct.
Why you do not make flat cables, and only round?
All our conductors and cables are round. We see it as the most stable and natural from the point of view of the laws of physics, as well as providing a more uniform application of insulation materials.
What is the function, besides decorative, outer braid of cables?
Basically two advantages:
The jacket protection from possible mechanical damage during cable installation.
Improving the damping properties of the jacket.
What is the main function of a drain wire speaker cables, and what happens if the drainage is not connected to the "minus" terminal in the audio system?
The drain wire provides electrical contact to the shield along the entire length of the cable. If drainage is not connected to the "minus" terminal in the audio system, you can have the distortion in high frequencies, the sound is too bright, intrusive, and low-frequency range will be "blurred". When connecting the drain wire, the RF range will be more transparent, natural, and bass is more controlled. In general, the sound becomes more natural.
Where to ground the shield in the case of a balanced construction of your cables with RCA connectors?
Shields of all our balanced interconnect cables Series: Special, Classic and Reference, with RCA connector, grounded at the signal source.
Why do you recommend your cables lengths scheme?
The lengths of our cables are selected in accordance with the "golden ratio". The starting point in the calculation of the following lengths was the anatomical proportion of 62:38, which in addition gives 1.0, and at division of 62:38 - number 1, 6315787 (rounded to 1.65). Taking as a starting point 1.0 (based range - 1 meter), and following the principle of the golden ratio (length of the next segment should be equal to the sum of the previous two), we get the following range: 0.62 m - 1 m - 1.65 m - 2, 65 m - 4.35 m - 7.1 m *. Length 4.35m and 7.1m are slightly higher than the value of the golden ratio, associated with the wave’s proliferation in the cable and chosen experimentally. 3.1 m and 5 m - intermediate length, made at the request of consumers.
Why the relative high price of the entry level cable?
The price of our products is determined by quality of materials. Our lower line products use the same materials as in the premium series. The only difference is in the complexity of design and materials quantity. They also use only materials, tested and approved Institute of Cable Industry in Russia.

What is «Elastollan»?
Elastollan is special thermoplastic polyurethane elastomer (we use the one from BASF), which we use as jacket material. This is a unique material with great electrical, mechanical and high-damping qualities.
Why you don`t use a Teflon monolithic or foamed insulation?
Insulation with PTFE makes a conductor exposed to high temperatures. So we use the cold insulation in a multi-layer winding porous PTFE films, providing insulation without putting heat the conductor.
For what need the cable cotton filler and other cotton components?
It is necessary for damping of mechanical vibration, caused through electrodynamics effects in the Earth's magnetic field and the magnetic fields from different devices, and reduces microphone effect. This, in turn, greatly improves the cable work with small signals, and increases the resolution of the audio system.
PVC Jacket with antistatic additive. The purpose of this supplement?
Antistatic additive performs three important functions:
Reduces microphone effect, because of the smaller static voltage of the jacket during its deformation.
Reduces the cable sensitivity to the external interferences, because PVC does not accumulate static electricity.
Reduces the "warm-up" of the cable (the time of stabilization of its parameters).
Do I understand that in the "SPVC" is "S" indicates the presence of this additive?
The letter «S» means SOFT (soft) that initially of the mechanical properties of the cable.
Are you going to use the neutral polyvinyl chloride (NPVC) in any cables other than the Standard DC Power?
We are also using this material as a main jacket in our Classic XS SC and as an inner jacket in the Reference SC and the Ultimate SC.
Why you do not use silver plated conductors?
Based on our concept, copper is the best material for the audio signal transmission. As know, we use a Balanced Refinement Copper with a certain content of impurities. One of the impurities is already silver, that quantity is enough for that balance. Additional silver in our opinion distorts high-frequency range.
What is double layer jacket?
The inner layer of the cable jacket is made of unpainted plastic. The second layer - painted plastic. Despite the fact that we are using organic dyes and the impact of such dyes is minimal, impact and interferences are still possible. Therefore, the use of double layer with the following advantages:
The maximum reduction possible effects of painting concentrate on the cable composition.
Better damping, in contrast to the monolithic shell, which helps to protect cables from the effects of acoustic noise and vibration loads.
What is XS, and what is the fundamental difference between the longitudinal shield of aluminum or copper foil?
XS («X-Shield®») - developed by "Tchernov Audio" is a multilayer shielding of the audio cables, based on the use of two coils of copper foil as the inner and outer layers of the shields, and the braided copper wire BRC as an intermediate layer. In addition to protecting of the conductors from interference, «X-Shield®» reduces resistance of the shield and reduces the effect of stray current interference induced directly into the cable shield. The application of this shielding method for cables improves audio sound across the entire frequency range and significantly reduces the interference level and its influence to the parameters of the components.
You use two types of individual CAFPE® insulation: 2-layer and 3-layer. What is the main difference?
2-layer insulation was developed to increase both the dielectric and the mechanical insulation parameters in the cables with symmetrical construction with two twisted and insulated conductors. The improvement has been achieved thanks to the inner air-foamed PE overlay directly on the conductor (lots of air) and strengthening of the outer solid PE layer (protecting the cable from deformation when bent). We use 3-layer insulation in coaxial cables with only one conductor where its concentricity is critical.
Why do you use Semi-Air Tape Insulation SATI® only in the Reference and Ultimate products?
SATI® is a very complex, delicate and time consuming insulation to apply. It has expensive porous PTFE tapes as its base, which is why it is used in two of our most expensive cable lines. However, we also use the SATI® process in the Classic XS SC speaker cable, but using solid PE tapes instead.
What materials are used in the contact parts of your connectors?
In entry and standard level cables we use a gilded brass. In premium level cables we use only high quality copper plated with pure gold thickness of 7 and 10 microns.
What is the essential difference between the Reference AC Power and the other power cables in Tchernov Cable’s lineup?
In contrast to other our AC Power cables, in the Reference AC Power we have realized the principle of DSC (Distributed Symmetric Conduсtor). The energy transmission is carried out by two lines consisting of three similar conductors, configured around a central grounding conductor in a hexagonal structure (1+6) with maximum packing factor. This principle increases the cross-section by 80% in comparison to our other power cables and combined with the SATI®, SASDB® and X-SHIELD® SE technologies it provides the highest possible performance and the most efficient operation.
Is it possible to use your power cables for power cabling in building constructions?
Yes, it is possible. You can use it everywhere when you need a more flexible power cable.
The signal from power board in the house to the socket transmits by simple aluminum wires. Is there any use in Hi-End cables in your system?
The reason for these cables existing is that even to change the small piece of power cable in the distance between the power board and the socket and also between the socket and the component corrects the power line and provides a better basis for your audio or multimedia system.
