Speaker cable GCG-10/4
Cross section of conductors – 4x2.5 (2x5.0) mm² Ag - mono
Speaker cable with symmetrical structure consisting of 4 veins (conductors) in a Star-Quad system (four stars), each of which has the 31 polished silver wires Ø 0.32 with 99.999 (5 N) standard. Insulation of the first contact to the conductive beam is Teflon and air space geometrically created as a result of belting with Teflon PTFE tape. "Star-Quad" conducting system creates an electromagnetic field interactions, so that the internal crosstalk is reduced. Shielding is tinned OFC copper braid. Due to the shielding, the cable is polarized by an additional cable with OFC copper braid, called "pig-tail".
Additional cable with circuit elements of needle and bracket connects the cable shield with metal casing of the amplifier, giving a possibility of potential equalization (equipotentiality) of the screen with a plate of intermediate mass ie the metal chassis of the amplifier. The system of conductors (Stars-Quad) enables creating "by-wiring" connection. Cables are packed in brass gold plated forks and banana plugs and optional (recommended) Argentum silver fork with or without plating and with coverings of gold (Au) and rhodium (Rd). Junctions are made Argentum alloy (Sn/Ag 8% silver). The outer shell is steelon blue braid with five red interlaces, what is characteristic of this cable.
For each speaker cable is included about 1.5 cm cable sample.

Equipotentiality of the screen's speaker cable
Speaker cables from the connection to the amplifier, have additional cable (so-called "pig-tail"), through which we connect the speaker cable screen with zero reference potential, which in this case the amplifier chassis. The current standards of the speaker sockets do not include EMC phenomena. French expert /Alain Charoy - Electromagnetic compatibility/ says that no connection to the cable shield with the zero reference potential does nothing (apart from reducing the internal differential crosstalk). Quote reads as follows: 'The screen with no EMC connections is like a waterworks pipe which is open on both sides", so if we use cable shielding is a need to ensure that secondary disorders causing disturbances in the useful signal, are prevented from. So the screen must have the potential equalization - a pity that this subject is so far treated with neglect by the audio cables and electronics manufacturers. If we assume hypothetically that in our environment there is no electromagnetic disturbances, the shielding would be unreasonable, but of course this is not. A current very rapid development of technology causes a systematic increase in their level. The correct connection is verified (plug the network cable of the amplifier pulled out of outlet 230 V) using the probe, which is an optional speaker cables. Check the continuity of the conduction using the sampler ie by putting the sampler tip to the needle with one hand and one touch uninsulated parts of the amplifier (for example, it may be uninsulated screw amplifier chassis) and, if properly connected, the indicator will light up the sampler.
