Technical dictionary :

 

  • 4N – 6N =  indicate the purity of conductor and using of other metals in wire

 

                  

  • 4N = 99,99% 

  • 5N = 99,999% 

  • 6N = 99,9999%

 

  • UP =  ultra pure - free of any other metals

 

  • OFC =  oxygen-free copper free of oxygen molecules that degrades the metal  and makes the conductivity worser

 

  • OFHC = oxygen-free high termal conductivity copper OFHC has better conductivity than silver

 

  • OCC =  copper with highest purity of inner structure - Ohno Continuous Casting is the best manufacturing process that creates perfect solid surface of metals especially for copper and silver

 

  • Silvered Copper =  copper - additionally coated in silver to create better electrical  conductivity and protection against extraneous influence of any kind especially oxidation

  • PTFE =  conductor wire coated in teflon jacket teflon is the best dielectric material used for electrical wiring as protection against mutual induction of wire

 

  • FPE dielectiric = foam filled with nitrogen gas creating the clean fluid  power energy transfer

 

  • Conductive PVC =  create an electrostatically charge to prevent the signal  induction between shield and conducitive wire

 

  • Cotton filling =  cable wires tightly binded in cotton fibre to eliminate any vibrations  and inductions within the wire

 

  • Cable Shielding =  necessary additional layer of protection jackets as aluminium foil  and copper wire braid to prevent any electromagnetic interference  (EMI) or other RF interferences that can enter the cable and „harm“ the signal  while avoiding radiation force field coming from the cable itself to “damage” the signal in other cables

            - the shield is connected to the protective (ground) wire on the socket side or the signal - output side of the the unit

            - this option is more suitable when using also additional devices like power bar passive filter, isolation transformer, mains                            conditioner or other filtering units

 

  • Cable Filtering =  additional layer of protection jackets as aluminium foil  and copper wire braid is using for cleaning (elimination, filtering) of transfering electrical signal from 50 Hz and 60 Hz „hum“ coming from electrical mains and sockets and signal interferencies between devices coming fro m induction between the cable wires 

            - the shield is connected to the protective (ground) wire on the signal - input side of the unit or in IEC header

            - this option is more suitable when NO  active or passive filtering is presented in stereo set-up or NO  power unit provides                            filtering option

  • Cable geometry =  method of assembling the wires in final cable that helps to  eliminate the interferences and internal wire induction

 

  • Cable direction =  method of attaching the copper braid shielding to prevent hum between the device dictate also the way of the correct pluging a connector by the direction of transfering signal from the signal source to an amplifier

 

  • 75 OHM characteristic =  resistance of conductor wire obligatory prescribed for digital transfer of 0 and 1 to prevent hum and Jitter  very often clearly ignored by standard producer

 

  • Jiiter =  deviation process that change or degrade the periodicity of signal transfer which cause another amount or another arrangement of incoming date

 

  • single-wiring =  using one pair of connectors on a loudspeaker and a single cable  (two conductors) running from the amplifier output to the terminals at  the loudspeaker housing

            

  • bi-wiring =  using two pairs of connectors on loudspeaker and two cables running  from the same amplifier output to the speaker cabinet – one for the high  frequency or tweeter driver and one for the low frequency driver (through  two separated crossover filters) to reduce magnetic interaction in the cable resulting in better sound

 

 

  • bi-amping =  using of separate amplifier for each driver to improve the separation of  signal frequencies

  • burning period =  time of transferring electrical current or continuous signal transmission until the cables achieve their full sonic potential mainly because of changing induction values between dielectric materials and wire conductors
