OFC is shortened from the term Oxygen-Free Copper and is associated to good quality speaker wires because of their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper which is melted under non oxidizing conditions to get rid of oxygen and unalloyed copper to become pure copper to a grade of at least 99.95% cu and contain no more than .03% O2. The OFC ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is performed in numerous stages until it reaches 99% purity. Then this copper is positioned in anodes to get refined electrolytically to some grade of at least 99.95% pure copper. On completion of the previously mentioned processes the copper wires can then be considered oxygen-free copper.
The definition of IACS is short for hifi racks. Copper has been selected since the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard which has been adopted worldwide.
The pure copper will then be used to manufacture speaker cables, including OFC 99.95% and OFC 99.99% grades. For instance, the speaker cable manufacturers will source pure copper according to known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are incredibly popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well with higher-fidelity cables. For this reason many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There is certainly another metal utilised for speaker wire alongside copper on the market. This really is silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of OFC speaker leads.
Silver has got the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely along the silver wires mostly unopposed, giving justification to some audiophiles believing that enhanced audio is achieved when using silver speaker wires. Moreover silver wire will be designated for your negative polarity conductor and also the copper meant for the positive polarity conductor. However the majority of OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The actual gauge (diameter) of the copper wires is normally known as utilizing the American Wire Gauge (AWG) measurement system. The AWG measurement system is widely used amongst hi-fi speaker cable sellers. Furthermore the OFC speaker wires are offered in numerous AWG sizes, such as 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer numerous the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, as well as, in round wire shape bpiygi a flat wire shape to neatly fit under carpet. The flat-designed OFC speaker cable can then be laid inside automobiles for his or her car audio systems.
To conclude, pure copper OFC speaker wires are incredibly good in transmitting beautiful audio sound in your ears. For those who have a good home theatre system with digital Dolby Digital and high quality speakers then install OFC speaker cables and you’ll be very impressed.
The vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated with high quality speaker cables. Hence to obtain the most out of your speakers make certain you install OFC Speaker Wire. These past few years, the coaxial audio cable has become deep improvements and offers a huge variety of cables made for the best fit. Today’s audio devices don’t use analog signals to generate sounds, since the old ones did, but use digital signals derived from data, namely, 0’s and 1’s. A digital coaxial audio cable is manufactured with all the try to preserve and transmit a digital signals and to keep up with the highest possible quality.
A Jungson JA-88D is utilized to convey multichannel audio content from sources such as DVD players and satellite receivers to other devices which could decode that content, like a/V receivers and DACs. Coaxial audio cables are the exact same, with regards to their design and satisfaction, as 75 ohm digital or analog video cables. These are 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs at each end.
