OFC is shortened from the term Oxygen-Free Copper and is associated to high quality speaker wires because of the excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper that is melted under non oxidizing conditions to get rid of oxygen and unalloyed copper to become pure copper to some 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 conducted in several stages until it reaches 99% purity. Then the copper is put in anodes to get refined electrolytically to a grade of at the very least 99.95% pure copper. On completion of the previously mentioned processes the copper wires are able to be classified as oxygen-free copper.
The definition of IACS stands for hifi racks. Copper continues to be selected since the benchmark standard when you compare the electrical conductivity of metals, and is also the measurement standard which has been adopted worldwide.
The pure copper will then be utilized to manufacture speaker cables, including OFC 99.95% and OFC 99.99% grades. For example, the speaker cable manufacturers will source pure copper in accordance with known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are very well-liked by audiophile enthusiasts because the accuracy of audio signals, are reproduced immensely well with higher-fidelity cables. For this reason many audiophiles select OFC speaker wires for their preferred high fidelity cabling in audio systems.
There exists another metal utilised for speaker wire alongside copper on the market. This 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 in 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 you use silver speaker wires. Moreover silver wire will likely be designated for your negative polarity conductor as well as the copper designed for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for the negative and positive conductors.
The actual gauge (diameter) of the copper wires is usually known as making use of the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly used amongst hifi power cable sellers. Furthermore the OFC speaker wires can be bought in various AWG sizes, including 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer a wide variety of the AWG sizes mentioned previously. SoundLink construct the OFC speaker cables with clear see-through jackets, in addition to, 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 their car audio systems.
To conclude, pure copper OFC speaker wires are extremely good in transmitting beautiful audio sound to your ears. In case you have a great home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables and you’ll be blown away.
The majority of audio surround systems and home theatre manufacturers built their electronic music devices to get operated with higher quality speaker cables. Hence to get the most out of your speakers make certain you install OFC Speaker Wire. These past few years, the coaxial audio cable has got deep improvements and offers a huge variety of cables designed for your best fit. Today’s audio devices don’t use analog signals to create sounds, since the old ones did, but use digital signals produced from data, namely, 0’s and 1’s. Digital coaxial audio cable is manufactured with all the aim to preserve and transmit digital signals and to keep up with the highest possible quality.
A Jungson JA-88D is utilized to convey multichannel audio content from sources including DVD players and satellite receivers to many other devices which could decode that content, for instance a/V receivers and DACs. Coaxial audio cables are the exact same, in terms of their design and performance, as 75 ohm digital or analog video cables. They may be 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs at every end.
