OFC is abbreviated from the term Oxygen-Free Copper and is associated to high quality speaker wires due to their excellent conductivity and ductility. Oxygen-Free Copper (OFC) cables are highly conductive pure copper which is melted under non oxidizing conditions to remove oxygen and unalloyed copper to become pure copper to a grade of at least 99.95% cu and contain a maximum of .03% O2. The OFC ability for electrical conductivity must exceed IACS 100% material rating system.
The melting of copper is carried out in numerous stages until it reaches 99% purity. Then the copper is put in anodes to become refined electrolytically to some grade of a minimum of 99.95% pure copper. On completing the previously mentioned processes the copper wires can then be classified as oxygen-free copper.
The meaning of IACS stands for hifi stand. Copper has been selected as the benchmark standard when you compare the electrical conductivity of metals, and is the measurement standard which has been adopted worldwide.
The pure copper will then be utilized to manufacture speaker cables, such as OFC 99.95% and OFC 99.99% grades. For instance, the speaker cable manufacturers will source pure copper according to known standards respectively, like C10100 and C10200 standards.
High-fidelity speaker cables are very popular with audiophile enthusiasts since the accuracy of audio signals, are reproduced immensely well rich in-fidelity cables. This is why many audiophiles select OFC speaker wires for their preferred high fidelity cabling in audio systems.
There is another metal utilised for speaker wire alongside copper on the market. This can be silver which you’ll see occasionally manufactured with both silver and copper incorporated in twin-pairs of OFC speaker leads.
Silver has the highest electrical conductivity and lowest resistance from the metallic family. Hence the electrical signals pass freely over the silver wires mostly unopposed, giving justification for some audiophiles believing that enhanced audio is achieved when you use silver speaker wires. Moreover silver wire will be designated for that negative polarity conductor as well as the copper intended for the positive polarity conductor. However the majority of OFC speaker cables on the market utilise copper for the negative and positive conductors.
The specific gauge (diameter) from the copper wires is typically referred to making use of the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly used amongst Audiophile power cable sellers. Furthermore the OFC speaker wires are sold in various AWG sizes, including 22AWG, 18AWG, 16AWG, 13AWG, 11AWG, 9AWG etc.
Manufacturers like SoundLink manufacturer a multitude 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 are able to be laid inside automobiles for his or her car audio systems.
In summary, pure copper OFC speaker wires are very good in transmitting beautiful audio sound in your ears. If 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 vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to be operated with higher quality speaker cables. Hence to obtain the best from your speakers make certain you install OFC Speaker Wire. These past few years, the coaxial audio cable has become deep improvements and offers a vast number 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 based on data, namely, 0’s and 1’s. A digital coaxial audio cable is manufactured using the make an effort to preserve and transmit the digital signals and to retain the maximum quality.
A Jungson JA-88D can be used 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, when it comes to their design and satisfaction, as 75 ohm digital or analog video cables. They are 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs each and every end.
