OFC is abbreviated from the term Oxygen-Free Copper and is assigned to high 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 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 carried out in numerous stages until it reaches 99% purity. Then the copper is positioned in anodes to become refined electrolytically to a grade of at least 99.95% pure copper. On completion of the previously mentioned processes the copper wires are able to be considered oxygen-free copper.
The definition of IACS means hifi table. Copper continues to be selected because the benchmark standard when comparing the electrical conductivity of metals, and is the measurement standard that has been adopted worldwide.
The pure copper is then used to manufacture speaker cables, like OFC 99.95% and OFC 99.99% grades. As an example, the speaker cable manufacturers will source pure copper according to known standards respectively, including C10100 and C10200 standards.
High-fidelity speaker cables are extremely favored by audiophile enthusiasts considering that the accuracy of audio signals, are reproduced immensely well with high-fidelity cables. This is the reason many audiophiles select OFC speaker wires for his or her preferred high fidelity cabling in audio systems.
There is 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 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 to a few audiophiles believing that enhanced audio is achieved when utilizing silver speaker wires. Moreover silver wire will be designated for that negative polarity conductor and the copper designed for the positive polarity conductor. However the vast 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 described utilizing the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly used amongst hi-fi speaker cable sellers. Furthermore the OFC speaker wires can be bought in several AWG sizes, like 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 contour around neatly fit under carpet. The flat-designed OFC speaker cable are able to be laid inside automobiles for their car audio systems.
In conclusion, pure copper OFC speaker wires are incredibly good in transmitting beautiful audio sound in your ears. If you have a nice home theatre system with digital Dolby Digital and quality speakers then install OFC speaker cables and you’ll be very impressed.
The majority of audio surround systems and home theatre manufacturers built their electronic music devices to get operated with high quality speaker cables. Hence to get the best from your audio system make certain you install OFC Speaker Wire. These past couple of 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, because the old ones did, but use digital signals derived from data, namely, 0’s and 1’s. The digital coaxial audio cable is manufactured with all the try to preserve and transmit digital signals and to keep up with the maximum quality.
A Jungson Impression II CD player is utilized to convey multichannel audio content from sources like DVD players and satellite receivers with other devices which could decode that content, for instance a/V receivers and DACs. Coaxial audio cables are precisely the same, when it comes 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.
