OFC is abbreviated from the term Oxygen-Free Copper and is assigned 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 some 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 performed in a number of 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 aforementioned processes the copper wires can then be considered oxygen-free copper.
The meaning of IACS means hifi table. Copper has become selected because the benchmark standard when comparing the electrical conductivity of metals, and it is the measurement standard that 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, such as C10100 and C10200 standards.
High-fidelity speaker cables are incredibly popular with audiophile enthusiasts considering that the accuracy of audio signals, are reproduced immensely well with higher-fidelity cables. This is why many audiophiles select OFC speaker wires for 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 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 utilizing silver speaker wires. Moreover silver wire will be designated for the negative polarity conductor as well as the copper meant for the positive polarity conductor. However nearly all OFC speaker cables on the market utilise copper for both the negative and positive conductors.
The particular gauge (diameter) from the copper wires is normally referred to using the American Wire Gauge (AWG) measurement system. The AWG measurement product is commonly used amongst hifi Audio RCA cables sellers. Furthermore the OFC speaker wires are offered 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, along with, in round wire shape bpiygi a flat wire contour around neatly fit under carpet. The flat-designed OFC speaker cable may then be laid inside automobiles for car audio systems.
To conclude, pure copper OFC speaker wires are incredibly good in transmitting beautiful audio sound for 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 blown away.
The vast majority of audio surround systems and home theatre manufacturers built their electronic music devices to become operated rich in quality speaker cables. Hence to obtain the best from your audio system make certain you install OFC Speaker Wire. These past couple of years, the coaxial audio cable has got deep improvements and provides a huge variety of cables made for the best fit. Today’s audio devices don’t use analog signals to produce sounds, as 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 the aim to preserve and transmit digital signals and to maintain the highest possible quality.
A Jungson JA-88D can be used to convey multichannel audio content from sources including DVD players and satellite receivers to other devices which can decode that content, such as A/V receivers and DACs. Coaxial audio cables are the exact same, when it comes to their design and gratification, as 75 ohm digital or analog video cables. They are 75 ohm characteristic impedance, RG-59 style cable, with gold-plated RCA plugs at each end.
