Coaxial Digital Cables
Coaxial digital cables are the most common type of connection cable used for digital audio. They look similar to the RCA cables that many people use and are familiar with. The only difference is that it carries digital signals instead of analog signals.
These cables look very similar to standard analog RCA cables. They are thicker than RCA cables and are shielded just like regular cable TV coaxial cables. The interference from outside signals is minimized with greater shielding.
Coaxial digital cables transmit digital signals in pulses of electricity. They consist of copper wires shielded from interference with the help of surrounding aluminum wraps. The wires are housed in a strong outer case. Coaxial digital cables used for audio applications have an impedance of 75 ohm, which means they can handle considerable energy. Also, they have a larger bandwidth than a normal RCA cable. For an affordable digital audio cable that delivers premium sound, coaxial digital cables are an extremely attractive choice.
