Coaxial digital audio cable – With Phono RCA plugs
Digital coaxial audio cables with 75 Ohm impedance for digital audio transfer with Phono RCA plugs and are often used between CD player and amplifier.
Large selection of coaxial digital audio cables and accessories. A digital coaxial cable can be used for digital audio transmission between a Media Player, settop box, DVD or CD player to an amplifier or soundbar. Unbalanced digital audio cables are either equiped with RCA- eller 3.5 mm. Jack connector.
For transmission of a unbalanced digital audio signal with a coax cable, it is important that the cable has an impedance of 75 ohms and is well shielded, to avoid reflections in the cable, and noise that can ruin the timing of the signal and cause jitter (electronic noise) in the sound. The same can occur in an optical cable, only here it happens in the transition from an electronic signal to an optical one. Professional digital audio cables, however, are balanced and use a 110-ohm cable with XLR connectors, which is even more resistant to noise.
There are many different opinions about whether digital coaxial or optical cables are better, but our recommendation is to use coaxial cables for short routes in particular, and where the sound quality is important. For long cable routes, optical cables have certain advantages as there is not much resistance in a fibreoptic cable, compared to a coaxial one. However, this must be balanced against the potential losses in the transition from electric to light and back again in the devices to be connected. All this is primarily important to have in mind for high-end systems. When connecting regular receiver boxes, cheap DVD players, etc., you should consider what is the best solution in practical terms and the available connectivity.
What are Mini Toslink cables used for?
For connecting, e.g. laptops, Google Chromecast Audio with SPDIF output, often a combined stereo and optical output are used, in the form of a MiniJack/MiniToslink connector. To connect such devices to a digital system, MiniToslink - Toslink cables is used.
