While analogue cables remain the traditional choice par excellence, technological advances have allowed the market to expand and diversify. In the case of digital cables, the most important thing is to understand what type of cable you are buying and how it suits your needs.
Analogue cables. Analogue cables are characterised by specific electrical (or, in this case, audio) wave balancing functions. The advantage of these cables is that you will only find three types of connectors: XLR male, XLR female and TRS, the latter being a version that fulfils the function of both input and output.
Digital cables. Digital cables tend to cover a much more diverse conduction spectrum, focusing on specific input and output sources. In the case of audio, there are three connectors that are most useful for linking the audio interface and the computer: USB, Firewire and Thunderbolt.
