When it comes to wiring for anything, the specifics depend on the devices involved and the overall requirement. Audio cabling, in particular, has two basic analog cables, XLR cable, and RCA cable. These are largely for very different scenarios.
The connector on the XLR cable has three pins, whereas the one on the RCA cable only has one. XLR passes balanced audio whereas RCA passes unbalanced audio. This is also where the use case bifurcates. XLR connector also has a latch on it to lock the connection in place. RCA has no such clasp.
Let’s take a look:
Home Theatre Setup
For a home theatre setup, you need a decent or high-end TV for display, preferably one that has an OLED or QLED panel. But the display is not the only important part of the setup. These TVs generally don’t have the best audio output for optimal movie watching. For surround sound, you can connect up to eight audio channels via RCA cables. This can make your movie-watching experience more enjoyable, with the sound of every soft footfall in a horror movie and all the notes in a musical.
Audio Editing
If you want to edit audio, you want to be able to listen to it in stereo. Headphones that have RCA connectors are capable of handling stereo output. You will need a computer that has the left and right stereo channel RCA ports. If you are able to hear with accuracy, you will be able to make the edits accordingly.
Recording Studio
Here, you need balanced audio. The sound mixer has audio coming in from the microphone via an XLR cable. This produces significantly less noise in the audio transfer, thus giving purer, high-quality output. This recording can go for mass-market consumption through various mediums like music streaming services, CDs, vinyl records, etc.
