When it comes to mixing desk’s, whether recording at home or in a studio, they all do the same thing. A mixing desks sole purpose is to take analog signals from microphones and instruments, and convert them to digital signals for your computer to pickup.
They range in price and physical size massively. The main difference between them is the number of inputs and outputs, therefore it totally depends on what you’re after to get the right mixing desk for you. It’s likely that you’re just getting started with home recording and a quick search on Amazon shows you can get started in this area for £40.
