Lots of DJs don’t realise that that weird looking mic jack on the club mixer or their own gear actually could get them out of a hole one day, because it fits not one but two types of microphone plug – even your headphones at a push!

Fact is that a lot of mid-tier and high-end DJ controllers and mixers have microphone inputs onboard, and most of them have what’s called a combo XLR / TRS mic socket (sometimes called an omni socket). It basically lets you plug in a microphone whether it’s got an XLR jack (the one with three pins) or a 1/4″ jack.

Keep this in mind the next time you’re at a gig and you need to plug in a mic to the mixer or your controller: first check what kind of socket it has. If it’s a combo socket, you’re in luck. If it’s only either an XLR or a TRS (1/4″) jack, you need to find the appropriate lead to hook your mic up.
