Brides 2 friends are doing the first dance next week: 1 singing, one playing the guitar. I've been asked if I have a spare mic, and can the guitarist plug into my system. I've said yes (I must be getting soft in my old age).

Question:- As I've never plugged any instruments directly into my mixer (Denon x500) - is there anything I should be aware of? Anyone ever experienced an issues with musicians equipment ran through a DJ mixer? It'll be connected via a 1/4 jack to phono.
