But if it got some hissing sound from the mic ports somehow even when you're not playing any music, please don't worry. It's just the magnetic interference with your own microphones, which is mainly caused by the Condenser Microphones, hence we suggest using Dynamic Microphones instead. Or put a magnetic block in there then the hissing sound will be gone.
