NC3FXS is a handy connector to help turn any dynamic microphone into a mic with an on-off switch.
Best used to ensure a DJ mic never feeds back again while the band goes on to do their set!
Note: if you’re running phantom power to a condenser mic, this may cause a very nasty bang through your system, so ensure it’s only used with a dynamic microphone.
