Sometimes it is much nicer to allow participants to be able to mute the
mics themselves without having to catch the eye of the node operator.

Has anyone built (or bought) a hardware mute button for the DB25
control/status port of the gentner?

It looks like all you need is a 5v led between pins 4 and 25 and a push
button between 3 and 25 (or maybe 24?). You could program the pins
differently but this looks like the default.
