The MS112 is an XLR switching device. The MS112 will allow you to Push To Talk or mute an XLR signal with a selectable momentary or latching switch configuration. LED indicator for monitoring where the XLR signal is being sent. A mic or line level XLR is plugged into the input, and output is sent to the A or B outputs in a momentary or latching configuration. Quiet switching for both +48V phantom power microphones or dynamic microphones. This device momentarily mutes (or talks) a microphone or XLR signal between the A or B XLR outputs. This function is very handy in the event of a sneeze, cough, or other possible distracting noise. Or when you need to control when a mic is active for announcing or paging. Or when switching between two different outputs.

When it works, it's perfect. A switch with no pops and silent mechanical operation. But I've now had 2 of them fail. When switching from A to B (or in my case using it as a mic mute, from hot to mute), then switching back, the output fails and no signal passes back to A. In the first case it took several months before the failure occurred, but when I replaced it, the second one failed in exactly the same way on it's third use. Sadly, I can't rely on it.

An exceedingly simple electronic circuit built into a solid metal housing, that somehow manages to fail at its one job. No switching, nothing.
