MS112 XLR A-B switch
- XLR female input and XLR male output jacks
- Selectable Momentary or latching
- Status indicator to let you see what output is active
- Bottom panel screw holes for convenient mounting
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 dierent outputs.
OPERATION: To mute or send a microphone signal, connect the balanced XLR cable to the female input jack on the MS112. Connect
the male XLR output jacks to your next devices. Press and hold the switch for the amount of time you want the signal sent to the A out-
put. To hear the mic signal again on the B output, release the switch. The MS112 can be congured to “push for momentary” or “Push
for latching” by selecting the internal switch. The switch can be accessed from the side of the MS112.
Switch for changing the
orientation of the MS112
from a latching switch to
momentary. Momentary or latching
switch.
XLR jacks: Female input, Male outputs.
