Shure Microflex MX400SMP User Manual

Button Configuration
For logic control operation, DIP Switch 1 determines the button be-
havior (DIP Switch 2 has no effect).
Button Behavior DIP Switch Setting
Momentary: When pushed, SWITCH OUT
(red wire) falls to 0 V. When released,
SWITCH OUT returns to +5 V.
Toggle: Push and release sets SWITCH
OUT to 0 V. Push again to toggle back to
+5 V.
Controlling the LED Using Logic LED IN
When configured for logic mute control, connect the LED IN con-
ductors to an external switch, relay, or a TTL gate (gate out) on an
automatic mixer. The MX400DB contains an internal pull-up resis-
tor circuit.
• The LED illuminates green/red when the MX396 LED IN is
grounded (orange wire connected to the green wire).
• The LED illuminates red/off when LED IN is lifted (orange wire
is NOT connected to the green wire).
