I was asked to modify a simple microphone xlr male to xlr female muting box for a customer at the store I work for. The customer asked for an LED to be installed, showing the state of the selector switch-mic on or muted. There is a DPDT footswitch on it where half the switch is made use of. Pins 2 and 3 of the XLR connectors are shorted together to mute the microphone. A phantom-powered microphone will not be used but the customer asked for the LED to be powered by the phantom power supply on his mixer. Is this feasible? Using the unused section of the footswitch's spst contacts and resistors in series with the LED, plus a resistor to cut down the 28 to 40 volt phantom supply, causes popping sounds when the switch is pressed. [of course!] Do you think that there is a way to do this without causing any noise in the microphone's mixer? Thank you for any help you can give. Len.
