Mute Switch for guitars, instruments, and mics (XLR and Hi-Z)

[nieko1313]

very interesting,have you tested it in the phono area.& had feed back? > DjZ-Switch

@nieko1313 By phono, do you mean turntables and IPODS? If so, I have not tried it that application. However, it should work as well. This mute switch works on condenser mics which are more sensitive than many other applications. By feed back, are you talking about responses or feed back in a PA system?

Great job!!! I watch all your vids...Keep them coming!!!

@primitiveprime Thanks! It looks like you have some great stuff on your channel also!

Hi I built a copy of your circuit and it works great for eliminating switch pop and plugging and unplugging dynamic mics. However, I am finding that plugging and unplugging phantom powered mics still gives a loud pop. Does this happen with yours?

@mrsamskey Phantom power is a tricky but easily fixed issue. There is a voltage balance problem between Pin2 & 3 on the mixer side of the circuit. This is because the 150ohm resistors are not matched perfectly. To eliminate the problem, the voltage on the mixer side has to be perfect for Pins2&3. Remove the 10K resistor and insert a 5K resistor in series with a 5K linear trim pot. Adjust the 5K pot until the voltage at Pin2&3 is exactly the same and/or adjust it until the pop goes away.

@mrsamskey Also, be sure you are plugging and unplugging the mic on the Female XLR side of the circuit. If you unplug on the mixer side, the capacitors are not protecting you. Basically, you are causing a bounce between the pins on the mixer side. Only the mic input is protected.

Thank you very much, this was really helpful!!

I can't find anyone who makes anything like this on the market in an A/B/Y/Mute. Excellent excellent tutorial.
