Optogate PB-05 M

Optogate PB-05 M Automatic Microphone Switches have been around for over a decade!

This gadget is the top special request from lead vocalists doing live performances to their primary touring companies, audio production companies, sound engineers, & audio technicians.

We suggest for every wired vocal microphone on stage to put an optogate on it! 

This optogate model PB-05 M :

  1. attaches through the back of the mic through the 3 pin XLR male and female attachment areas. 

  2. No batteries or extra cables required -it is phantom powered through your mixer. 

  3. Includes tool to set the proximity sensor distance to the musicians vocal technique.
  • now when musician is ready to sing

“Mic ON”

  • when musician needs a break or needs to chat to someone else

“Mic OFF”

(About -42 db)

  • There is now Less possibility of feedback in your unused open mics. 

  • Greater control of stage volume
  • Perception of increased headroom capacity in amps and FOH monitors.
  • Sound Clarity everyone will love


From music artists themselves to Front Of House (FOH) , Music Directors (MD’s), Worship Leaders, and yes your live audience demand you get enough automatic mute switch Optogates to improve sound clarity & heal the bleed. ( we don’t wanna say “kill the bleed” because we wanna bring life to your productions & performances) .

When musician is in range of sensor : Mic is On
When musician is out of range of sensor:  Mic is off. 

– 42 dB attenuation, effectively turning the mic off.

– XLR 3-pin connectors (1 = gnd, 2 = plus, 3 = minus)

The PB-05 is available in 2 versions.
