I'm looking to make a momentary push-to-talk switch that handles phantom-powered mics without popping but can also work with dynamics. Is such a thing possible?
Was thinking of putting it in a direct-box sized enclosure with an XLR in/out and a large momentary pushbutton on top.

Any circuit ideas would be helpful, I'm not having much luck as most pushbuttons are SPST and I get ticking even with dynamics and no phantom involved.

I've found many push-to-mute and a/b toggles online but very few if any push-to-talk, -and not necessarily looking for a footswitch either

Thanks

That will do, thanks!

Is there a place to browse all the banner ads on this site? Mine seems perpetually stuck on CobraSound.com and I never found that AudioMan product with google searching.

Also much DIY activity by audio hobbyists is more educational than actual product development. With this in mind, along with the time I've already spent tinkering with a pile of parts on my workbench, how do they make a phantom powered mic not pop when engaged?
(Google either isn't helping much or I'm not using the correct search terms)

Craig,

Unfortunately there is not, but AudioMan is not an advertiser anyway. We sell our ads directly, and have just finished contracts with a bunch of advertisers. We have a bunch more scheduled to start in March, but until then we're stuck with our house ads - which we provide to Cobra Sound as Jeff does a lot of behind the scenes web server work for us.
 
Note that you don't create a non-polarized cap by putting 2 electrolytics in parallel. They have to be in series.
2 2200uF in series, opposite polarity, is the correct way to create a 1100uF np cap from 2 electrolytics.
Doing what they suggest at best won't work, at worst will explode the caps.
