PIP MOD for more power? Is there such a thing?
« on: May 18, 2019, 03:16:11 AM »
While trying to steer a friend in the right direction on powering DPA 4080's with the smallest from factor possible for  >:D situations, the idea came to me that - wouldn't it be great if someone offered a mod to the PIP on your M-10 or R-07 or what have you, so that the plug in power voltage would provide 8-ish volts instead of whatever the standard is (I think 4.5 or 5V is the highest PIP I've read about) and I think only 3V in most cases.
It sure would be nice to be able to plug your 4061's or 4080's straight into your deck and eliminate the extra cables and batteries that come with a battery box or external preamp.

recent testing indicates the official DPA equipment (d:vice and phantom>microdot adapters) provide 2.4-2.7V under load, the same as many PIP handhelds

max SPL TBD

Consider that this would burn batteries way faster.

A Marantz PMD620 supplies close to 5V on the mic input. Easier to use a deck that does it already than modify one that doesn't.

I have thought this as well. I would love to see a MOD for something like this.

R07 worked well with Microdot actives and full sized caps. Can’t imagine it wouldn’t power 4061s, will test

Wow! Really? That's awesome. What full sized caps?
I recorded Neil Young last night with the 4080's and an R-07, but ran a Church Ugly Battery box in between. Too nervous to rely just on the PIP. I will have to experiment with a loud show. Tedeschi Trucks is this Thursday and Friday. Maybe I'll run those 4080's straight into the R-07....

I've done this exact mod to my R07 so that it now supplies 9V PIP ... I velcroed a Church Audio Ugly Battery Box to the back  ;)

 Based on testing I’ve been doing I see different behavior from equipment that has identical PIP voltage. The waveforms at high SPL are somewhat asymmetrical, not really DC offset, but ‘clipped’ (more like amplitude challenged) but only on one side of the waveform it seems. I asked Doug about it and sent him some pictures of the waveforms and he said that it looks like the plug-in power is running out of current in such cases. So voltage doesn’t tell the only take. I’m not sure if we could even accurately measure current on transients to determine what the max is. I would think that a large capacitor might be able to buffer these transients but then you’re into a battery box anyway as you can’t just stuff large caps inside of most handheld cases

extreme example:
