Naiant IPA

How does an IPA work for mbhos? do i need 1 or 2? 

[Hypnocracy]

MBHO an Milab require two IPA's to run balanced...you can run one unbalanced...I guess

Here is my MBHO IPA setup

What I was hoping to do was actually get the mic cable modified by Jon and chop off the XLR connectors to replace them with mini-XLR then put the female end of the mini-XLR to the original large XLR so that I could have a small XLR-Mini XLR cable to plug into any phantom powered pre, or plug into the IPA cable.  (which would be female mini-XLR > IPA > 3.5mm male)

I seem to recall that the DPA compacts have electronics in the XLR connectors, so I don't think the second scenario (miniXLR > IPA) would work if you chopped them...

Yes, I'm pretty sure they do. The dpa4061s that I have use an adapter that definitely has electronics in it when plugging into XLR. But I use the same mics WITHOUT the XLR adaptor plugged into a 9v battery-powered CA ugly, and used them with a ca9100 for a while...

so shouldn't the DPA4021 set be able to be powered in a similar way?

I'm sure I will have to ask Jon all this, but honestly, every time I try to do something I get hit with all sorts of terminology I have to go look up later and it slows the momentum. I currently use this Schoeps CMR rig that was put together by hi and lo:

and I'd like to be able to pull this off with my dpa4021 set, replacing the tinybox with the Naiant IPA option.
I'm just not sure its possible without a lot of confusion on my part.

The IPA is a direct replacement for the Tinybox, so you could certainly use it with the 402x microphones (i.e. 402x > IPA > M10), but personally I would question the elegance of that solution versus running into a recorder that supplies phantom (i.e. the PMD-661, which I believe you already own). I also don't think it would be any better than your existing Tinybox.

Going back a few posts, I'm wondering why you find the 4021 > Tinybox setup burdensome? To me it sounds like a more elegant cabling solution is all that is required. As for the brickwalling, it shouldn't if you use the +4dB gain setting and you could even consider having that lowered to 0dB. What gain settings does it currently have?

the IPA doesn't supply 48v though correct?
The TB does and that right there is huge imo. I can run plug in mic, "actives", and 48v on the TB I own

I think you're right. Creating full phantom from an A23 battery doesn't really seem possible. Not sure if he has any other options, but yeah... it's not really a TB replacement if it doesn't provide phantom.

I thought there were 60V versions of the IPA? If so, it would seem 48V would be available.

+9V to +52V phantom power

[hi and lo]

I'm pretty sure that's the input power.

Phantom power and polarization voltages are very different. Phantom is 48v and specced for up to 10mA current draw. Polarization voltage (I.e 60v) has a minuscule current draw. You can measure it micro amps or less, which is why you can power it using an A23 battery.

No P48 with the IPA!! 

[noahbickart]

Has anyone powered their IPA from an external, non phantom source using the DC in?
If so, how have you done it?
Plug size on the IPA?
Good small battery pack? Perhaps USB, I think the IPA can run on 5v.

The A23 battery is great for stealthing, but I'd love to use my KCY IPA for channels 5/6 on my Mixpre6, and I want to bury the thing in my bag and use with a rechargeable battery. Any leads?

I have been curious about this also but the details are not clear to me


From naiant.com "about the 2017 IPA"

– A 5V-12V converter cable enables use of 5V USB battery packs with the IPA. 5V packs can be cheaper and smaller than available 12V external packs, so this cable will offer the smallest possible external battery pack solution.

So you need a special cable to use 5v? I would use 12v anyways but...


On the page where you order a IPA:

The external power jack is 1.7mm ID, 4.4mm OD, center-positive.  A compatible power supply is available on the X-R accessory menu.

- there is a $9 option for a 12v power supply on the X-r accessory menu but I assume this is a 12v power supply you plug in. Can any 12v power supply be use as long as you have a cable with the correct size connector?

[noahbickart]

Yeah, I was hoping for a dc plug to USB cable to use with the same USB-C + USB-A battery I use with my mixpre6.

I wonder if ted could wire something up....

[jahorro]

I asked Ted to build a custom cable 4.0mm x 1.7mm (to power the IPA) to 4.75mm x 1.7mm (plugged into my 12V external battery - Fotodiox Turbopack 9000 Power Pack).

This external battery successfully powered up my IPA, which supported my KCY > Neumann AK40 caps (KCY cables built by Nick).

I've used this set up nicely for a few recordings over the last few months.
