Got the MVi. First thing that raises an eyebrow is that it is NOT internally powered by a battery. Therefor, it relies on whatever voltage/current it can muster from the very starved power supply of an iPhone's Lightning jack. It's phantom power output rating is only 12 volts, as a result. I take that has not been an issue for your particular mic, Bish?
I hope to try it with different mics and see how they behave.

Not a scientific test by a long shot... but I'm actually on the road at the moment so I've had a chance to try my new "mobile rig" for auditions. Jen's closet is set up with pegboard mounted auralex and a few quilts & blankets... currently using an MXL 2003a and a X2U into Audacity... apart from having to sort out Audacity having a hissy-fit with the X2U, the sound isn't too bad.

I set up with the MVi and Bruce's old AT875R into the iPhone 6+ loaded with Twisted Wave. The sound quality was really quite good... I used the flat setting and reviewed and edited using the trusty old Sony 7506 cans. There is definitely a significant additional drain on the iPhone battery when using for an extended length of time (I left it on for a couple of hours just to see). I would expect to start recording with a full battery, so the (approx) 10-15% hit my battery took was not a problem. I also edited via the MVi simply because the chunky 7506 plug wouldn't fit directly into the iPhone because of the case.

Bottom line... I sent it off to our favourite agent (Erik) with a request for comment on the quality... "pretty good" was the verdict. The only thing I have to work on is editing on a phone... but that's just practice I guess.

I have no idea about the power requirements for the 875, but it seemed to work well. When I get home I'll give it a go with the e100s and the 416 just to see what happens.

Scientific or not, it was certainly in-depth! Thanks, Bish!

Just got the Mvi yesterday, had a chance to play with it today,…

1) Recording to Twisted Wave and an iPHone 6, It does NOT work with a 416.. at least not for me.. tried different cords, etc.. in and out of Airplane mode.. very staticy and a hum.. bummer
2) Neither did it work with an Sm7b with a Triton FET head..
3) It does, however work wonderfully with the AT 875r and the iPhone..used the flat setting and touch of EQ in TW
4) Worked with AKG Perception 220 pretty well… just barely enough gain for the AKG however..
5) Worked surprising well with a crappy ATR 2100, which is cardoid dynamic similar to a SM 58..

I recorded about 5 or 6 auditions with the AT 875r, so we'll see how it goes..have yet to hear back on any

I checked out a few things, and I think the issue might be the voltage of the phantom power. George mentioned this also.

The 416 requires 48v + or - 4v and uses 2mA
The 875r requires 11-52v and uses the same 2mA

The MVi puts out 12v in iOS mode and only puts out 48v when plugged in via USB. It doesn't specify if that includes USB OTG.

So any mic that either doesn't require Phantom Power OR that will work with 12v Phantom Power should work. I'd be curious if an older 415T (that used 12v) would work with it. Any dynamic mic should work fine (providing there is enough gain).

For any interested parties, George's review of the MVI has gone live!
