What's the problem you're having exactly?

Maschine MK3 won't supply phantom power, so the SM7dB is effectively the same as a SM7B. Make sure you have the preamp switch set to "bypass". It might be that the MK3 preamp doesn't have enough gain as the SM7B signal level is really low.

A notoriously low signal Mic combined with a standalone with a notoriously low Input Gain and no PP might be a combination from hell.

Get one of those 30$ phantom power boxes to be able to enable the pre-amp ?

Thank you ! I thought so too , but while reading the information on the N.I. site then I couldn't spot the exact place where it said that the KA 1 had Phantom Power so I thought better not suggest KA 1 if not certain !

Yeah , maybe you are right , and the Behringer PS400 referred to by you probably is of a really nice quality. With respect to the KA Audio Interfaces , then I haven't bothered to connect mine yet as I do not have all that I need yet to use as I want , so I don't have the possibility to test , but it is possible that you can power the KA Audio interface from an USB PSU and then use the in and out without it actually being connected to a computer ? I mean I dunno. Personally I like the idea of the Audio Interface because it's a versatile interface. But I also like the idea of the Behringer suggested by you 🙂

P.S.

I found a rather negative review of the Behringer PS400 over at Thomann , With these highlights , quote (have never used such a device so I have no idea about the validity of the claims , so just sharing !) :

- Output voltage (unloaded) equals 12V in 12V-mode, but only 31V in 48V-mode, i.e. much too low! A short check of the internal electronic circuits shows a multi-diode trippler, thus limiting the output to 3x the input voltage, i.e. 36V max. It never will/can reach 48V, as claimed!

- The output voltage STRONGLY depends on microphone current drawing! E.g. in 12V-mode the voltage drops from its unloaded 12.0V to 10.4V (at 5 mA) and 8.5V (at 10mA).

But much more serious in 48V-mode: from 31V (unl.) to 22V (at 0.7 mA) and 12.5V (at 2 mA)! Note that common microphones typ. require 2-5 mA at 48V!

Fazit: at "48V" setting the unit can not be used. Likely many people will be affected by this deficit, without knowing.

It's a fair question... But at that point, you might aswell just use one of those interfaces as an external interface for the M+ instead of doing all that interface connected to another interface inception; the interface would need to be connected via USB to the M+ anyway so to use that + audio cables makes no sense... It's redundant.

What the heck? But on the M+ do you have the KA6 selected as the interface or are you using the M+ internal interface?
