Mic Setup for Neumann DSP Correction

Hi All,

I fell down the rabbit hole thanks to the excellent information on this site and recently purchased a ADI-2 DAC, and a pair of Neumann KH-80 speakers with their MA-1 microphone for in room correction. It is an awesome setup out of the box but id like to improve it with room correction.

Unfortunately, if i understand the manual, it appears that i cant use the ADI-2 for the room correction as there is no analog input. and i can connect the mic directly to my mac for this purpose. Is this understanding correct?

And if it is correct, could anyone recommend an inexpensive "Audio Interface" (as its called in the manual) to allow me to do room correction?

You should be able to do manual room correction using the 6-band PEQ built into your RME.
Edit: ah, I see the problem. You have an XLR microphone but no way to record it.

That's a DAC and you need an ADC, or more specifically an audio interface with a "pro" microphone input.

and i can connect the mic directly to my mac for this purpose.
No. XLR mics need a balanced connection and they are not interchangeable with "computer mics".

And you can't read the absolute SPL level because the digital level depends on mic sensitivity and preamp gain (unless you calibrate the setup with an SPL meter) but you CAN still measure the in-room frequency response/characteristics.

...A calibrated USB measurement mic is probably cheaper than an interface and the digital level is calibrated to the SPL level.

An interface for XLR mics is about $100 (Scarlett Solo 3rd Gen). There are some really cheap ones as well, like the UMC22 for $50.
Alternatively you can buy a USB measurement microphone like the UMIK-1 for $80. Or spend a bit more on an individually calibrated UMIK-1.

I have the KH80 and KH750 with the MA1 measurement mic.

To use the Neumann room EQ software you can only use the MA1 mic as the software requires you to enter the mics serial number for calibration. (USB mics won’t work). The Neumann room EQ is far more advanced than the 6 PEQs of the adi as it uses more filters plus adjusts for timing / phase differences, which especially for sub integration does wonders without the hassle of eg using MSO.

The MA1 mic requires 48V phantom power and therefore an audio interface which can provide this.

Unless you want to trade in your nice adi2 for an adi2 pro fs, the cheapest solution are the Focusrite interface eg Solo. I use a Focusrite 4i4. They all have reliable drivers Asio and don’t give you trouble.

(BTW. We Neumann customers not only paid premium for an excellently engineered product but also for their also very good customer service. So if you feel you need their expert advice don’t hesitate to contact them too)

Yeah I use a Scarlet 2i2 gen 2 for all my room correction measurements and it rarely misses a beat.

AFAIK the Adi Pro doesn't have 48V, so it will not work. A Focusrite Solo seems to be the cheapest option.

Now I did my homework;-)

The RME

Fireface UCX II​

Has the 48V phantom power, but it’s not cheap.

Again thanks for catching my initial error.

THANKS everyone! All the feedback was tremendously educational and helpful.

I went with the Focusrite Solo and needed cords. Everything should be here tomorrow, just-in time for me to have some fun with it this weekend.
