New Neumann MA 1 - Automatic Monitor Alignment

- Start date
Hi everyone.
I just updated to version 2.9.7.477, and when I turn on my audio system, KH-80 (permanently connected to the router with ethernet cables and to the audio converter) remain in standby mode. To wake them up, I have to launch the AMA app...
Before the update, all I had to do was turn on my system and they were on and ready to go.
Do I need to make any special settings?
Thanks and good weekend

I'm extremely confused. I MA1 calibrated KH 120 IIs with a Motu M2 interface but now I have no idea how to use my SMSL PO 100 Pro as a playback device with the DSP and other settings such as limiting the volume so I can go above 10 on Windows volume. When I try it does not use them. Am I forced to use the interface for it to work? This is so confusing!

just save your alignment after calibration and change your interface, thats all. You can launch MA1 software at any time to change volume or any saved alignment, no need to connect mic or calibration interface back.

It seems like the volume adjustment I make is not saved when I do this. I end up having to use them at 4% Windows volume with my SMSL digital interface
just launch MA software again and set any volume you want. You dont need to connect measurement interface to do that

I cannot get my speakers to play from spdif without switching to local, but switching to local makes the settings not apply.

Okay never mind I got it fixed now! Turns out I had to use these settings and make a profile with them. I was confused since I thought this was the connectors on my motherboard. I have no idea what they mean by HD Audio output 1 and 2 and when I clicked on play test tone the program crashed every time without fail so I assumed this was for sure not the right device, but doing this worked.

Okay in the end not all is well. Apparently I have to recalibrate because the calibration can only be toggled on when using my analogue interface?? It's not letting me change to spdif so there is no audio coming out. Is there no way to make the alignment apply to a different profile? This software is awful

Since the Neumann MA-1 Automatic Monitor Alignment software has supported stereo subwoofers since version 2.9.3, and succeeding versions have had fixes/improvements for this feature, has anyone here managed to successfully align and bass manage two Neumann subwoofers with it? Is it even worth-it?
I tried, but the second KH750 DSP sub I just got isn't even detected in the set up menu even after much troubleshooting so I couldn't move forward with the alignment. I've already arranged with the seller for a replacement unit since the network input on the sub seems like it isn't working, but now I'm having doubts if having stereo subs would even be worth it at this point. The single sub sounded fine but the null at around 35Hz kind left me with the nagging feeling to fix it.

I was never completely satisfied with just one KH750, and it was only with the second one that the bass could no longer be located.
What causes the zero at 35 Hz? Could you describe your setup and your room?

The the room is 4.25m x 4.3m with hard surfaces all around. Yep, this is usually the kind of room that has bad acoustics but the MA-1 monitor alignment did pretty good job correcting the worst of it for my nearfield listening position.
I considered adding bass traps but I probably need to consult with room acoustic experts first because I don't have much space for those massive things and have no idea where to best install them that's why I've taken the 2nd subwoofer route in the meantime.

The null could be caused by SBIR. At 35 Hz, a zero occurs when the sound reflection travels 4.2 m further than the sound between the subwoofer and the listening position. This could be the case if the rear wall has distance of 2.1m to the listening position. At this distance, it is probably caused by one of the side walls or the rear wall or a sum off all three, if the distance is similar.
Here's a calculator for SBIR. Just enter the distances of the subwoofer.

I don't know if everyone know this but I found a special wiring for the stereo sub to work properly in the system. I don't know if it's specific for the 750 with the 310s, but didn't know until last week and bass lived again.

Hi! Actually, this KB Article is outdated as of today
Last month, I connected my KH120A and two KH750DSPs using the method shown in that link. I noticed that the low-frequency sound pressure felt too high and was making me a bit dizzy. After checking with Neumann, they told me that the graph here is outdated and that the latest MA-1 can properly handle stereo sub integration without using a Y-splitter cable.
