MP573 Microphone preamplifier / Re: No Input

« on: February 01, 2023, 05:19:58 PM »

Jean Pierre,

I am trying to test in the next way, but probably wrong:

I use Reaper and I insert the preamp in a track with "Reainsert". The problem is there is no return signal. (with other modules everything is OK). By the way, DI doesn't work either.

I put some pics:

With a MIDAS Compressor:
 


With the MP573

I don't mean to interfere, but since I use Reaper (and Reainsert), I thought I would comment. Your hardware return looks incorrect. Your hardware return should be the analog Return on your interface. For instance, mine is Analog 1 using the Audient ID22. However, I know you can name these whatever you want, and maybe you just have a different naming structure. Hope this is helpful, and if not, please ignore. Best of luck

Thank you for the great customer service. The screws arrived yesterday, and I completed my build this morning. So far the DI and the phantom power with a mic all work well. I will test the line in option soon, but I have confidence it will work like everything else. Can't wait to use this in my next recording session!

Hi JPK,

Here's another question for you. 

I'm on step 29 attaching the PCB to the front panel. The front panel lines up beautifully, but none of the screws I have left (pic) fit through the designated holes of the metal front panel. I removed the front panel, and, alas, none of the screws fit in the spacers either. 

So it seems like I am in need of 3 black countersunk screws that are small enough to fit through the metal front panel and into the spacers.  I've confirmed that I did not use the incorrect screws earlier in the build.

Thanks,
LKL

Thanks for clarifying!
The kit has been a joy to put together so far.

AB528 Microphone preamplifier / AB528 question

Hello,
I'm on step 20 Transformer T2 mount and I'm unclear about the spacers. The parts guide says there are (2) M2 5x3 spacers. Looking at the diagram, this looks like the part (photos) but there are five of them total. 
The instructions seem to imply that I use two spacers on each screw, which would mean the parts count should be 4 (and I received an extra spacer). I don't see where elsewhere in the build it calls for a spacer like this.

If you could clarify I'd appreciate it. Thanks!
