MP573 Microphone preamplifier / Re: Calibration

So .. I finally managed to try this fix and it works perfectly.
Very happy my trim knobs on the stereo bus are matched!

One more question: can I do the same with my 5.99 and 5.12?
What resistor do I look for.

Thanks!

Thanks, JPK!
That's a doable fix.
Will try it as soon as I can and post the results..

Thanks!
At +10 the output is nearly identical.
At -10 there is about 1db of difference.
What values should I try? Is there a way to measure/calculate this?

Hi there,

Sending the mixbus through MP573s lately, I noticed the output volume of my two units is different.
Using a mono signal, ProTools meters and Waves PAZ analyzer, I have to set the trim knobs in a different position to get a centered image.
Not a big issue, but it would be nice to match the preamps.
Is there a way to do this?

Thanks,
Bert
