Build help and troubleshooting => MP573 Microphone preamplifier => Topic started by: morast on March 13, 2026, 02:30:03 PM

Hi,
i just finished building my first of 2 MP573 - everything worked fine & sounds great. However, i only afterwards noticed, that the grey output level knob is placed before the output transformer (which is explained in a blogpost on soundskulptor website) and i can not fully drive the output stage and attenuate signal after (like i think it's possible on my MP512s) without overloading my RME line-ins.
Due to lack of space in my lunchbox i cannot use a PAD500 module - is it possible to just plug in a switchable inline attenuator like the Shure A15AS or the AT8082 which have around 1kOhm impedance according to specs, to get a similar attenuation without change in sound?
(My RME line-ins that come afterwards have 10kOhm input-impedance).
Thanks for you infos & cheers from Austria,
Herbert
