I'm not sure if this is the right forum, but since has helped me here is always very good, trying it a try ;-)
It's all about audio. I connected an old Sennheiser MD421N (via cable selbstgelötetem) s.den Mixer Yamaha MG 102nd The signal from the Micro is so quiet that I have to gain levels and fully turn on (at 3 / 4 Master) to get a normal signal. From here there is a sound unbearable (over speakers and headphones s.dem mixer).
Specifically, it is rushing to a certain point, a relatively quiet, but when it exceeds a certain gain - or again louder level value by one step.
I s.habe the phantom power (the same goes for all channels) would actually make any difference?
Now I wonder if there a preamp helps. But that is normal that you want to be in front of a blender again a preamp? My choice would be the ART Tube MP, but I am open to other suggestions synonymous (in similar price range).
Antwort von hofnarr:
the micro-amp is mixers in the small yamaha in this price class is not actually the worst, the output level of a MD421 is rather weak. 60db gain are synonymous because not enough sometimes. with gain control to stop and open channel fader start some more expensive consoles synonymous with noise clearly audible.
selbstgelötete of the cable to xlr kleintuchel is wired correctly?
incorrect pin assignment is the signal from the micro may only "one leg" and therefore you lose before the first gain stage some db ...
here to the correct safety circuit:
xlr pin 1 ---> din pin 2 (ground) XLR Pin 2 ---> din pin 1 (+ / "hot") XLR Pin 3 ---> din pin 3 (- / "cold")
if present, phantom power would have to ignore the MD421 really brave. tentatively expected to switch off for clarity.
an external, higher-quality preamp should help. the art tube mp, I do not know, MD421 and MD441 I have already easily operated in combination with spl track one, Focusrite ISA One and sound devices mm-1. But the three were equipped with input transformers, this maximum gain was never really necessary.
