Not a real basis for design. 'More components can mean more noise or less or the same.Hi all!
I'm a new member of this forum. I was searching for a schematic and I found it here
I play with electronics since I was 14 and since 1988 it have also been my work. I played seriously with audio, but also other linear electronics, digital and RF. In 2015 I discovered Arduino and now the ATmega328p is very often in my projects. My work has been lab servicing on broadcast cameras and video mixers, then HDTV studios design and now A/V infrastructure and main switching systems.
If I would design a mic booster, the specifications would be:
- a very simple device (less components, less noise);
What ???- unbalanced input: it is directly connected to the microphone, then a balanced input is not required;
Doesn't seem to take account of mics requiring a higher input Z for best oerformance, And that is sort of the topic here - apart from the noise issues.- low input impedance (2~3kohms);
- balanced output;
- phantom power;
- gain: about 8dB.
I think the general requirement seems to be for upto 20dB gain ?
