Hello folks,
Long time I haven't posted there.
I'm stuck in my search for a norm concerning balanced line gains. I remember having seen schematics where the driver is simply reversing one line (leading to a gain of 6dB), some receivers are dividing by two, some receiver are simply making the difference (leaving any gain as is)... It is fine when you go through a device, because as long as the input and output have the same topology, they are transparent gainwise.
The case of microphones is different. The sensitivity is given in dBV (from the factory calibration) but I cannot figure out if this tension is meant to be the difference between the lines or the single ended signal.
