Hi together.
I own a pair of ATC SCM 45 Pro Speakers.
the input sensitivity of the speakers amp, can be adjusted from 1V to 2V.
The speakers are connected to an Interface (UA Apollo 16) with Output of 20dBU.
Volume control is analog, passiv.
Changing the setting at the ATC from 1V /2.2dB to 2V / 8.2dBu makes a not subtle change in sound.
I did some research, but did not find a clear answer so I want to try it in this forum.
With the 1V setting the bass sounds "mellow" and everthing else is somehow undefinied. But the bass is more prominent.
With the 2V setting everything comes to live, bass is less prominent audible, the whole thing sounds more cohesive.
And I really do not mean subtle changes. The intern, customers and even my wife can hear a clear difference.
I measured the frequency response at the listening position.
The curve is the same with both settings.
What is happening here? Is the phase differnt, is it a differnt level of distortion?
I would be really intersted in what is going on here on the technical side.
I say thank you in advance to everybody!
