I have no clue why it sounds so different. The Music that hits the amp is now peaking at around - 29 or -30 dBFS - it sounds better.īut this is only 6 dB more of digital gain at the 2V setting + the amp expecting 6 dB more gain at the same time. I switch the input sensitivity to 2V at the active speaker.

The music that hits the amp is peaking at around - 35 dBFS - it sounds not good. The ATC SCM45A Pro is an active 3-way with a 1 dual-suspension Super Tweeter, a 3 soft-dome midrange driver, and two 6.5 short-coil carbon-paper cone. I have the input sensitivity at the active speaker set to 1V. Turning the amp at the active speaker from input senstivity 1V to 2V results in a drop of output level of around 6dB -> at the amp of the speaker.

No one listens tpo active speakers at full level all the time - they blow you ears off. so it does not matter here.įact is, for a comfortable listening (or working level) the signal has to be turned down be around 35 dB before it gets to the active speaker. I can choose to set the audio / music level digital before the converter, or analog after the converter.įor the difference in sound i am hearing by switching from 1V to 2V at the active Speaker, I can do both things, analog gain reduction after converter or digital gain reduction before the converter - the difference in sound is the same. The music is coming from an audio interface. 3 ATC Loudspeakers SCM25A Pro Compact Active 3-Way Monitor - Pair On Sale 8,990. The reality is, as far as I understand it, that the amp sees always less power than it should get on the paper. I do not really understand why one should be a better match than the other. I would be really intersted in what is going on here on the technical side.Ĭlick to expand.thank you for your answer. What is happening here? Is the phase differnt, is it a differnt level of distortion?

I measured the frequency response at the listening position. The intern, customers and even my wife can hear a clear difference. With the 2V setting everything comes to live, bass is less prominent audible, the whole thing sounds more cohesive.Īnd I really do not mean subtle changes.
With the 1V setting the bass sounds "mellow" and everthing else is somehow undefinied. I did some research, but did not find a clear answer so I want to try it in this forum. The speakers are connected to an Interface (UA Apollo 16) with Output of 20dBU.Ĭhanging the setting at the ATC from 1V /2.2dB to 2V / 8.2dBu makes a not subtle change in sound. The input sensitivity of the speakers amp, can be adjusted from 1V to 2V.
