I don't know if it works or not
And in fact, when I turn up the gain knob high enough, the bars do light up, however they are steady - when there Is sound being played, it (bar) goes up and stays steady till the end of the sound, what I mean by that is when there is a difference in volume, the bars stay in the same position. Should it be that way? I don't think so, but maybe?
I expected them to jump higher when the sound is louder, and drop lower when the sound is quieter. I thought this is a decibel meter, and I thought that's how they(db meters) work.
I also messed up with all buttons and dials on FireOne, but they make no difference. I mean, MIX dial turned to COMPUTER makes a difference, and the PAD button also makes a difference; 'turns off' the bar, but that's how it should be - at least in the 'mix' knob department, don't know about the 'pad' button.
If my explanation is too chaotic, I can provide a video.
