It’s so new that few details were available, but the principle behind it is to avoid the wear-induced problems of traditional graphite or conductive plastic track faders. American Audio have tested it to a million cycles and apparently it still works like new.
As there is no physical contact involved, there’s very little resistance involved, making it very quick and responsive.
I had a play with it, and they’re right – it’s very light; so light, in fact, that a klutz like me could easily knock it out of place, so experts only (and avoid strong winds ;-)
Now for the tech bit:-
It includes two phono inputs, two line, two aux and one mic input.
As well as the optical crossfader, the Q-D5 has balanced outputs and Fader Q start, which works with any of the American Audio professional CD players, allowing DJs to crossfade directly to a pre-programmed cue point on a CD.
There are independent fader curves and a reverse button on each of the channel faders as well as the crossfader itself
