Identification for onboard switch needed (Receiver Pioneer A-331)
"Leif Neland"
Phil Allison har bragt dette til os:
DJ mixers have a "cross-fader " that allows a pair of stereo channels to
be mixed in any proportion. Most DJs work the ring of the things - so
much so that it is standard practise make the cross-fader a "user
replaceable" module fitted on sub panel that slots into the main panel.
Are anyone using an optical fader, where moving the fader allows more or
less light to a sensor, controlling the fading?
Or should I file a patent claim? :-)
** I built such a set up for a customer in the mid 1980s.
Worked like a charm.
A few high end DJ desks have optical or VCA x-faders.
