Evening all, I do hope this is the right place to post this
I have a Denon MCX8000 and the crossfader needs replacing, however I’d like to do away with it altogether and replace it with buttons that mute momentarily when pressed
Trouble is I have no idea how to achieve this and thus i’m looking for advice/help. I did take the fader out to inspect it and noticed it only has three wires attached so in theory it’d be a ground and A and B?
Closing the ground to either A or B would work? or would I need a resistor too? or am I completely wrong?
Thank you for reading
Best
Tony
Hi Tony,
Not exactly the right place, here we talk about DIY MIDI Devices
There’s no service manual/schematics available for this product, but.
Denon DJ Replacement Crossfader for MCX8000/MC4000
As you can see, pinout of the connector CN1 is GND, ADC, VCC.
Means that pot drives an ADC(Analog to Digital Converter) with a ADC value range of GND to VCC
then ADC pin value range is ADC=GND (only channel A) to ADC=VCC (only channel B),
where center value is ADC=VDD/2 (both channels A and B mixed equally).
Both channels muted at the same time is not possible, using this ADC input.
Still possible to replace the fader, it’s cheap 
Best regards
Hey Antichambre, thank you for the reply
I’d really like to replace the fader for buttons if possible. From what you have sais there if i was to connect a momentary on switch to ADC and GND pressing that would mute channel B ?
Regards and apologies for posting in the wrong place
Ok

Thank you so much Antichambre
