Pedal Pal Stereo Expression CV Question
Hi everyone,
Just put together a Pedal Pal Stereo. Everything is working as expected, but I am having some issues with the expression pedal connectivity.
I am trying to interface w the expression pedal input on a Meris Mercury X. I checked… exp i/o operates on 0-3.3v and delvers voltage to the ring of the TRS cable. I have a V1 board and all 3 jumpers are in the right place (mine pcb came with a sticker to account for the silkscreen mislabeling).
This is what’s happening:
When I plugin a TRS cable from the expression jack of the pedal it illuminates the CV LED lights when the exp pot is turned cw. When I adjust the exp pot there is no change except at the lower end (ccw) of the dial when the LED dims and pedal responds suddenly. I’ve scaled the expression input in the pedal too…
Dear Stefan, Thank you for your prompt and through reply. Switchign the jumpers did the trick. It appears that the original silkscreen label was correct? Long time time DIYer, but first time pedal user.....I still learing all of the ins and outs. At any rate, Everything now works flawlessly, sounds great. A solid addition to my kit. Thanks again!
