your probably going to want to do moare than just wire a lead to it and put a potentiometer on it. You probably want to think about getting the impedance right for an input. Also a decoupling capacitor or transformer can help too. IMHO that wiring an input stright to the chip that was never meant to see an outside elctricl signal might just end up damaging the chip from plugging and unplugging the cable to other devices.

this is about adding a input to the poly800

I just was hoping someone would bounce some info back to me.  how is
an IC numbered. i have uploaded a picture of IC1 named NMJ2069.jpg
with how i think its numbered. if someone could tell me if i was
right or wrong. that would be great.  just kinda wanted some
feedback before i started cutting wires.  anyway...i was also
thinking for the input i would need to put in a pot to limit signal
coming in. any ideas?
