Line out pins on top layer PCB

I want to feed the stereo OUT to a builtin amplifier (custom box), but I still want to use the 1/4 audio barrel connector for sending the same signal to a mixer. I tried soldering directly on the pins (top layer of PCB), but I have no signal! Any information, what alternative do I have?


Hey, is anything connected to the output port jack? If nothing is inserted, then the signal pins are shorted to ground by the jack construction itself.

Right! Will simply insert an 1/4 to 1/8 adaptor…
