Pastyface wiring

[todos]

Hi all,

Just finished building the pastyface PCB and now looking into wiring. As this is my first board, im a bit puzzled. The way it seems to me, I have to connect the 9v battery to the -9v/G on the PCB (where I connect the - of the battery to the -9v and the + of the battery to the G). Is this correct?

Then just to test my PCB, can I connect the input connector to IN and G (how should they be connected on the jack?) and connect the OUT only to the output connector (also, how to connect?).

Most tutorials i find are based on using a power jack as well (im not using one) and are based on using a central ground (instead of ground for power and ground for input/output). Can power ground be connected to input/output ground to?

Thanks in advance for helping me out here!
