cgs tube vca (cgs65) - audio/cv SN?

hello...
what do the audio and cv SN inputs on the pcb actually do?
thanks!

Hi Michael.
They are simply points to add more inputs. For an extra CV input for
example, just connect a 100K resistor to the CV SN. The other end goes
to a new CV input socket.
the CGS65 is a wee bit short on CV inputs - I wanted 2 on mine, so used
the CV SN to connect the pot to.
(just finished adding the last few bits on mine - am about to test it,
when I've let it sit for a while. there's nothing like a fresh look at
it in the morning :-)
cheers,
Dave

Do you need to do anything special to hookup a audio signal to the "audio sn"? i.e. can I just hookup the wire directly to the input or should I connect a resistor first? If so, what value resistor?
What does "SN" stand for anyway?
Thanks,
Jim

Hi Jim,
"SN" stands for summing node. You can add extra inputs here by
connecting them through 100k resistors. Take a look at the schematic
again and it should present itself. Use a 100k resistor for each
extra input, and do not connect directly here without the resistor(s.)
Great module.
Regards,
Michael Ford

Thanks for the info!
I've got 4 ready to be wired up! Can't wait to get them done!

Hey,
Thanks to everyone for answering those questions. I just got back from
my (belated) honeymoon.
So...
Yeah, what they said : )
Happy building!
