Audio connection quad amp to pc
« on: November 28, 2018, 01:08:44 pm »
Hello,

I recently bought a San Francisco rush atari racing cabinet and am looking how to convert it to a multi game cabinet.

But,now I am unsure how to connect the atari SF rush quad amp to a pc for conversion.

In the wiring manual I see a connector labeled chin2 with connector pins for frontleft+ -, frontright +-, backleft +- and backright +-
But how would I go from the pc side to these 8 pins?

I could also omit the Atari amp and only use the wires going to the speakers, but which amp would I need to use to go from 4 speakers+sub to a pc soundcard?

Thanks for any tips.

Mhm... The most easy solution seems to be setting your soundcard to 4.0 Sound, and then just use two 3.5mm headphone to 2 rca cables - that would give you the 8 required lines.


+ being the individual signal, - being the common ground
I do all that stuff even without a Joystick ;)

Thank you for your answer!

I understand that the 2x 3.5mm to 2 rca cables would give me the 4 + ones (FL FR RR RL speakers).
But how would I connect (or from where do I get) the 4 common ground wires?

An RCA jack has two Connections - just connect the outer one (the ground) to each - input.
