Where does the S-Video cable plug in to my PSX?
The Multi-A/V Output on the back of the Playstation. BTW I recommend NOT using the two Audio jacks from the “integrated” S-Video cable. Instead, take your old composite cable, ONLY plug in the two Audio cables (yellow and red) into the old Composite Audio Out ports on the PSX, and then hook it up to the Audio Input jacks in the back of your T.V. Sort of like using the integrated S-Video cable only for video and the composite cable only for audio. Makes a minor improvement in audio quality, because it’s not all packed into one cable at the beginning.
