Here's a question that's been on my mind: I have a Joytech AV control center 2 switchbox. So far I've connected all my consoles to it via RGB scart and then onto my PVM with BNC-scart adapter.
But now I'm getting more consoles and I was wondering what to do. I play a bit less nowadays on the PS1, so I was thinking if I could get something like a PS1 S-Video cable and hook it either in the front (one more extra connection with S-Video and composite, backside has 5xRGB scarts - but these also have S-Video and Composite) or on one of the same inputs than RGB scart. Now, I tried this setup with a PS1 composite cable, but I just couldn't get a picture from either connection setups. Cable is not faulty since I already tried it directly to a PVM.
My PVM takes S-Video, but my issue here is that the BNC scart allows me to hook the audio directly to my amplifier and get a 5.1 stereo sound for my consoles. Putting a PS1 into the PVM is a possibility but then I'd have to settle for mono audio from its dinky speaker.
So I guess what I'm asking is - why doesn't the composite cable give a picture via the Joytech switchbox? If I use an official PS1 S-Video cable, would it be different and I could get the picture and sound using the switchbox?
You can't send Composite or S-video into the switch and out to the PVM if the connection at the end is RGB. Input and Output signals in the chain must match.
Get the 3 RCA Composite cable for your switch's output: yellow to the PVM, red and white to the amp. Or same idea for an S-video + 2 RCA audio cable. If the audio inputs in your amp are already occupied (by the Scart-BNC cable), get a
passive audio mixer so you can have multiple audio inputs going into your stereo setup.
As an aside, I noticed the Composite, S-Video and RGB are on the same input but I'm assuming that they don't interfere with each other and you can have 15 consoles connected at once without a problem (5 for each connection type). Let's say you had NES Composite, N64 S-video and Genesis RGB on Input 1, and matching outputs to your PVM, would the switch keep separate clean signals with all three consoles turned on? My gut says yes and this is probably an obvious thing if your switch isn't junk. PVMs can definitely have these three different inputs directly connected and on at the same time, using the front panel buttons or OSD (depending on the model) to switch between the three inputs.
If you want more RGB inputs, the answer is really to daisy-chain a second switch or get a switch with more inputs!
