I would have to see a picture...

What you describe should have a stereo TRS jack if that many wires are connected to it. They may have broken into the FX section to use an outboard FX loop. This can affect the overall noise in the synth too. I found out the hard way that running unshielded wires with analog signals around inside a Poly-800 is a great way to reduce the signal to noise ratio. Not good.
