I've been using a Akai AP-A100 turntable and receiver for a while now, but decided to upgrade my receiver. I purchased a Pioneer A 10 K, which just arrived, but there is no place for the cable from the turntable to go. The cable has a plug which just fit straight in to the old receiver, but this one has a signal GND, which screws out a bit, as if to wrap wires around it to connect it, just like with the speakers. I have no idea what signal GND means, but I'm guessing i need to strip the plug bit off the cable from the record player, and wrap the bare wires around the signal GND? I thought best to ask before doing it and finding out i wasnt meant to!
