I have just bought an old Wavemaster 3085 5.1 Surround-Sound System. The only input to this device is a 9 pin DIN male connector and I need this cable to connect to my DVD player which has 6 RCA connectors. 2RCA connectors go to the subwoofer, 2RCAs go to the audio and 1RCA to the video connector on my DVD player. Can anyone help me identify the pin outs from a 9 pin mini din and how to connect the pins to the RCA connectors?
