Client has two Kenwood KM-X1000 Amplifier's. Both units have the XS8 System Control green jacks on them. Is there any way to turn these off and on with the 12V jack on the Sonos Ports?
The manual doesn't show anything about voltage but you could also try contact closure with an appropriate cable to see if it turns on.
