The only way that I know of to engage the six channel analog input is the button on the remote. Fortunately, the 950's remote is tough. (Mine got dropped on the floor and buried in the sofa a lot of times back before I retired it to the "remote drawer" last year, and the remote I replaced it with - an MX500 made by the same people who made the 950's SL9000 remote - has fared equally well in spite of bouncing off hardwood floors on multiple occasions.) And even if something bad does happen, Outlaw will take care of you. They're cool that way.
