Roku 3 and old school receiver

Help! The Roku 3 does not have a separate audio connection, and my old school Technics receiver doesn't have HDMI or optical digital connections (just RCA). So, I need to use an audio extractor/converter in order to get stereo sound thru my receivr. The only connection that is still available on the receiver is the Phono. Can I use this to connect to the extractor so that I can get stereo sound for the Roku?

You can use this input switcher from Schiit Audio that will allow you to hook up 2 sources to one input on your receiver. You cannot use the phono input on your receiver if the receiver has a built in phono preamp

Thanks much for the information about the switch. That will solve my problem....and I'll leave the Phono input alone!
