Just got a Dr. J Professional projector. Want to use it on my patio, which already has decent Infinity speakers wired up for music. They are connected to my older Yamaha theater as the B speaker set (A is installed inside as the surround and wired in serial with another Sony system). Anywhooooo.....simple question for the pros here: How to get the projector sound to those wired B speaker set...projector is not BT, nor is the Yamaha. Would a BT tx on the projector and a paired BT rx in an open input work or would the latency be a problem? Any suggestions would be appreciated! Thanks!
