I installed 2 pair of R-51PM's in a small hall and connected the balanced out from a Mackie unpowered mixer , converted XLR to RCA and plugged Left out of mixer into Left in Phono (switched to line in) and Right out of mixer to Right in Phono to second powered speaker. Definately have audio out from mixer but no sound in speakers. Tried switching inputs via remote, on/off, etc. Any suggestions? Do both phono inputs need connection on each speaker to work?
