Just purchased an S1 Pro to use as a stage monitor for my L1 Pro 16 (I know, I shouldn’t need it 🙂 ). Tried to connect with an XLR (male) from the Pro 16 Line Out to Channel 1 of S1 Pro via XLR (female). I turn everything on and up and the L1 Pro 16 sounds great as usual, but “crickets” out of the S1 Pro. No sound. Any guidance/ advice from the group? Should I be using a 1/4” TRS into the S1 Pro?? Any help is sincerely appreciated.
