What I was hoping to do was come out of one of the remote balanced outputs with an XLR > 1/4″ adapter cable into one of the unbalanced inputs on this studio amp, then out of one of the unbalanced outputs of the studio amp to the SM12Vs, with the monitors both connected in series to each other.
The 1/4 input jacks are balanced as shown in your picture #2163
(use a balanced cable as I noted in my other post)
The speaker line from both of the monitor will connect to either the left or right
set of speaker terminals or the 1/4 inch output jack as show in your picture #2164.
(make sure you use the same input channel as the output channel you connect
the speakers to)
