Can I use a couple of Y cables to split the signal leaving a mixer from the main mix L and R outputs without degradation of the signal ? I'd like to have the main mix and matrix outputs each send a signal to two seperate amps each . Thanks .
If the amplifiers are in the same place I'd recommend splitting right before going in (to the amps' inputs). Simply to reduce headaches, and reduce cable.
Some amplifiers have signal-level inputs and outputs so you can "daisy chain", thus not needing Y-Cables at all.
Not sure what your setup is like but this is an example:
-Patch the outputs from your console into your snake returns
-Signal goes though snake
-Signal goes though cables from snake to where amplifiers are
-Y cables split the signal to two different amplifiers
Or:
-Patch outputs from console to snake returns
-signal goes though snake
-At the other end of the snake a Y-cable splits the signal to go down to different cables, to amplifiers in two different locations.
