Yes you can! This is the sends on faders function. To the left
hand side of the
screen are 16 keys representing each of the 16 busses available in the
console. If you double click one of these, the whole bank of faders below change into the
channel sends to this buss. So, for example, you have a
monitor mix on aux 1 and you need to turn up the vocal in it, you would double click the "mix 1" key, and the faders will move to represent the
send levels from each
channel to that mix. Its then a case of pushing up the
channel fader for the vocal. Then press the same mix key again and the surface returns to the "normal" mode of mixing channels to the stereo buss.
After reading through your question again, just to clarify, this is a global change, and from the time I had on it, i dont think that it is possible to swap individual faders to control different mixes simultaneously. However, I think that the complete bank swap makes it easy to see what is going where at what
level, and is also a fast way of setting up
monitor and effects mixes. Theres a couple of other things related to this that I didnt get the chance to test fully but which are of interest. Firstly, how the
console handles stereo mixes; do you have to set one side at a time on the faders or do the faders control
level and pan is set somewhere else?! Secondly, whether the LS9 follows the same as the other
yamaha digital consoles, where selecting an aux also assigns it to the solo bus, which makes
monitor mixing super fast.
There is also the option of several layers in the LS9 (1-32, 33-64, master and custom). The master layer has all the output master
level controls
in one place, and as default, the 32 mic pres are patched to 1-32. You could however, also patch them to 33-64, and use the second layer as the sends to monitors with different eq and comps. The custom layer can apparently hold any combination of input and output functions but this was a function i didnt get to try out.
Hope that is of some help
