Re: Stereo floor monitor for vocalists?
The most wedges I have run for a single person was 5- on 3 different mixes plus stereo sidefills.
They were arranged in a U with a single wedge downstage-with just his vocals. Then a pair of wedges a bit up stage with the backup vocals. Then a little bit more upstage was a band mix with the "important" instruments. The side fills were pretty much a full band mix.
This way he could step in and out of "various sounds" as he wanted/needed.
The stage volume was well behaved-a good FOH guy and a talented band that played good music. The end result was pleasing for everybody-including the audience.
The whole "trick" to getting a good sound is BALANCE. And EVERYBODY has to be a part of the solution. As soon as one person gets "out of control", the whole thing starts to fall apart.
