I am involved in a band with six members, one of which plays several instruments. In an effort to improve our chances of getting a good sound check by relieving the FOH sound engineer of the monitor mix burden, we have decided to move the monitor mix (and in some cases, the main mix) to the stage.
After giving Mr. Several Instruments his own portable mixer, we are now down to eight signals. We intend to provide the FOH engineer with either our eight signals, or a two-channel main mix out. The mixer we have chosen for this purpose is a Mackie 1642VLZ4 (user guide), which will provide four monitor mix sends, eight balanced line-level direct outs, and two main outs. This Hosa snake will convert the eight direct outs into the usual male XLR connectors that the FOH engineer expects.
My concerns are:
Mixing engineers usually expect mic level inputs. Are the line-level direct outs generally compatible with the FOH mixer's mic inputs? Yes, I know about DI boxes and the like, but can I expect everyone to have the usual 20db pads and gain controls in their desk, and know how to use them?
How well will the typical FOH sound engineer adapt to this arrangement? Are they likely to be receptive to this arrangement, or will they balk?
Have I overlooked anything?
Note that this is a small (by economic standards) band; we won't have Tom Lord Alge mixing for us (quite the contrary, if you get my meaning).
