Our only assurance is our reputation to create the best possible product that is now available to every performer, audio mixer and technician. They can upgrade when they are ready. New young acts have been very easy with the right setup. Veteran acts, when they are ready to try IEM, have been fairly tame. Veterans also usually need a little more time to adjust.
Lead singers tend to jump right into it when they have a good mix.
If everyone on the stage is on IEM, you can really eat up a lot of mixes on the monitor console. It is a lot of stereo mixes. Some console companies have done a great job keeping up and others are working toward digital. Unfortunately, many groups currently have to decide who gets stereo, who gets mono, effects - and you still run out of channels. Future Sonics likes to work with engineers to figure out the best approach for the situation.
