Ya do ‘t need much for a good pair of IEMs. Great for you, boring for someone like me. Do you use audience mics so you’re still able to hear them?
Yeah we still use wedges and mics. All we've done is drastically reduced our stage volume and gotten a better quality sound. Of course, before IEMs, the only thing mic'ed were vocals. Some of these dives bars and restaurants didn't like our noise level
. It also wound up being much less work and setup time.
