In this video, I show how we use the Behringer P16 Personal In Ear Monitors in our church setup for the band. I love the Behringer infrastructure for churches. We use the Behringer X32 into the S32, into the Powerplay 16, into our P16 in ear mixers. Every member of the band has their own independent mix and there is no need to ask the sound person to adjust monitor mixes.
Back in the day, Aviom systems cost 10X what the Behringer system costs now. I highly recommend the P16 mixers for any band, especially if budget is an issue.
