Please forgive me if this redundant or even in the wrong subforum. But does anyone have any experience playing an 18v bass with the Behringer P16s ? If so, please let me know how well this is working or not working. My music director is pushing to get these for our church. I haven't had any experience with these personal mixers and my MTD is 18v. So, I need to know before I sign off on purchasing this system. Thanks!
