This question is related to the accepted answer to Can the Behringer XR18 XAIR Digital Mixer be used as a breakout box? Please read before offering an answer.
I also want to provide band members with the capability of using the recording XR18 to allow band members to do their own personal monitor mixes on their own personal monitors (earphones). If I use the accepted answer, all of the 8 available outputs on the XR18 will be used for passing instrument signal through to the sound guy's mixer. Behringer's answer is to use a Behringer P16-M Powerplay Personal Headphone Mixer for each member of the band daisy-chained from the XR18 UltraNet port. But the PowerPlays cost US $300 each.
What are the alternatives to using Behringer P16-M Powerplay Personal Headphone Mixers in this use case?
