I have a Mini and two Flex'es. This weekend, I'm renting a studio for a shoot, and they have one set of Plus II. Since they have 4 of AB1600, I'd like to use them all by mixing my Flex'es with Plus II. I've never used Plus II transceivers, but according to the manual, there are 4 channels. The Mini and Flex have only two channels. Will it work if I set everything to Channel 1?
