Good morning! (at least it's morning where I am!),

I currently have one AVX-ME2 that I plug directly into my camera XLR.

Possibly a bit of a daft question, but can you use more than one of these at the same time without interference? In the future I would like to acquire a couple more to mic up two other members of the wedding party, so that I have the father of bride, groom and best man mic'd up. I'd just plug them straight into a Zoom H6.

Thanks!

Nathan

The answer will be yes, but the other systems will need to operate on different frequencies or channels whatever they may call them.

That's what I thought, thanks Brian.

Frequency will be the same. Every unit uses a different channel. If i'm not mistaken you can use a set of 8 in one location.

Yes, 1.9GHz I believe! Useful to know. I doubt I'd ever need eight!

Yes, with multiple transmitter/receiver systems You could not use two or more transmitters with one (1) receiver.. or two or more receivers with a single transmitter.
(the latter is possible though with the standard UHF systems.. the Sennheiser G2/3 for instance.
