Multiple MR816x

Can I get your input about using multiple MR816x (up to 3 units) in practice?
What are the problems? Advantages? Tricks? Other solutions?

Best regards and thanks in advance,

I’ve used two units together in my studio for four years now.
I love them, the sound quality and the ease of use with Cubase is great……fast and easy workflow under pressure.

BIG DOWNSIDE ….no direct monitoring (zero latency ) with more than one unit.

UPSIDE …This has never been a problem as I can get the latency down to such a short time with these units and drivers that I can track without needing Direct monitoring.

Hope this is helpful.
