We always advise against running two different brands of 2.4GHz wireless DMX at the same time in the same RF band.
If you must run two separate systems, we recommend using 900MHz RC4 equipment, which is far away from anything in the congested 2.4GHz band. Alternatively, if you are just using a few units from another brand, substitute additional RC4Magic rental units for guaranteed peace-of-mind and functionality.
This is why Disney, Cirque du Soleil, Blue Man Group, and many others use RC4 exclusively for wireless DMX. Not to mention, our prices are comparable to those of our competitors!
