That's simply untrue, The product itself is solid. I've deployed them for people in complex settings and they work without issue. There's nothing unusual about northern New Jersey, but shallow user knowledge in an ever increasingly crowded RF space presents a number of challenges for people working at the DJ and casual music level.
Mix:
The reason your mic didn't work in one instance and then worked fine in another likely owes to simple human error. Simple mistakes we can make when we're in a rush, or miss a detail in the manual. The two most common are:
- turning off the first transmitter before completing a scan for the second mic.
- having live transmitters in close proximity to each other while running a scan (this includes ANY transmitter, not just the BLX mics.)
The first mistake is easy to make (even repeatedly) in the haste of getting ready for a gig, Despite the display showing two discreet frequencies for each mic the second result may overlap a harmonic of the first - cancelling out just one mic.
Everything can look correct on the displays (2 discreet assignments) but the scan feature must resolve for BOTH an available chanel AND compatibility of the associated harmonics. That doesn't properly occur if we inadvertantly make a mistake as listed above.
