Hi,

So, I went back to the room and there was a Phillips OccuSwitch Classic motion detector mounted on the ceiling. I downloaded the manual and opened it up. I turned off the ultrasonic detection, and presto – the AF levels immediately dropped to 0 on my xmitter! As soon as I re-enabled the ultrasonic motion detection on the Phillips unit the AF peaked once again. Problem solved!

Thanks you for the suggestions.

Hi,

Good thought, but it’s a small 12x 12 meeting room – no tech built in. Low to no chance of other wireless mics in the area.

Hi,

Yes, there is a motion detector in the room that controls the lights. I know very little about motion sensor tech, could you explain how would this cause AF level peaking?
