Seeing if anyone has had this issue with the Lectrosonics UM400a BLK 26 in IFB mode. The issue encountered is, after about 10 min of good strong audio sending to multiple R1a units on set. The audio just fades away, comes back and then fade away. Here are all the things tried and observed to solve the issue. When I send it back to Lectrosonics how should I describe it? So I don't get a message back "We can't find anything wrong." because it looks and acts fine at first, but it seems to take a few minutes for it to happen. Thanks Observations: 1. Still solid green power light on UM400a 2. Green modulation on audio lights on UM400a 3. 3 other identical setup bag rigs with own IFB UM400a on other frequencies (swapped with others for testing) same result with bad unit 4. Sound Devices 664 x1 out put is used on all bags (swapped with others for testing) same result 5. Ta3 -Ta5 cables (swapped with others for testing) same result 6. Uses 9v eliminator (swapped with others for testing) same result 7. IFB is five frequency blocks away from nearest other Lectros on set and changed multiple times to clear channels and checked with other bags IFB to not be intermod. 8. Power cycle unit for 30 sec. fixes issue for about 10 minutes 9. Running just one bag or all bags with IFBs and same result with bad unit
