Sure , lots of odd things can happen. 1. Is the ifb and mixer send coming off the 702? If so is is it line level? 2. What is your routine path to ifb ? 3. Is ifb taking in 2wr com level from 702 and is there a stage announce output ? Or are you using a line dryer to strip 27v 2wr to line level ?

additionally, you watched this yet? kzfaq.info/get/bejne/iNWElshks9iWqIU.html

@@KINETICPROFESSIONALS Thanks for the quick reply! Yes, my IFB had a PGM mix via PGM input on the 702 and IFB was routed from Channel B to headset box. I originally had a line dryer in between the B channel output and the IFB input on the Talent headset box but for some reason couldn’t hear IFB on the headset when the line dryer was in use. If I removed the line dryer and went direct w/ com level power, I heard IFB and the headset mic, but that’s when my director mic went out over program too. I had phantom power going to the headset mic too. And yes, it was line level leaving the mixer to the 702 PGM input. I wasn’t using stage announce. I really just need to sit and test at home and troubleshoot but was just curious if you’ve ever experienced this issue. And yes, that video you linked below is what prompted me to purchase a line dryer about a year ago. I’ll rewatch it tho and see if I’m missing something else… obviously I am. Thanks for your help!!!
