Aviators,
I started getting a Mic feedback whine during transmission, go read here http://www.vansairforce.com/community/showthread.php?t=150448, then finally traced it to TWO of my Zulu 1 headsets.
In this thread I want to understand if you guys experienced the same with Zulu V1 headsets?
Background:
I have 4 x Zulu V1 headsets: (2 bought in 2008, and 2 bought in 2011)
The 2 bought in 2011 with the newer microphone design, BOTH of them, started giving me serious mic Feedback Whine when I transmit on both my COMM Radios. If I switch OFF the headset ANR the feedback whine disappears. Normal cockpit conversations are fine without the whine. They both effectively are unusable during transmission.
In comparison the 2 bought in 2008 with the older microphone design, BOTH of them are still working 100% fine, if i use them in the same airplane as above, there is no mic feedback whine.
I tried all 4 headsets in a different airplane, and still the 2 from 2011, gives Mic Feedback Whine on Transmit.
So there is definitely a problem with my newer models bought in 2011. Even when i adjust the MIC Gain on the Mic boom to ZERO, i get MIC feedback whine.
