Static noise A20

Hello everyone, hope everybody it’s OK.

 

im from Lima, Peru. I use the Bose A20 aviation headset every flight I have, but recently when I turned on the ANR a very loud static noise started to appear in both cups, and the battery consumption is too high. Hope somebody can help me.

 

greetings!

Re: Static noise A20

Hi Sebastian,

Have had similar problems not with the A20 but with some of my older X models. You don't say if it is a 'powered A20' off the Aircraft or a 2 plug 'non-powered' unit. However, it is most likely not going to affect the issue. I will stand corrected by the Bose Engineers but I would most likely suggest it is a Voltage Regulator fault in the Headset Voltage Control or an ANL Fault causing a high current drain and subsequent static noise. I feel sure the Bose Guys will suggest you return it to your nearest Bose Agent so they can take a look at it for repair processing.

If you haven't tried it already, maybe check with another Headset if you can that it's not the Aircraft output or a power supply fault, but I assume you have done that already.

Good luck,

Larry
