Fbq2496....how loud is your hum?


hellu!
ok just bought this fbq2496..
and have been about the hum issues....
how loud is the hum, if someone still have that issue?..is it clearly heard ?
i have a very low humming noise coming out from sub...when i really listen after hum...
and now that i know that the hum is there it annoys me..
i already tried to shift power from an grounded outlet vs a non-grounded one..no difference...

but when i pull the rca coming from receiver..the hum is gone...
have any of you tried or/ whould something like this be helpful:

Re: Fbq2496....how loud is your hum?


So you have RCA out at the receiver and XLR in at the BFD. Can you tell us the configuration of the cable you're using?

No hum with my FBQ2496, and I am using RCA cables only.

I would remove the pin-1 to pin-3 bridge, leaving pin-1 open.

Yep, I'm using 1/4" to RCA adapters in the jacks on the FBQ.
