Topic: BF Pro started making loud zap noise on AN 1+2 on power down...

oh no!

3+4 are fine.
even when dimmed, zeroed etc it zaps right at the last moment of power down.

what to do?
what could it be?

Try a different power supply. If you don't use one - did your USB port change?

Is that new or was like that from the beginning?

it had been running beautifully for 3 years and 5 months.
last performance 2 people briefly noticed a burning smell. all the kit continued working fine so i thought nothing off it. the BF was shut down only after the pa was disconnected.
so when first back in the studio and i put the laptop in sleep i noticed it.

In that case service should have a look inside...

sorry to take up more of your time...

i should send back to Thomann even though it is outside of their 3 year warranty?
is that because you like all servicing requests to come via the dealer?

In that case, you could contact Synthax UK and see what they say...

a ballpark quote from Synthax of £150-200 is just too much to fix such a problem.
i can use the device for its other features and put the money towards another interface.
