Hi Marshallers!
From the first day when we turn on the amplifier there is a brief whistle-like sound that comes briefly through the speakers. What causes this and can you guys tell me how to fix it? It is not too annoying, but in a theatre show with a big PA we need to check the amp is turned on before the show because the noise would be intrusive if we turned it on during the programme.
Many thanks

Hello Stephen,
What amp do you have?
Thanks
