Giant 60-cycle (I think) hum when booting up Defender?

Giant hum that only lasts a second or so when booting up my Defender. Does that point to badness, or is it expected?

Thanks!

Means your amp is working on your sound board. if it's too loud, turn the volume down a bit...
 
It is probably worth replacing the caps on it just to be safe. A hum on startup usually means they are getting weak and letting some AC through untill they can hold enough charge to smooth it out.
