Atomic Wedges humm?

[mgavin]

Hey anyone who has an atomic active cab or wedge do you hear a small humm or buzz when you turn the amp on? i notice it goes away when the tweeter is all the way off but when i put it half way i notice a small hum or buzz, i don't remember hearing this when i first powered on my atomic and it's not that prominent like a ground loop buzz.... any input would be great, thanks. -mg

mine doesnt have a hum but i do notice like a crackling/white noise type of sound when i first turn it on. it lasts for about 10-15 seconds and then i dont hear it again...not really sure what it is
