Thanx Jond...I talked to the dealer and he said some transformers are more susceptible to minor voltage differences (117VAC, 120VAC) of the power outlet (or the quality of the power) in differentt areas..hence they can be quiet in some systems and buzz in some other. The thing is my neighborhood is pretty new (2, 3 yrs old) so i dont think the powerline here is that bad. I did ask for an exchange (I only had the Air Tight home for one night) ..he gladly agrees but i have to wait for 4-6weeks :( Hopefully the new one is ok . Wish me luck !
Air Tight ATM-2 mechanical hum.
My new Air Tight ATM-2 emits an audible hum (which can be heard from 3-4ft away, music off) from its power transformer. Although the output at the speaker is fine, i'm curious if this indicates any defect (cuz i expect a dead quiet unit in this $9,000+ price range). Anyone has any input? I'd appreciate your contribution.
Thank you.
Thank you.
