I have recently purchased and setup a SurroundBar SDA IHT.

However the when in use the Sub gives off a high pitch whine. It's not very load but definitely noticeable.

Is this something other users have experienced? Can it be resolved? Or is my unit faulty?

Thanks

Dan

    do you have good cables? might be a ground loop issue or electrical noise from your house wiring, try another outlet.

    Thanks for your replies.

    I tried different cables, and outlets and I had the same issue.

    Being based in the UK I've had to contact the distributer as I cannot contact Polk Direct, they advised me to try reseating, and swapping the Fuse round, which had no effect.

    I’m in the process of getting it swapped out.

    Will let you know what happens
