MC-700 subwoofer

[javraham]

Hi,

I just got my MC-700 yesterday and it sounds fantastic out of the box. However, my 2 subs have a loud hum now. They have always had a very low hum (MFW-15's) but it is much louder now. Any advice on this? I am going to hook up my old Integra again just to verify the amps in them did not coincidentally go bad.

My guess is an earth loop, try a power cords without earth connections for the sub woofers.

Cheers
Gary

Thanks! I was able to greatly reduce the noise to acceptable levels.
