Weird loud noice takes over

I have had the same problem--while the unit was plugged in and with batteries in--so no lack of power! I took the batteries out completely--so it is only plugged into the outlet--and it seems to be working fine...for now.

I have had devices in the past that would not work properly when the batteries were low--even though plugged into the wall (so getting plenty of power)--maybe this is one of them. If that is the case (I've only tried this in the past day--so can't brag of long-term success yet!), then I would think that I'd only use batteries when I truly want it to be portable--and make sure they are fresh. Not ideal, but given how much I enjoy the device, is a minor headache.

Hope this works for you or is helpful.

My unit has the same problem, but only when used with batteries. It works just fine wher plugged with the AC/DC converter. I guess it's lack of voltage or milli Amps.

The EQ selected on your iPod doesn't seem to make any difference with this problem. Maybe it's a matter of not enough juice: Alcaline batteries work at 1.5 volts, but NiMh batts work at 1.2 Maybe that difference is enough to create that awful sound.

I had the same problem the loud noise would boom and the volume would automatically lower way down. The only thing I've found that helps is to go into the settings on the ipod and select the bass reducer option. That is the only thing that has helped me and I'm not sure if it's a long term solution.

Hope that helps.
