Low volume from one channel w/AT-LP120-USB
I recently purchased a new AT-LP120-USB and have been having a somewhat unusual problem. In using it for the past few months, I notice that every so often, after first turning the unit on, the right channel plays at a considerably lower volume than does the left. The only fix for the problem that I have discovered to this point is unplugging both channel cables from the back of my receiver and then plugging them back in - both channels will then be playing at the correct volume. The problem described above occurs whether using the AT-LP120-USB with my receiver's Phono input or using any other input (with the AT-LP120-USB's built-in preamp turned on). This problem does not occur with any other device connected to my receiver, only the AT-LP120-USB. And so you are aware, once I've unplugged the AT-LP120-USB's stereo cables and plugged them back in, the volume levels remain fine. The problem only seems to happen when the turntable is switched off and back on again at some later time.
My AT-LP120-USB is still under warranty but I'd prefer not to have to ship it back to you for repairs unless I absolutely have to. Any help will be appreciated.
