Hi All,
I have a Kam KSD2 usb/sd card mixer which has been a wonderful bit of kit. I now have a problem with playback on the usb & sd card channels on the mixer, Both channels start humming during playback. The 2 line in channels from my cdjs work fine during playback. I have change all cables coming from the mixer to the amp and amp to speakers.
Any Ideas?
Thanks apbroncos

Have you got a ground loop isolator?

I'm not familiar with the kit, but if two channels hum, and two don't, I'm incliuined to suspect an internal fault, rather than a ground loop. :confused:

Having re tested the mixer with a ground loop, its still the two sd/usb channels that are faulty (hum). I would agree with you that it would appear to be an internal fault:(. Any body know of a repair shop for Kam equipment please. Thanks
