I have a pair of CDJ400's and DM1050 plugged into an Edirol UA1-EX interface (which is hooked up to my computer). The signal then goes from the interface to speakers.
When I am DJing with the above mentioned system, I occasionaly get a very lound 'Pop' and the visual display lights jump to full for a second. I've also noticed that when unplugging the equipment(the phono connections, and even the USB connection to the Computer) a shocking sensation when touching the metal of the connector. It must be pointed out the all sequipment was off when i was doing so.
Is it possible that there is some kind of electrical build up somewhere? Is this a common problem, or is it likely to be a faulty peice of kit?
Any help with regards to this matter would be much appreciated.
