  • Quick questiion about DOA external soundcard

    So I just got a Terratec DMX external sound card. Has no on off switch. When I plug it in the lights flash and relays click--same when I unplug it. Also true is when I insert the connector from the PS--about 1/2 way I get the same flicker/relay click. I checked the PS. 12.4 Volts and even found another with the same connector--no joy. I can't seem to get the company to respond, and Ebay merchant is reluctant to take the return. Any ideas what the problem may be?
