I just bought one of these to use in my living room, and I need to find a longer power cord for the receiver. I think it's a DC plug, but I don't know for sure? I need one atleast 8 feet long, and the one they sent me is probably 5 feet at best. The plug unit itself is made by DVE, and it's model number starts with DSAPFA12 if I remember right. Does anyone know where I can track a power source similar to this with a longer cord? Can I just splice in a longer length? I am having a really hard time figuring out what I need.
