Hi im sorry if this sounds a little dumb!!! last weekend while i was on a gig i tried to hook up my lap top to my mackie mixer (cfx12) but i wasnt able to get winamp to play through it, which channels should i be using??Many thanks zoe

With a stereo splitter cable that takes the stereo 1/8 plug of the computer into two RCA plugs you could go into the "Tape Input" of the mixer... OR take a 1/8 stereo splitter cable from the PC splitting to a pair of 1/4 inch plugs go into one of the 4 stereo input pairs on the mixer... like 7 and 8 or 9 and 10 for example.
