mixer
most people find the signal is not hot enough without some sort of pre amp. Lots of inexpensive options out there, do a search here and you will find specifinc brands. Many just use a pre amp, i like the mixer route. I have a 12 channel peavey unity series mixer, i mix drum tracks with that, and run all vocals and other instruments through the mixer to increse the gain, and i get the use of the mixers eq's, which the mr 8 does not have. If your going to a computer anyway, a pre amp may be all you need.
