Another way is to do what I have done, I have 4 feeds with 1 in stereo, I run all feeds on one PC, an old AMD Athon XP 2100, the Scannercast software for each feed is in there own folders, and the best part, I don't have any Sound cards install into this computer, I run a Tascam FW-1804 audio unit, and it has 8 channels in and 4 channels out via Firewire, It works really well..
