Why are there two Firewire ports?
Firewire allows you to chain various devices together. You can use either port to
connect to your computer. External hard drives or other Firewire devices can be
connected to the other port.
Does the MultiMix computer connection operate at FW400 or FW800 speed?
The MultiMix uses the IEEE1394a (400Mbit/s) protocol. This is the "original"
Firewire protocol, not the newer IEEE1394b (800Mbit/s) standard.
I'm getting hum or a digital glitch noise through my mixer when it's
connected to my computer. Help!
Try using a ground lift adapter on your computer's AC plug (one of those gray
adapters with three holes on one side [for your AC plug] and only two blades on
the other side [to stick into the wall]). This should solve your problem.
