This unit is amazing as long as you are using a firewire based computer, but both Behringer and Mackie units have the option of RTA over the wireless network, and i can't get it to work not even on the iMac with a cat5 cable into the computer, this is the only thing making this perfect machine useless (limited to a 6 foot max FIREWIRE cable to use RTA feature for live sound monitor mixes
