hi ive just got my fast track ultra this morning. i installed it all as said in the start up guide. and it worked fine, connected my monitors and plays through them fine...and same when i connect my headphones i get play back. when i connected my mic to channels 1 or 2 (which are the dual mic and instumnet input) i get signal recording into the computer but mono, channel 1 = right side and channel 2 = left side. when i try connected it up to channels 3 or 4 which are mics only it shows that its picking up the mic and noises, but does not record.. phantom power is on and everything. and i have it all connected up via a usb 2 port (i have a pci card that has 4 usb 2 connections) just wondering if anyone could help me with this? Also i have a really low hum (i guess thats how i would describe it) when i do record...could this be do to bad cables or something else? thanks in advance for any help.
