Title: Multi-Channel USB/Firewire Device
Post by: md on October 27, 2004, 02:55:04 PM

ok, so I'm looking to do some recordings for a band.  Right now we only want to mix in 2 mics with a soundboard feed.  I want a firewire or usb device (i know it needs to be usb 2.0 to handle anything more than 2 channels) that can run 4 or more channels into my computer.  I plan to not record with a delay and just fix the timing in the channels after the fact.  I was looking into the PreSonus Firepod, but there are 2 problems with that device.  For one, it is a bit beyond my price range and secondly it requires XP.  As of now I run win2000 on my laptop and I really can't switch to XP for various reasons.  Does anyone have any suggestions?  I'm preferably looking for a 6-8 channel device, but a 4 channel will also work.

I don't know of any such devices for PC, though I think Digidesign must make a few. I'd say Metric Halo Mobile I/O is the way to go.

according to edirol both the UA-100 and FA-101 are capable of multitrack recording (i asked them because i thought my m-100fx was capable but its not)

I regularly do 4 channels of 24/44.1 with an emagic A62.  I haven't tried 6 channels but it's supposed to work fine (USB 1.0 btw).  With the right software, CPU usage is very low.  Disc activity will also be low as this still isn't much data to write.  I run it with win2k, ASIO drivers, and Kristal to record (freeware).

Can be had for $200 used, $275 new.  USB bus powered but external is possible.  Don't know what the power draw is but it doesn't seem to cut my laptop life much.  Unscientifcally I'd say I went from 4 hours of power (w/self powered UA-5) to 3.5 hours with the A62.

The main catch with multichannel audio interfaces is that you need to control gain properly in front of the device.  i.e. it takes line level signals and doesn't have any knobs to turn for more or less gain.  So if I'm recording the board and don't have a cooperative soundperson who's willing to turn the matrix output up or down, then I run the UA-5 in the chain just so I can control the levels.

Feel free to ask questions - not many people seem to have these as most tapers just do two track.  I got it after doing one too many sbd/mic mixes with sources clocked differently.  Makes life much easier when you don't have to deal with time drift.
