I have one of these M-Audio 410 jobbies


Unfortunately I dont have a power supply for it. I know it powers up from the firewire port but I dont know if that will supply power for mics etc that are connected to the interface. It needs a 12V 1000mA power supply but the box itself makes no mention of the polarity required from the power supply. If anyone has one closeby could they take a look at the power supply and let me know what the polarity of the supply is please

Hey dude, I think if you're using the unit as your main audio interface with the computer, then you should be fine using the firewire bus power.
I think you only need the power cable if you just want to use the mic preamps and feed the output to a different interface (i.e. your software doesn't see the the m-audio unit as an input(or at all for that matter)).
I can't be absolutely certain of this though, but sure, try it and see?...

I use one of these with firewire bus power. It sends phantom power to mic's no problem.

phantom power can be supplied to mics & DI boxes from the unit without power supply. bus power will do it no bodger.
Only if you're using big firewire to big firewire.
Small firewire doesn't supply bus power.
