Re: Opinions on AT 4022 Mic and ATI ML200 Pre-Amp

["Gregory O'Drobinak" gmo_dunes2]

A quick look at the Ati ML200 manual states that it requires a +24 - 30 volt 
power supply and the phantom power voltage is only 20.2 volts, unless you order 
it with a special option to add an internal inverter to get the full +48v 
phantom power [I'm sure that would add cost]. The self noise (according to B&H) 
is not bad at -124 dBm, but the other aspects of the power supply and lack of 
full phantom voltage would make it difficult to work with in the field. 

I woud consider finding a used Sound Devices preamp that works on 12 volts. 
Forget the ATi unit.
