The UAX220-Mic is a professional stereo USB Audio interface designed for broadcast and other demanding pro audio applications that require high quality audio acquisition of microphone level signals. Because it is USB Audio compliant, it can be used with multiple computers (laptop or desktop) and thrid party software applications without installing a dedicated driver.
UAX220-Mic offers 2/2 balanced analog high-quality I/Os. Thanks to the professional grade mic preamps and switchable +48V phantom power on each input, UAX220-Mic is the most efficient Pro Audio interface for portable use.
