Behringer MONITOR2USB

High-End Speaker and Headphone Monitoring Controller with VCA Control and USB Audio Interface. When it's time to get down to the business of recording or mixing, you want the ultimate sound quality from your monitoring system - and the last thing you'll want is to crawl around under your desk running cables. The MONITOR2USB gets you off your knees and puts VCA-controlled Volume, Source selection, Phones and Monitor control right at your fingertips. With the incredible MONITOR2USB you can select from 3 sets of active studio monitors, 2 different stereo sources, plus a USB input for your DAW - to create powerful, custom monitor mixes - all in pristine, audiophile-grade sound quality. While MONITOR2USB's Volume control is mechanically similar to an analog control, its use of Voltage Controlled Amplifiers (VCA) provides several major benefits. First, since a DC current flows through the volume control (instead of the audio signal) there is no degradation in sound quality, and none of the pops and crackles typically produced by an audio-taper volume control. That current is what actually controls the levels of the separate left and right amplifiers. Second, both the left and right channels remain proportionately accurate to their input levels. Third, better left/right channel separation is maintained, because there are no audio signals present at the volume control. And finally, you get amazingly precise and repeatable level settings you can count on.
