The AudioBox 22VSL from PreSonus is a portable 2 input/2 output USB 2.0 audio and MIDI interface that allows for monitoring with low-latency effects. It features two combo microphone/instrument inputs with Class-A XMAX microphone preamps, and ships with Studio One Artist DAW software.
The compression, limiting, semi-parametric EQ, high-pass filter, reverb, and delay effects are the same as found on the company's StudioLive 16.0.2 mixer. Additionally, the AudioBox Virtual Studio- Live "kernal mode" cuts monitoring latency to under 2 1/2 milliseconds, which is virtually inaudible.
The unit is USB bus-powered and housed in a ruggedly built, metal chassis. Phantom power can be switched globally. Clip lights are provided for both channels
