Product description from ZOOM:

The LiveTrak™ L-20 is the new digital console offering everything creators need to mix, monitor, and record complex productions. With 20 discrete audio channels and six individual custom monitor mixes, it’s built for bigger, bolder arrangements

Although the LiveTrak L-20 is designed to work as a stand-alone recording and mixing console, it can also be used as a 22-in/4-out USB audio interface. Audio Interface mode lets you route inputs to any DAW or streaming software, even while recording to an SD card. Additionally, audio can be routed from your computer into the L-20 to be mixed with your live performance. Class compliant mode, which enables connection with iOS devices, is supported as well.
