PreSonus has raised the bar high for audio interfaces with the introduction of the AudioBox 22VSL, AudioBox 44VSL, and AudioBox 1818VSL. For the first time, you can get a compact, rack-mountable USB 2.0 interface with tightly integrated software that provides the dynamics processing and EQ of a StudioLive™-series mixer with latency so low that you can record and monitor with effects in real time.
