Advanced 4x4 USB 2.0 Audio Interface

Presonus AudioBox 44VSL introduces a new generation of PreSonus USB 2.0 audio/MIDI interfaces that take hardware/software integration to the logical next step. Using your computer CPU and PreSonus Virtual StudioLive (VSL) software, AudioBox VSL-series interfaces provide reverb and and delay effects and the same Fat Channel compression, limiting, semi-parametric EQ, and high-pass filter, as the PreSonus StudioLive 16.0.2 digital mixer— all with inaudible latency. Now you can monitor and record with or without real-time dynamics processing and EQ!

Tracking without hearing effects and signal processing is like playing a video game with your eyes closed. Musicians rely on aural cues when performing, and their performance can vary depending on what they hear in their monitors. Adding just the right amount of compression, EQ, and reverb can make a huge difference in their ability to hear themselves clearly and to experience their performance as if it occurred in a natural space rather than in the artificial sonic environment of the studio. The result is a better performance and ultimately a better recording.

You have plenty of effects plug-ins for your DAW, but processing audio with a DAW takes more time than you might think. True, we’re talking milliseconds, but it’s long enough that if you put DAW effects in your studio monitors, you’ll hear the original sound slightly before the processed signal, which is very disorienting. That much delay might be acceptable for live gigs, where the band is playing together in an ambient space that has natural delay. But you can’t record that way in the studio.  Fortunately, our engineering wizards have dramatically reduced processing delay in the AudioBox VSL series. The result: dynamics processing, EQ, reverb, and effects that feel real, with no audible delay.  And if you like what you hear, you can record with AudioBox VSL-series effects, too! These are the same high-quality StudioLive 16.0.2 Fat Channel dynamics processors and EQs that professional musicians, engineers, and producers record with every day.

Compact and rugged, the AudioBox 44VSL offers two convenient front-panel mic/instrument combo inputs and two mic/instrument combo inputs, global phantom power, and a total of six line-level outputs. It sports the same high-headroom, Class A XMAX preamps as the StudioLive mixers and has 24-bit, 96 kHz converters with 114 dB dynamic range for clear, clean audio. And it boasts PreSonus’ legendary 150 mW headphone output. 

PreSonus gear has a well-earned reputation for extreme roadworthiness, and the AudioBox 44VSL is no exception. It employs a heavy-duty steel case that is every bit as rugged as that of the smaller AudioBox 22VSL and original AudioBox USB.  It fits in a half-rackspace and can be screw-mounted to a standard rack tray (not included).
