The Presonus AudioBox 44VSL — The Most Powerful 4-Channel Interface in it's Class.

If you’re looking for a professional audio interface with only a couple of inputs, look no further than the PreSonus AudioBox 44VSL USB Audio Interface. Part of the VSL series, the 44VSL offers tons of great useful features for the money. The AudioBox 44VSL is great for everything from project studios and performing bands to school music labs and corporate and contractor applications.

Virtual Studio Live

At the heart of the AudioBox 44VSL is the Virtual StudioLive™ software (hence VSL in the name). VSL is truly a breakthrough achievement in hardware and software integration. VSL takes the core concept and features of the StudioLive™ 16.0.2 digital mixer and brings it to the AudioBox 44VSL. Through an innovative driver/software design, Presonus has made near zero latency mixing and DSP processing of inputs possible over a USB 2.0 connection. Unlike some other audio interfaces on the market that have expensive processing chips within the hardware itself, the VSL software on the host computer handles all mixing and processing, all while keeping latency at a maximum of 6ms or less.

VSL features the same Fat Channel processing as the StudioLive 16.0.2 digital mixer. Each channel has a variable high-pass filter, 3-band semi-parametric EQ, compressor, and limiter. These can be either printed to your recordings or used solely for monitoring purposes. VSL also has 2 FX buses with 50 different reverb and delay presets. Awesome!

AudioBox 44VSL Features:

  • High-End 24-bit, 96 kHz converters (+114db dynamic range)
  • 4 Class A XMAX preamps
  • 4 assignable line outputs + main monitor outputs
  • MIDI I/O
  • Heavy-Duty metal chassis
  • 8x4 software mixer
  • High-powered 120 mW headphone output

The 44VSL is both versatile and portable and enables you to manage processing and mixing from your Mac or PC. With two front-panel mic/instrument combo inputs, MIDI inputs, Virtual StudioLive, and Studio One Artist, you get more for your money than any other interface at this price point.

The VSL series products are integrated with PreSonus’ Studio One Artist DAW and VSL. Each model works with all Mac and Windows audio recording software.

*Note that the speed of your processor, amount of RAM and size and speed of your hard drive will greatly affect the overall performance of your recording system.
