A professional audio interface that’s just the right size.

We don’t want to push the Goldilocks analogy too far but if two-channel audio interfaces are too small for your needs, and interfaces with eight or more channels are overkill, then our four-in, four-out AudioBox® 44VSL will be just right. With the AudioBox 44VSL and included Studio One® Artist software, you can record up to four tracks at a time with professional-caliber 24-bit, 96 kHz audio quality, using crystal-clear, high-headroom XMAX; preamps. And the AudioBox 44VSL is ready to travel, thanks to a rugged, compact enclosure, so you can create your next hit in your personal studio or your hotel room.

XMAX preamps + 96 kHz sampling = great sound.

The AudioBox 44VSL features the same award-winning Class A XMAX preamps featured in our StudioLive AI mixers, found in recording studios and venues the world over. Record and play back at sampling rates up to 96 kHz, with remarkably low noise. If that’s all geek to you, here’s the simple version: This thing sounds great.

What’s so great about an XMAX preamp?

The microphone preamplifier is a key component in the audio quality of a recording, and all mic preamps are not created equal. The AudioBox 44VSL includes custom-designed, high-voltage, discrete, XMAX Class A microphone preamplifiers that are suitable for use with all types of microphones.

The job of a microphone preamplifier in an audio interface is to boost a microphone-level signal to line level before conversion to the digital domain. A good preamp boosts the level to almost 400 times that of the original signal, making the preamp one of the most important stages in an interface. Inexpensive or poorly designed preamps can lead to thin, noisy, or even harsh and brittle results. But with XMAX preamps, the sonic quality is limited only by what microphone you plug into it.

XMAX preamplifiers are built with three key elements:

  • Class A. Class A circuits have no crossover distortion and deliver purer, clearer, and more musical results than the Class AB designs that are found in many preamps.
  • High Voltage. The XMAX preamplifier runs on power rails of 30V. Most off-the-shelf, op-amp-based designs run on power rails of 10V to 18V. Higher-voltage power rails deliver more headroom, deeper lows, smoother highs, and a richer overall sound.
  • Discrete components—not op-amps. We only use genuine transistors, resistors, and capacitors. Op-amps add noise, coloration, and harshness to a signal. Our discrete design delivers ultra-low noise and transparency.

The net result of the XMAX preamp design is high headroom, low noise, wide dynamic range, extended frequency response, and—most important—musicality and transparency.

Perfect for small bands, DJs, and just about everyone else.

The AudioBox 44VSL’s two combo mic/instrument and two combo mic/line inputs make it extremely versatile, enabling you to use it with microphones, guitars, keyboards, DJ gear, and more. A mix control blends the input signal with the computer playback stream for zero-latency monitoring so you can overdub new tracks without hearing annoying delays. With its MIDI I/O, you can connect the AudioBox 44VSL to virtually any standard MIDI instrument or control surface. And you get four line-level audio outputs, enabling you to simultaneously feed and switch between two sets of monitor speakers or DJ gear.

These features make the AudioBox 44VSL a simple, affordable solution for small bands, DJs, school music labs, and virtually all instrumentalists.

Roadworthy and ready to travel.

We gave the AudioBox 44VSL a heavy-duty steel chassis and metal knobs, so it can take a serious pounding and remain completely reliable. Its screaming-loud headphone output ensures you can hear your music loud and clear, even in noisy locations. And despite all of its controls, preamps, and I/O, somehow we managed to shoehorn the AudioBox 44VSL into a half-rackspace case that can be screw-mounted to a standard rack tray (not included).

SPL Attacker is a micro-plug-in that employs the same Differential Envelope processing technique as SPL’s famed Transient Designer. Using SPL Attacker, all attack events can be amplified, regardless of their signal level. By focusing on the initial transient instead of specific frequencies, SPL Attacker amplifies just the attack curves of a sound event. This allows instruments to be mixed at lower levels, which opens up space in the mix, while the relationship between tracks is preserved.

Mäag Audio EQ2 delivers the sound of the Mäag Audio EQ2 two-band hardware equalizer. Mäag Audio’s EQ design allows for exceptionally low phase shift across all EQ adjustments, which helps maintain the integrity of your mix’s original sound while enhancing the very high “air” frequencies. An input attenuator lets you normalize levels after applying EQ.

Lexicon’s MPX-i Reverb delivers seven classic Lexicon plate, hall, chamber, and room reverbs. A streamlined interface and 25 versatile, finely crafted presets enable you to quickly get the sound you want. Input and output metering let you monitor levels at a glance.

The Eventide H910 plug-in is a faithful re-creation of the classic H910 Harmonizer, which offered unique combinations of pitch shifting, modulation, and delay. Use pitch changing to create specific musical intervals and perfect harmonies, spread guitars, fatten snares, apply subtle organic detuning to synths, and add slap-back delays to vocals.

Also from Eventide comes the 2016 Stereo Room, which delivers a natural, yet distinctive-sounding reverb that can be lush or subtle. Derived from Eventide’s SP2016 hardware processor, its simple, intuitive controls allow you to fine tune your virtual space, from a dark hallway to a bright studio vocal room. Use multiple instances to bring out the character of different parts of a track.

The Brainworx bx_opto compressor combines the best aspects and anomalies from several legendary, light-dependent compressor circuits. The result is a powerful dynamics processor, teeming with character and delivering sounds that can’t be achieved with analog optical compressors.
