PreSonus AudioBox 1818VSL

A professional recording system you can grow with.

When you’re recording a full band, you need an interface with enough I/O to handle the challenge. For these sessions, the AudioBox 1818VSL USB 2.0 audio/MIDI interface has you covered with six mic/line inputs and two mic/instruments inputs, each with a crystal-clear, high-headroom XMAX preamp. Want to track the whole band at once and send to multiple sets of monitors, headphone amps, and outboard gear? Connect a PreSonus® DigiMax™ D8 or DigiMax DP88 8-channel preamp/converter via ADAT Optical and a digital device via S/PDIF for a total of 18 inputs and 18 outputs.

XMAX preamps + 96 kHz sampling = great sound.

The AudioBox 1818VSL records and plays back at sampling rates up to 96 kHz, with remarkably low noise. It features the same Class A XMAX microphone preamplifiers as our StudioLive AI mixers, which are found in recording studios and live venues the world over. The result is clean, pure, audiophile-quality sound.

A versatile solution for almost any studio.

The AudioBox 1818VSL’s two combo mic/instrument and six combo mic/line inputs make it extremely versatile, enabling you to use it with microphones, guitars, keyboards, DJ gear, and more. But that’s just the start: The 1818VSL is loaded with features that make it suitable for almost any studio situation and on the road.

World-class recording software included.

Seamlessly integrated with the included PreSonus Studio One® 3 Artist DAW, the AudioBox 1818VSL interface works with virtually all Mac and Windows audio-recording software. Built by creative people for creative music production, Studio One 3 is easy to learn and enables you to compose, record, and produce your masterpiece without getting distracted by the tools.
