PreSonus Audiobox 1818VSL

The Presonus AudioBox 1818VSL is a USB 2.0 audio and MIDI interface that packs a wealth of features and functionality into a single chassis. The interface uses computer CPU and Virtual StudioLive™ (VSL) software to provide delay and reverb effects, compression, limiting, semi-parametric EQ, and a high-pass filter.

Internally, the Audiobox 1818VSL utilizes 24-bit/96kHz converters, MIDI I/O, Class A XMAX™ preamps, S/PDIF coaxial I/O, ADAT optical I/O, and a word-clock output. There’s also a 26x8 software mixer, meaning users can mix a session or live band while monitoring and recording! This effectively negates the need for external hardware mixers and outboard effects racks, as users have the option of using the 1818VSL’s internal effects as well.

Great care has been taken to reduce latency as much as possible. Consequently, the Audiobox 1818VSL is capable of perpetrating dynamics processing, reverb, EQ, and realistic effects without any audible delay. This means that musicians can play in tandem with a track while listening without being thrown off by unwanted aural fluctuations.
