Presonus Audio Box 1818VSL USB Recording Interface
$0.00
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.
