Exceptional audio quality:From the XMAX microphone preamps to the high-resolution 24-bit/96kHz converters, the PreSonus AudioBox 1818VSL’s audio quality belies its price. XMAX preamps run on 30V power rails, while most budget preamps run on 10V-18V. The higher voltage gives you more headroom and a richer overall sound.
