The AirAura audio processor features proprietary AirAura final clipper technology for cleaner, clearer, more natural mid and high end detail without smearing, dulling and other artifacts commonly associated with managing the FM pre-emphasis curve. AirAura's 2.0 upgrade features the latest Vorsis Bass Management System (VBMS) with new Bass Tools for adding “floor” feel to the bottom end. It creates a virtual subwoofer in the 40Hz- 90Hz range to give your listeners bass they can feel – perfect for CHR and Urban programmers.
