What is Aura?

Aura Acoustic Imaging Technology uses digital algorithms developed in Fishman’s audio laboratories to restore a studio-miked sound to an acoustic instrument. To achieve this, Fishman recorded instruments using world-class microphones and techniques to capture an “Image” of the natural sound that your acoustic instrument emits when miked in a professional studio. This Image, when recorded direct or played through an amp, mixer or PA, blends with your instrument’s pickup to produce an incredibly accurate recreation of the original recording.

Aura Acoustic Imaging processors sound best when used with Fishman undersaddle pickups and magnetic soundhole pickups. When Fishman record each instrument, they used their Acoustic Matrix undersaddle pickup. So, when you play through an Aura processor, you’ll get the best results using the Acoustic Matrix pickup. It's not recommended to use soundboard-mounted pickups, bridge-plate pickups, multi-sensor pickups or microphones for Aura products since they include unnecessary resonances that can interfere with the Aura processing
