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, we record instruments using worldclass 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. [. . . ] Some pickup systems may not cause the light to flash at all and other onboard preamps may require you to turn their output down to achieve an optimum level. Phase Use the phase switch to improve bass response at low volume and suppress feedback at high volume. Move the phase switch and leave it in the position most pleasing to your ear.

Pickup EQ When shipped from our factory, the low, mid, and high tone controls are set to affect the sound of the pickup signal only. However, a Global EQ mode may also be selected which applies the same EQ settings to both the pickup and Image signals simultaneously (or "globally"). When you power on Aura Spectrum, watch the tuner display for a "P" or a "G" indicating the currently selected mode. To select Global EQ mode: 1.

The note name will be indicated as a single letter and a small # sign will be lit whenever the displayed note is raised one half step. The note being sharp, flat, or in-tune will be displayed using the five multi-colored LEDs in the tuner window and below the tuning note. [. . . ] If you can't find your exact instrument in the list, use the built-in Image Wizard to find the closest match. For example, if one of our hundreds of Images doesn't match your instrument exactly, you can still find a great sounding Image by matching similar tone woods and body styles. Experiment with these tools, and use your ears to determine what sounds best for your playing or musical style. To access this library of additional instrument Images, install the Aura Image Gallery on your computer. [. . . ]
