Edit Mode

The state in which the Aura’s eleven Parameters are accessible for building sound image/pickup mixes. Also the state in which the

Feedback Cancel feature can be preset for later recall.

An acronym for Musical Instrument Digital Interface; used to transfer downloaded Sound Image data between your home computer and

the Aura.

Mix or Sound Image / Pickup Mix

The blended combination of a Sound Image and a pickup signal, created by manipulating parameters in Edit Mode, and stored in a

program location in Play Mode.

Notch Filter

The proper name for the Feedback Cancel function. When the Feedback Cancel circuit identifies the resonant frequency of feedback, it

sharply attenuates that frequency in a way that graphically resembles a notch, hence the name.

Sound Image (or Digital Sound Image)

A sophisticated algorithm that transforms the response of a pickup into that of a microphone in front of a guitar (or other string

instrument). A Sound Image is constructed from actual recordings of actual instruments. To transform your instrument’s pickup signal,

this algorithm seamlessly adjusts the pickup signal’s phase and frequency response to match the selected Sound Image template. Also,

signature elements like body size, radiant sound from the guitar, body resonance, mic distance and microphone personality are all added

to the equation - providing amplified acoustic guitar sound with indisputable realism.
