AGDE-E20 : Premium Digital Audio Signal Processing Module
AGDE-E20 Overview
The AGDE, Altonics Genuine Digital Effect is Altonics’ newest line of high-quality/performance multi effects
processors. Although many users of the AGDE-E20 will be looking for a solution for high-end multi-effectors or
guitar & bass related sound processing, the wide range of effects provided by the AGDE-E20 is suitable for
various applications including mixers, karaoke amplifiers and other sound enhancement products.
Instilled with Altonics’ about 20 years of know-how in digital sound processing, the AGDE-E20 provides the
best audio quality and performance possible for whichever application you choose. With the Altonics name
behind it, you know you can trust the quality of this audio signal processor.
The AGDE-E20 is an all-in-one effects solution. It supports filters that can be used for such as EQ, spatial
effects such as delay and reverb, the whole range of modulation effects including chorus, flanger, phaser, wahwah, tremolo, auto pan, vibrato and more. It also encompasses dynamics processing with a noise gate,
compressor, and limiter. Fuzz, overdrive, and distortion are all provided in their full crunchiness while still
maintaining crisp clear digital sound. Of course, a chromatic tuner can be provided. By real-time 32-bit digital
processing, and you won’t need to look any further for all your sound enhancement needs.
In the following pages you will find our reference design implementing AGDE-E20’s functions to the fullest.
Just pick the functions you want and match them with your custom control and display.
