DriveRack ® User Manual
Congratulations on your purchase of the dbx ® 220i! The dbx 220i processor was designed to provide
Installers with programmable system processing along with dbx’s Advanced Feedback Suppression™
(AFS™) algorithm for superior system control and performance. While the 220i offers all the tools
necessary for processing a system, from EQ and De-Essing to Limiting and Ducking, the thing that
sets this product apart from the competition is the inclusion of our patent-pending AFS™ algorithm
that offers feedback filters with Qs up to 1/80th of an octave. This ensures that the music, or speech
that comes in, goes out unblemished by the feedback detection and elimination process. In hundreds of
demonstrations of this patent-pending algorithms, people have tried to discern between the original and
processed signal, but to no avail.
Beyond the processing that the 220i is capable of, the 220i also offers control from the ZC series wall
panel controllers. These controllers provide convenient remote control capability of Program change,
Zone output volume and Muting. The zone controllers are easy to install using CAT5 cable and fit in
standard wall boxes.
This manual will be your guide to understanding the full functionality of the powerful 220i. By
combining the different components, the configuration possibilities are limitless. After you have become
familiar with the unit, we encourage you to experiment and find the most effective and efficient way to
run your system by utilizing the powerful processing of the 220i.
