Introduction

Welcome!

Thank you for purchasing the Alesis DEQ830. It is a versatile product, and whether it becomes a part of your studio or finds its place in your live setup, we know it will serve you well. Since 1984, we’ve been designing and building creative tools for the audio community. We believe in our products, because we've heard the results that creative people like you achieve with them.

One of the goals of Alesis is to make high-quality music technology available to everyone. This Reference Manual is an important part of that, because in it we try to present the DEQ830’s features in a way that is easy to understand and remember. But even beyond explaining each feature and parameter, this manual can be a key that unlocks an application for the DEQ830 that you may not have considered. So we try to write our manuals as carefully as we build our products.

The goal of this manual is to get you the information you need as quickly as possible, with a minimum of hassle. We hope we've achieved that. If not, please drop us an email and give us your suggestions on how we could improve future editions of this manual.
