X-VCA dynamics control

Introduction

The X-VCA includes a number of features for control of signal dynamics in both the Audio Group and Master sections. In many situations, these on-board features elimi- nate the need for outboard dynamics processors.This not only reduces costs and con- serves rack space, but also allows operators to keep their attention focused on the console at all times.

Note: The following material is not intended to serve as a comprehensive discussion of general principles and techniques involved in dynamics processing. The content here is restricted to the specific controls and applications of the X-VCA. It is assumed the operator is familiar with general approaches to dynamics processing.
