Lectrosonics DC1 - Manual (Page 2)

INTRODUCTION
The DC1 is a sophisticated, microprocessor-based audio signal processor which will add the capability of automatic
mixing to any standard mixing console. The DC1 provides the capability to automate up to 4 standard channels.
Since more than one DC1 may be used together, any number of channels may be automated. The DC1 is
intended for use in any system that already has a standard mixing console, but where automation on some
channels is helpful. Examples might be TV and radio broadcast studios, large churches, etc.
The DC1 uses Lectrosonics’ unique "Adaptive Proportional Gain" mixing algorithm rather than hard switching to turn
channels off and on. This results in totally inaudible automatic action. Complete control over all operational
parameters is afforded by the DC1. The actual automatic mixing algorithm is implemented in software, and as a
result much greater control and flexibility may be exercised than would normally be the case in a purely analog
system.
