Chapter 1: Introduction
The Dugan Model E-3A Automatic Mixing Controller helps professional audio mixers
handle multiple live mics without having to continually ride their individual faders.
This signal processor can be patched into the input insert points of an audio mixing
console. Then each mic channel is processed in the Dugan controller and returned
to the console for mixing. Alternatively, internal mix buses in the Model E-3A can be
used to sum channels.
The Dugan detects which mics are being used and makes fast, transparent cross-
fades, freeing the mixer to focus on balance and sound quality instead of being
chained to the faders. The Model E-3A crossfades unscripted dialogue which eliminates
cueing mistakes and late fade-ups. It also reduces comb filtering from adjacent mics
while avoiding the choppy and distracting effects common to noise gates.
The Model E-3A supports a broad spectrum of live mixing applications:
• Conference reinforcement, video trucks
• Houses of worship
• TV news and sports panels, reality and game shows
• Wireless mics for theater
• Boardrooms and civic meeting rooms
• Teleconferencing and distance learning
The Model E-3A includes three patented automatic mixing algorithms:
• Dugan Speech System™ reduces noise and feedback in dialog applications
• Dugan Music System
™ reduces ambient noise, bleed, and feedback when mixing a
musical group
• Dugan Gain Limiting
™ protects against feedback when using the Music System
