Chapter 1: Introduction
The Model E-1A Automatic Mixing Controller helps professional audio engineers
handle multiple live mics without continually riding individual faders. This multi-
channel audio signal processor patches into the channel insert points of a mixing
console. The Model E-1 detects which mics are being used, and makes fast, transpar-
ent crossfades. This eliminates late upcuts, reduces system noise and feedback, and
lets the engineer focus on balance and sound quality. The Model E-1A has both ana-
log and digital I/O connectors.
The Model E-1A enhances a diverse group of live applications that require multiple
mics:
• Conference reinforcement, video trucks
• Houses of worship
• Film and television dialogue, reality shows
• Theater
• Boardrooms, civic meetings, community TV
• Teleconferencing and distance learning
Several features expand the Model E-1A’s capabilities:
• 16-channel mode (option for digital interface only)
• Dugan Control Panel software offers additional controls
• Linking allows up to eight Dugan units to work as one large automatic mixer
Theory of Operation
The Dugan Model E-1A Automatic Mixing Controller uses the Dugan Speech System™,
a patented and trademarked automatic mixing function. This results in a natural
one-mic ambience with minimal noise or feedback. The Dugan Speech System does
not limit, compress, or control levels. It performs just one critical function: cuing mul-
tiple live mics in situations with unpredictable dialogue. It is essential to distinguish
this behavior from the distracting fluctuation of levels and uneven ambience pro-
duced by a conventional noise gate.
