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.
