MODELS 2004 & 2008

DUGAN AUTOMATIC MIXERS

INSTALLATION & OPERATION MANUAL

The Protech Audio Models 2004.2008 Automatic Micro-

phone Mixers are designed to be the best operating, most

transparent auto-mixers, for rental and portable applica-

tions as well as small venues. Both the 2004 and 2008

feature patented adaptive proportional gain sharing

control circuitry designed by Dan Dugan, the inventor

of automatic mixing. This operating system results in the

best, most transparent automatic mixing to be found

anywhere. Unlike gated mixers, or quasi-Dugan mixers,

the 2004 and 2008 operate on an elegantly simple prin-

ciple; each individual input channel is attenuated by an

amount, in dB, equal to the difference, in dB, between that

channel's level and the sum of all channel levels. The levels

are varied on a continuous basis, with no on-off actions, or

abrupt gain changes.

The 2008 features 8 switchable microphone/line level

inputs. The model 2004 features 4 similar inputs. Two

units may be linked together to create up to 16 inputs.

Both units feature a unique works-in-a-drawer construc-

tion. Access to all switches and push-on jumpers used

to configure various features, is achieved by loosening

the two thumbscrews located on each side of the front

panel, and sliding the entire electronics out of the chassis.

This easy access allows complete reconfiguration in just

minutes.

In addition to the input mode (mic/line) switch located at

each input, the gain of each input is configurable, via a

push-on jumper, to allow superior signal-to-noise opera-

tion. Moving the jumper over one pin changes the input

gain from 30dB to 50dB.

A bi-color LED is used to indicate signal presence and clip

threshold. Unlike other units, the clip indicator on the

Model 2008 indicates clipping of the summing buss, not

just an input, since it is possible to clip a summing bus,

without clipping an input.

Internal 15 volt phantom power is selected, on a channel-

by-channel basis, via a push-on jumper. When the input

mode slide switch is placed in the line position,

phantompower will automatically be disconnected, pre-

venting damage to line level devices.

The Models 2004 and 2008 also feature assignable group

mute function. Each input may be assigned to the mute

buss via an eight position DIP switch. Turning on a given

switch will assign that channel to the group mute.

Grounding the group mute control pin will mute the as-

signed channels.

The output level of the automixers may be controlled via

the front panel output potentiometer, or, assigned to a

remote potentiometer, via an on-board slide switch.

Both units have been designed with the operator in mind.

Control features allow the operator to attend to other

functions, without the need to continuously "ride gain".
