The automatic mixer is designed specifically for small venues and rental service. The unit is designed around the patented Dugan Speech System. Much like an experienced console operator, the Dugan algorithm allows turning up the gain on an active channel, while simultaneously attenuating unused channels. By subtracting additional gain from unused channels, the unit reduces echo and redistributes that gain to active channels. This allows greater gain-before-feedback than gated mixers.

The Model 2016 adds 2 AUX inputs that are summed to a common signal that is adjustable via a front panel control. The AUX inputs can be switched between automatic and manual mode operation. Engineers at Protech Audio have worked directly with Dan Dugan to develop circuitry that accomplishes his algorithm economically and accurately, bringing transparent auto mixing to smaller installations.

The model 2016 utilizes a unique clip indicator circuit. The circuit uses a bicolor LED that indicates both signal presence and clipping at the summing bus. When an input is about to be overloaded the LED changes from a green to a red color.

The master output of the Model 2016 is transformer isolated. Remote control capability of the output level is built in. A simple 10K ohm potentiometer, mounted in a remote location, will control the output level. Placing a resistor in series with the remote potentiometer will restrict the overall range of the remote control.
