The Model 2000 Dugan Automatic Mixing System is designed to be the best sounding, most reliable auto-mixer in the world. The unit is designed around the patented Dugan Speech System. Other manufacturers have used this system, but tried to skimp on the circuit implementation. We at Protech have worked with Dan Dugan, to design the best possible circuits to utilize this patented approach to automatic mixing. Simply put, more gain and less echo pickup. The mechanical architecture of the Model 2000 is card frame based. Each module is individually fused. If a fault should occur, the module will remove itself from the power supply bus, allowing the remainder of the system to continue operating. It also allows microphone or line input circuits to be provided on a channel-by-channel basis. Each Model 2000 chassis can accomodate up to 8 input cards. Frames are linkable, to allow for larger systems. The input cards provide a wide variety of popular options, all user definable. Each input card also provides a balanced mix-minus output. The initial mix-minus outputs provide a total mix bus signal, minus that channel's input signal. Since each input module provides a mix-minus output, the system can have any number of custom mixes. It is not limited to 8 or 12 outputs. A system having 48 inputs would have 48 mix-minus outputs available. Each mix-minus output is configureable to allow separate mixes and mix levels at each output. This system allows maximum gain before feedback in each area of a room.
