Dugan Speech System
The Dugan Speech System is a patented and trademarked automatic mixing function.
The Speech System distributes the gain of one open microphone over the entire system,
maintaining a natural ambience. This is nothing like the annoying fluctuation of levels
and uneven ambience in a conventional gating system.
The system automatically manages any number of live mics in unpredictable dialogue
situations. When one person speaks, that mic’s gain fades up instantly, and the others
down. When the speaker pauses, all mics fade to medium gains that sum to equal one
mic at full gain. The result sounds like passing one mic around among the speakers.
When several people talk at once, the gain is shared.

Figure 2-1 shows the Speech System automatic mixing in action with a three-mic
system with no speaker, one, and two speakers:
• No one speaking : The sound levels at all mics are low. The system fades all channels
to medium gains that sum to the equivalent of one mic at full gain.
•
One person speaking
: The system fades their gain to full, while fading down the
other two inputs.
• A different person speaking : The system fades their gain to full, while fading
down the other two inputs.
•
Two people speaking
: The system shares the gain between them, while fading
down the other input.
