FEATURES: THE MODEL D AUTOMATIC MIXING CONTROLLER IS A BREAKTHROUGH PRODUCT THAT EXTENDS THE
CONVENIENCE OF AUTOMATIC MIXING TO PROFESSIONAL SOUND MIXERS. THE EIGHT-CHANNEL
CONTROLLER PATCHES INTO YOUR AUDIO CONSOLE TO PROVIDE SMOOTH AUTOMATIC MIXING OF
MULTIPLE LIVE MIKES. YOU WON'T BE CHAINED TO THE FADERS ANY MORE, BECAUSE THE MODEL D
KNOWS WHO'S TALKING. IT FREES YOU TO FOCUS ON BALANCE AND SOUND QUALITY. USERS FIND IT
INVALUABLE FOR BROADCASTING, SOUND REINFORCEMENT, RECORDING, AND LIVE PERFORMANCE
SITUATIONS. THE MODEL D'S TRANSPARENT, VOICE-CONTROLLED CROSS-FADES FOLLOW UNPREDICTABLE
DIALOGUE FLAWLESSLY, ELIMINATING LATE FADE-UPS WITHOUT THE CHOPPY EFFECTS OF GATING. BUILT IN
EXPANDABILITY LETS YOU LINK UNITS FOR UP TO 96 CHANNELS TO HANDLE THE BIGGEST JOBS.

THE MODEL D MARKS INVENTOR DAN DUGAN'S SECOND MAJOR AUDIO PRODUCT INNOVATION. IN
1973, DUGAN PATENTED THE FIRST AUTOMATIC MICROPHONE MIXER. SINCE THEN AUTOMATIC
MIXERS, DUGAN'S INVENTION, HAVE BECOME A MAJOR PRODUCT CATEGORY. NOW, DUGAN'S MODEL
D FILLS ANOTHER MARKET VOID WITH ITS AUTOMATIC MIXING CONTROL FUNCTIONS. THE MODEL D
INCORPORATES THREE DUGAN-PATENTED TECHNOLOGIES TO OFFER A UNIQUE SET OF MIXING
CAPABILITIES. FIRST, THE DUGAN SPEECH SYSTEM AUTOMATICALLY MANAGES ANY NUMBER OF LIVE
MIKES IN UNSCRIPTED TALKING SITUATIONS. SECOND, THE DUGAN MUSIC SYSTEM OFFERS AUTOMATIC
SOFT-MUTING TO HELP REDUCE FEEDBACK AND NOISE PICK-UP IN LIVE PERFORMANCES, SUCH AS
OPERA OR FOR ROCK CONCERT BACK-UP VOCALISTS. THRESHOLDS ARE ADJUSTED AUTOMATICALLY
THROUGH CONTINUOUS MONITORING OF AMBIENT NOISE LEVELS. THE THIRD SYSTEM, THE DUGAN GAIN
LIMITING SYSTEM, PROVIDES A CONTINUOUS, STEP-LESS, NUMBER-OF-OPEN-MICROPHONES MASTER
GAIN ADJUSTING SYSTEM TO PREVENT FEEDBACK AND AMBIENT NOISE BUILD-UP WHEN USED WITH
EITHER THE MUSIC SYSTEM OR WITH MANUAL OR REMOTE MIKE SWITCHING. THE COMBINATION OF
THESE THREE DUGAN TECHNOLOGIES MAKE THE MODEL D A UNIQUE TOOL FOR THE INDUSTRY. THE
MODEL D'S PROFESSIONAL CONNECTORS AND MARKED DEFAULT CONTROL SETTINGS ALLOW YOU TO HAVE
IT UP AND RUNNING WITH YOUR CONSOLE IN MINUTES.

HOW IT WORKS:

THE DUGAN SPEECH SYSTEM AUTOMATICALLY MANAGES ANY NUMBER OF LIVE MIKES IN AN
UNPREDICTABLE DIALOGUE SITUATION. THE ABOVE ILLUSTRATION SHOWS THE SPEECH SYSTEM IN
ACTION, OFFERING FOUR SNAPSHOTS OF A THREE MIKE SYSTEM UNDER DIFFERENT CONDITIONS OF
STIMULATION. FOR INSTANCE, IN THE FIRST FRAME NO ONE IS SPEAKING, SO THE INPUTS ARE RIDING AT
A MEDIUM GAIN, ADDING UP TO THE GAIN OF ONE MIKE. IN THE SECOND FRAME, ONE PERSON IS
SPEAKING. YOU'LL NOTICE THAT THE GAIN AUTOMATICALLY TURNS UP FULL, WHILE THE OTHER INPUTS ARE
TURNED DOWN. IN THE THIRD FRAME, ANOTHER PERSON SPEAKS AND THE GAIN AUTOMATICALLY SHIFTS
TO THAT INPUT, WHILE THE OTHER INPUTS ARE TURNED DOWN. AND IN THE FOURTH FRAME, WHEN TWO
PEOPLE SPEAK SIMULTANEOUSLY, THE GAIN IS AUTOMATICALLY SHARED BETWEEN THEM, WHILE THE
THIRD IS TURNED DOWN.

IN THE DUGAN MUSIC SYSTEM, EACH CHANNEL HAS AN EXPANDER GATE WITH AN AUTOMATICALLY
VARYING THRESHOLD. THE GATE THRESHOLDS FOLLOW THE SOUND LEVEL PICKED UP BY AN AMBIENT
SENSING MIKE.

THE DUGAN GAIN LIMITING SYSTEM IS USED WITH THE MUSIC SYSTEM TO PREVENT FEEDBACK OR
NOISE BUILD-UP WHEN SEVERAL MIKES ARE IN USE. IT DOESN'T JUST COUNT HOW MANY MIKES ARE
ON, IT CONTINUOUSLY MONITORS THE TOTAL GAIN OF THE SYSTEM AND REDUCES ALL INPUTS SMOOTHLY .
YOU DECIDE, BY SETTING THE GAIN LIMIT, HOW MANY MIKES CAN COME ON BEFORE GAIN
REDUCTION BEGINS.

WHAT DISTINGUISHES THE MODEL D FROM ALL OTHER AUTOMATIC MICROPHONE MIXERS IS ITS ABILITY
TO BRING YOU THE HIGHEST QUALITY OF SOUND IN DEMANDING AND ARTISTIC APPLICATIONS. A QUICK
GLANCE AT THE MODEL D'S FRONT AND BACK PANELS SHOWS THAT THE PRODUCT IS IN A CLASS OF ITS
OWN. ITS RICH ARRAY OF CONTROLS PROVIDE YOU WITH THE TOOLS YOU NEED TO FINE-TUNE THE SYSTEM
FOR THE WIDE SPECTRUM OF AUDIO CONDITIONS YOU ENCOUNTER. FOR EXAMPLE, THE "LAST HOLD"
FUNCTION PROVIDES CONTINUOUS AMBIANCE WHEN DESIRED WITH THE MUSIC SYSTEM. THE "AUTO
MIX DEPTH" CONTROL SETS THE AMOUNT OF AUTOMATIC ATTENUATION. IF YOU SELECT THE "OVERRIDE"
BUTTON, IT FADES THE SYSTEM TO THE COMBINATION OF INPUTS SELECTED BY THE OVERRIDE PRESET
SWITCHES ON EACH CHANNEL. THE MODEL D'S "PRESET" BUTTON SHIFTS THE SYSTEM SMOOTHLY TO
YOUR DEFAULT COMBINATION OF ON, AUTOMATIC, AND OFF MODES FOR THE CHANNELS AS
PROGRAMMED ON THE PRESET SWITCHES. THIS COMBINATION ALSO COMES UP WHEN POWER IS
TURNED ON. A MOMENTARY "MUTE" BUTTON ALSO ALLOWS YOU TO SMOOTHLY DUMP ALL CHANNELS
WITHOUT DISTURBING OTHER SETTINGS.

THE MODEL D'S EIGHT INPUTS AND EIGHT OUTPUTS ARE LOCATED ON THE UNIT'S BACK PANEL, ALONG
WITH THE MUSIC SYSTEM THRESHOLD INPUT. THE REMOTE CONTROL CONNECTORS ALLOW YOU TO EASILY
WIRE UP REMOTE CONTROLS FOR THE MAJOR FUNCTIONS OF THE MODEL D. MULTIPLE UNITS CAN BE
DAISY-CHAINED USING THE LINK CONNECTORS. CONNECTIONS ARE ALSO PROVIDED FOR AN UPCOMING
DUGAN AUTOMATIC LEVEL CONTROL PRODUCT THAT WILL FURTHER EXTEND THE CAPABILITIES OF THE
MODEL D.

BUILT BY AN AUDIO MIXING PROFESSIONAL FOR OTHER PROFESSIONALS, THE MODEL D COMES WITH
ALL THE QUALITY AND CONVENIENCE FACTORS YOU'D EXPECT TO HAVE IF YOU DESIGNED THE SYSTEM
YOURSELF. THE MODEL D'S CIRCUITRY IS MADE IN THE U.S.A., AND IS MODULAR FOR EASY
SERVICING. ALL IC'S ARE SOCKETED. THE UNIT IS DESIGNED TO MEET APPLICABLE NATIONAL SAFETY
STANDARDS. THERE'S A HARD-WIRE BYPASS RELAY IN EACH CHANNEL SO THAT IF POWER IS LOST TO THE
UNIT, ALL CHANNELS ARE PATCHED THROUGH. INDIVIDUAL POWER REGULATION FOR EACH CHANNEL
FURTHER ENSURES THE SYSTEM'S RELIABILITY.
