Dugan Model E-2 User Guide 8
Dugan Model E-2 User Guide Chapter 1: Introduction The Model E-2 Automatic Mixing Controller helps professional audio mixers handle multiple live mics without having to continually ride their individual faders. This signal processor patches into the input insert points of an audio mixing console. It detects which mics are being used and makes fast, transparent cross-fades, freeing the mixer to focus on balance and sound quality instead of being chained to the faders.
Dugan Model E-2 User Guide Dugan Speech System Theory The Dugan Model E-2 Automatic Mixing Controller uses the Dugan Speech System™, a patented and trademarked automatic mixing function. The Dugan Speech System distributes the gain of one open microphone over the entire system, maintaining a natural one-mic ambience. It is essential to distinguish this behavior from the annoying fluctuation of levels and uneven ambience in a conventional gating system.
Dugan Model E-2 User Guide Introduction Dugan Music System and Gain Limiting Theory These functions require the physical Model CP-2 or Dugan Control Panels for Java or iPad. See Dugan Music System and Gain Limiting on page 51 for more information on setting up the Music System. Dugan Music System The Dugan Music System is a soft-gating or ducking system with its threshold set by an audio side-chain, typically from a mic measuring the ambient sound level.
Dugan Model E-2 User Guide Gain Limiting Gain Limiting reduces master gain as new mics enter the system, thus avoiding feedback and noise. This is commonly called NOM (Number of Open Mics) gain adjustment. Unlike NOM functions on other systems, Dugan Gain Limiting doesn’t just count how many mics are on. It sums the gains of all active channels (including partially attenuated channels), compares them to a gain threshold, and reduces the gain appropriately.
Dugan Model E-2 User Guide Introduction Model E-2 Modes The Model E-2 is an eight-channel audio processor offering three Dugan algorithms. However, it can operate in twelve- or sixteen-channel modes with reduced features. See Chapter 3: Installation and Configuration to learn how to choose a mode with the #ch button during installation. Eight-channel • The Dugan Speech System™ provides automatic mixing for eight live mics.
Dugan Model E-2 User Guide 14
Dugan Model E-2 User Guide Chapter 2: Quickstart This section provides step-by-step instructions to help you get started quickly using the Dugan Speech System to mix up to eight channels. Twelve- and sixteen-channel I/O is available using the Dugan Control Panel software. See Chapter 5: Dugan Control Panel Software to learn about these options. 1. Connect the provided power supply to the Model E-2. 2. Hold the channel 1 bypass button down and power up the unit.
Dugan Model E-2 User Guide stays lit green Figure 2-2 Setting console preamp gain 6. With the room quiet, raise your console preamp gains until the Model E-2’s green level LEDs stay illuminated. The level LED illuminates green when the input level is within the acceptable range for automatic mixing and flashes red to indicate clipping. There should be enough gain ahead of the Model E-2 to maintain the green LED at all times.
Dugan Model E-2 User Guide Installation and Configuration Chapter 3: Installation and Configuration We recommend placing the Model E-2 in a convenient place in the engineer’s line of sight. Figure 3-1 Model E-2 placed conveniently Rack Mounting All E-Series Dugan controllers are a half-rack wide, so one or two can be mounted in a single rack space. Each unit ships with one long and one short rack ear and one joining plate.
Dugan Model E-2 User Guide Power Supply Units shipped to the USA include a 12 V, 1.5 A, 120 VAC power supply. Contact the factory if you require a different power supply. In an emergency, the Model E-2 can accept power supplies within the following ranges: • 12–24 VDC, either polarity, 1.5 A • 9–18 VAC, 1.5 A System Reset Hold down the channel 1 bypass button and power up the unit. Keep holding the bypass button down for about three seconds until the unit finishes booting.
Dugan Model E-2 User Guide Installation and Configuration Rear Panel I/O Connections The Model E-2 provides the following rear panel I/O connectors: • AUDIO I/O 1–4 • AUDIO I/O 5–8 • AUDIO I/O 9–12 Each DB25 connector carries four input and four output analog channels. All analog audio connections are balanced. To connect with XLR connectors, use readily available adapter squids. Although the Model E-2 uses these connectors for analog I/O, they are wired according to the TASCAM digital standard.
Dugan Model E-2 User Guide Analog Move the ANA-DIGI switch to ANA (up position). If you do not need the Dugan Music System, twelve channels of automixing are available using all three DB25 connectors. The content of the AUDIO I/O 9–12 DB25 connector depends on the state of the #ch switch. This can be set in the Dugan Control Panel (see Chapter 4: Dugan Control Panel) or with a power-up command (see Appendix A: Power-up Commands).
Dugan Model E-2 User Guide Installation and Configuration Digital Move the ANA-DIGI switch to the DIGI (down) position. This switches the I/O to the ADAT connectors. The state of the #ch switch determines the I/O count and linking capability. This can be set in the Dugan Control Panel (see Chapter 4: Dugan Control Panel) or with a power-up command (see Appendix A: Power-up Commands).
Dugan Model E-2 User Guide Linking Up to eight Dugan units can be linked into a single automatic mixing system. The audio I/O for each must be configured and connected individually. Linking passes only control information between Dugans, not audio. One unit must be set to be the master and the others slaves. 1. Designate one unit as the master by setting the NORM–SLAVE switch on the rear panel to NORM (up). 2.
Dugan Model E-2 User Guide Installation and Configuration Mix Matrix Outputs In eight-channel mode, an internal mix matrix can route processed or unprocessed inputs to four mix bus outputs on the AUDIO I/O 9–12 connector. For more information on using mix buses, see Mix Bus Matrix on page 49. Connecting the Model CP-2 Control Panel The Dugan Model CP-2 Control Panel hardware can be connected to the four-pin mini-XLR connector.

Dugan Model E-2 User Guide Chapter 4: Stand-alone Operation This chapter tells you how to operate the Model E-2 stand-alone (i.e., without the physical Model CP-2 Control Panel or the software Dugan Control Panel for Java or iPad). Settings 1. Put all the live mic channels in automatic mixing mode by deactivating bypass and mute. 2. Activate the mute buttons for all unused channels. Figure 4-1 Channel controls 3.
Dugan Model E-2 User Guide 4. Set the console faders to your normal operating positions. 5. Balance the preamp gain controls so the fluctuating ambient noise registers equally on the Model E-2’s meters. Note that raising the preamp gain of one channel causes its gain to rise and the others to fall; it’s a balancing act. When balanced, all mics have equal access to the system gain. 6.
Dugan Model E-2 User Guide Stand-alone Operation If You Must Use a Pre-fader Insert The Dugan Speech System is more convenient to operate if patched post- rather than pre-fader. If your console allows this, skip this section. If you use a pre-fader insert, this section describes how to properly mute and pre-listen to muted channels. Muting Channels Mics must be muted by using the Dugan’s mute buttons. Pulling a fader down on the console will not properly mute a channel.
Dugan Model E-2 User Guide Pre-listening to Muted Channels If your console allows listening to a mic before the insert point, you can mute on the Dugan. If signal through the Dugan is required to pre-listen to a mic, pull the fader down and put the channel in bypass mode. When your mic check is done, switch the channel back to auto mode, and raise the fader so the Dugan can cue in the mic.
Dugan Model E-2 User Guide Chapter 5: Dugan Control Panel Software The Dugan Control Panel software has both Java and iPad versions. This chapter discusses the Java version and notes the iPad app’s few differences. NOTE: After configuring settings with the Dugan Control Panel, it can be disconnected. All settings are retained and the unit continues to function on its own.

Dugan Model E-2 User Guide Selecting Units to Display The Dugan Control Panel finds all available units connected to the network automatically. Some facilities have multiple studios on the same network that operate independently. In that case, you may want to restrict the units shown in the Top Pane to those in your studio. To do this: 1. Hover the mouse cursor over the names of the units that you want to display, and note their IP addresses. 2. Ctrl-click on the + sign at the right of the Top Pane.
Dugan Model E-2 User Guide Dugan Control Panel Software Naming Units and Channels Connected units are displayed in the top pane in alphabetical order. Use names with number prefixes if you wish to display them in your own order. To name a unit and its channels: 1. Select a unit in the top pane. 2. Select the yellow text in the right pane (under the Dugan logo) and type a name. 3. Press the Enter key on the keyboard to set the name. 4. To name a channel, select the yellow text and type a name. 5.
Dugan Model E-2 User Guide Level Indicator Each channel has a level LED that lights green when the audio level is adequate for automatic mixing. It should remain green when no one is talking. • If the level indicator blinks, raise the console’s channel input gain, and/or move the +4/-10 switch on the rear panel to -10. • If the level LED lights red, lower the console’s channel input gain and/or move the +4/-10 switch on the rear panel to +4 until it stays green at all times.
Dugan Model E-2 User Guide Dugan Control Panel Software Channel Modes There are three channel modes: man, auto, and mute. Changing modes initiates a half-second fade to the new mode. Like radio buttons, you can only choose one mode at a time. Figure 5-5 Channel modes Man In man mode there is no automixing, and the signal passes through at unity gain. Even though man and bypass modes perform similar functions, we recommend using man during live mixing to prevent clicks.
Dugan Model E-2 User Guide Preset Use the Preset function to store your favorite channel mode settings, which may be restored by pressing the Master PRESET button. When the unit powers up, the channels default to their preset modes. To set channel presets: 1. Click the channel preset button next to the desired channel mode button. 2. For all unused channels, click the preset button next to the mute button.
Dugan Model E-2 User Guide Dugan Control Panel Software Figure 5-7 Channels in three groups Override Override can be used to instantly mute all mics except one (the host or chairperson). However, any number of mics can be included in the override group. It can thus be used to make a dramatic A/B comparison between automatic and conventional mixing. To assign channels to an override group, activate the override button on each channel.
Dugan Model E-2 User Guide Weight Controls The weight controls set the side-chain levels for each channel into the control system. This establishes the relative sensitivity of the automatic mix for the channels in use. They do not change the mix levels. When the weight controls are balanced, each mic has an equal opportunity to take over the system: when one person talks into one mic, he/she gets all the auto mix gain and the others get turned down.
Dugan Model E-2 User Guide Dugan Control Panel Software Raising the weight control for one channel: • increases that channel’s auto mix gain display during ambience and decreases it slightly for the others; • makes it more difficult for others to speak when someone speaks into the channel with the higher weight setting.
Dugan Model E-2 User Guide Figure 5-10 shows eight- and four-mic systems with appropriate auto mix gain displays when no one is talking. Figure 5-10 Multiple mic ambience: auto mix gain hovers around -9 dB for eight mics, -6 dB for four mics Master Pane The content of the Master Pane changes to reflect the Dugan device selected.

Dugan Model E-2 User Guide Group Master Controls The Master Pane displays a set of group master control buttons for each group in use. Override Activating the Master OVERRIDE button has the following effect on individual channels: • Channel override button active: puts the channel in man mode with full gain (no automixing); - OR - • Channel override button inactive: mutes the channel. De-activating the Master OVERRIDE button returns the channels to normal operation.
Dugan Model E-2 User Guide Dugan Control Panel Software Dugan Music System and Gain Limiting These functions require the physical Model CP-2 or Dugan Control Panels for Java or iPad. Dugan Music System The Dugan Music System is a soft-gating or ducking system with its threshold set by an audio side-chain, typically from a mic measuring the ambient sound level. Each channel has a 2:1 expansion ratio below the floating threshold.
Dugan Model E-2 User Guide To set up the Music System: 1. Patch up to three reference mic signals (one for each group) for the Music System threshold inputs as described on page 21. 2. Click the arrow on the right edge of the Master Pane to open the Music System panel. Click to display the music system controls Click to close this panel Figure 5-13 Dugan Music System controls 3. Start with the three Master music system threshold controls set to 0 dB. 4.
Dugan Model E-2 User Guide Dugan Control Panel Software 9. Use the Master music system threshold settings to fine tune the master threshold for each group. There are several ways to enter values (see page 38). If all the channel auto mix gain displays stay at full gain, the threshold signal is missing or too low. 10.Fine tune individual channels using their thresh controls so the auto mix gain display stays close to -15 dB. iPad To close the Music System pane on an iPad, swipe it to the right.
Dugan Model E-2 User Guide Gain Limiting Gain Limiting reduces master gain as new mics enter the system, thus avoiding feedback and noise. Acoustic gain increases as each mic comes on, whether this occurs manually, by placing that channel in man mode, or automatically using the Music System. Gain Limiting is the only automatic mixing function that can be active when the channel is in man mode.
Dugan Model E-2 User Guide Dugan Control Panel Software The Dugan’s unique implementation allows you to set the number of mics at full gain before gain limiting occurs. Set the NOM gain limit field in the range 1–10 (see page 38 to learn how to set controls). For example, if there is enough gain before feedback to tolerate four open mics, set the NOM gain limit to 4. Gain reduction begins when the fifth mic turns on.
Dugan Model E-2 User Guide Gain Limiting and the Speech System The Speech System always maintains NOM = 1, which prevents Gain Limiting from sensing excess gain. Typically, the NOM controls have no effect when using the Speech System. However, the NOM function can help avoid feedback when • mics are switched to manual; - OR - • the Master OVERRIDE button is pressed with multiple mics selected. If either case applies, 1. Turn on NOM for all channels. 2. Set the NOM gain limit field to 1.
