Dugan Model E-2A User Guide Chapter 1: Introduction The Dugan Model E-2A Automatic Mixing Controller helps professional audio mixers handle multiple live mics without having to continually ride their individual faders. This signal processor can be patched into the input insert points of an audio mixing console. Then each mic channel is processed in the Dugan controller and returned to the console for mixing. Alternatively, internal mix buses in the Model E-2A can be used to sum channels.
Dugan Model E-2A User Guide Introduction The Model E-2A can: • process up to 28 channels (12 analog and 16 ADAT); • be remote controlled from the Dugan Control Panel for Java (included), Dugan Control Panel for iPad (sold separately), and the Dugan Model K Control Surface; • be directly controlled from its own front panel; • link with other Dugan automatic mixing controllers to create a larger system; • partition channels into one to three groups that can span linked units; • create separate sy
Dugan Model E-2A User Guide Chapter 2: Theory of the Speech and Music Systems 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 when using noise gates. The system automatically manages any number of live mics in unpredictable dialogue situations.

POINT Figure 2-2 Post-fader insert patching The Dugan Speech System is best patched post-EQ, post-fader, pre-compressor: • Post-EQ: Equalization can be applied to different mic types so they sound more alike, which benefits both the sound quality and the automixing process.
Dugan Model E-2A User Guide Theory of the Speech and Music Systems Dugan Music System Music System The Music System is a soft-gating ducking system with its threshold set by an audio signal, typically from a mic measuring the ambient sound level. Each channel has a 2:1 expansion ratio below the floating threshold. The Music System can also be used to duck an audience mix when the people on stage talk, attenuating the sound of the PA in the room.

Dugan Model E-2A User Guide Theory of the Speech and Music Systems Gain Limiting Gain Limiting is used along with the Music System—the Speech System doesn’t need it. It reduces master gain as new mics become active, 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 does not base its gain limiting calculation on the number of open mics.

Dugan Model E-2A User Guide Quickstart Chapter 3: Quickstart This section provides step-by-step instructions to help you get started quickly using the Dugan Speech System to mix up to 16 channels of analog I/O. If you need more than 16 channels of I/O or wish to use the Dugan Music System, skip this chapter. In this Quickstart you will: • Execute a system reset. • Set the audio interface to AES using the back panel switch. • Patch inserts to the console. • Set console input gains.
Dugan Model E-2A User Guide Quickstart Audio Connections Move the ANA–DIGI switch on the back panel to the ANA (up) position. The DB-25 connectors (wired with the TASCAM digital convention) are used for analog I/O. Since mixers use a variety of I/O connectors, you must obtain a DB-25 digital breakout adapter cable to connect to the console, or wire a DB-25 connector to your patchbay. Figure 3-1 Model E-2A back panel NOTE: To wire unbalanced inputs, connect both Gnd and Lo pins to the source ground.
Dugan Model E-2A User Guide Quickstart Figure 3-2 insert patch for the Dugan Speech System on a Yamaha digital mixer. Setting Console Input Gains Dugan automixers require enough console preamp gain so the algorithm can measure the ambient noise level on each channel. To set the console gain level: 1. Navigate up to MENU and press ENTER. 2. Use the navigation arrows to select Channel View and press ENTER.
Dugan Model E-2A User Guide Quickstart level LED Figure 3-4 Eight Channels screen 5. When no one is talking, set each console preamp so there is enough gain in each channel so the level LED at the top of the Dugan front panel display stays on and all meters float at about the same gain. This procedure assures smooth automatic mixing. To display additional channels, navigate down to select the double arrows and turn the knob.
Dugan Model E-2A User Guide Chapter 4: Installation Rack Mounting One or two half-rack-sized Dugan controllers can be mounted in a single rack space. Each unit ships with one long and one short rack ear and one joining plate. Two units provide the necessary parts for mounting side-by-side. The rack ears for older half-rack Dugans differ slightly from the current design, but the joining plates are the same.
Dugan Model E-2A User Guide Installation The Model E-2A provides the following connectors: • AUDIO 1–4, AUDIO 5–8, AUDIO 9–12 These three DB-25 connectors each carry four balanced I/O channels, and are wired with the TASCAM digital pinout (see Appendix A: Connector Pinouts). When the unit is powered off, bypass relays connect all input channels to their respective output channels. This lets you turn off the unit while allowing audio throughput without unpatching.
Dugan Model E-2A User Guide Installation Model E-2A Modes The Model E-2A has an ANA/DIGI mode switch that controls whether to use analog or ADAT as your primary I/O. When set to analog mode however, the analog and ADAT channels can operate simultaneously. This can yield up to 28 automix channels. In ADAT mode, analog channels will not appear in the Dugan Control Panel. NOTE: Unprocessed splits of the input signals are always present on the outputs of the unused I/O connectors.

Dugan Model E-2A User Guide Chapter 6: Dugan Control Panel Software The Dugan Control Panel software has both Java and iPad versions. This chapter discusses the Java version. The few differences in the iPad app are noted. NOTE: After configuring the unit with the Dugan Control Panel, it can be disconnected if you do not wish to use it. All settings are retained, except on power up the Preset function is invoked (see page 41). Figure 6-1 Dugan Control Panel Launch the Dugan-Control-Panel-vxxx.jar.
Dugan Model E-2A User Guide Dugan Control Panel Software The Dugan Control Panel has three panes. The controls displayed in these panes depend on which Dugan device is selected in the Top Pane. Top Pane Icons for all connected Dugan units Channel Pane Controls for individual channels Master Pane Controls for groups a, b, and c Top Pane The Top Pane displays all connected Dugan units. The selected block is enclosed by a yellow rectangle. These channels are shown in the Channel Pane.
Dugan Model E-2A User Guide Dugan Control Panel Software Adding Units Manually To add a unit with a known IP address manually, click the + sign at the right of the Top Pane and enter the IP address in the dialog that appears. To display a unit’s IP address, hover the mouse over the unit’s name. Setting Controls Controls can be adjusted five ways: • Enter a dB value in the numeric field. • Drag in the numeric field (not on iPad). When a slider is present: • Drag the slider up or down.
Dugan Model E-2A User Guide Dugan Control Panel Software Channel Pane The Channel Pane contains all channels in the selected block of the Top Pane (highlighted with the yellow rectangle). If your screen is wider, you can display more channels by stretching from the right margin. Otherwise, you can use the scroll bar at the bottom to see additional channels, or select a different block in the Top Pane. Channels are either in bypass or one of three operating modes: man, auto, or mute.
Dugan Model E-2A User Guide Dugan Control Panel Software 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 console’s +4/-10 switch on the back panel to -10. If the channel input gain is already set to its maximum, raise all the weight controls an equal amount (e.g., from 0 to +5).
Dugan Model E-2A 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 6-5 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-2A User Guide Dugan Control Panel Software 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-2A User Guide Dugan Control Panel Software Channel Groups Each channel can be assigned to one group: a, b, or c. Each group functions as a separate, independent automatic mixer that can span multiple linked Dugans. Channels assigned to groups need not be contiguous. Applications where groups are helpful include: • Separate Rooms: Assign the mics in each room to different groups so they function as separate automatic mixers.
Dugan Model E-2A User Guide Dugan Control Panel Software Meters The meters have three display modes. The default mode is auto mix gain, which is the most useful display during normal operation. The input and output meters are only used when setting or checking levels.
Dugan Model E-2A User Guide Dugan Control Panel Software It is important to understand that weight does not set that mic’s level in the mix when that person speaks, but only its sensitivity in activating automatic mixing. The Speech System detects the ratios of the levels between channels, not their absolute levels. The weight control is not a gate threshold! The following example illustrates how weight affects auto mix gain (see Figure 6-9).
Dugan Model E-2A User Guide Dugan Control Panel Software Figure 6-10 shows eight- and four-mic systems with appropriate auto mix gain displays when no one is talking. Figure 6-10 Multiple mic ambience: auto mix gain hovers around -9 dB for eight mics, -6 dB for four mics You can perform the following functions using the weight controls: • If there is ongoing noise near one mic (e.g., computer fan or air vent), suppress it by reducing that channel’s weight.
Dugan Model E-2A User Guide Dugan Control Panel Software Master Pane The content of the Master Pane changes to reflect the Dugan device selected. In the figure below, the selected device is a Model E-2A.

Dugan Model E-2A User Guide Chapter 7: Pre-fader Insert The Dugan Speech System works either pre- or post-fader, but it is more convenient to operate post-fader. If your console allows a post-fader insert, skip this chapter. Workaround to Create Post-fader Insert If your console has post-fader direct outputs and enough extra inputs, you can create post-fader inserts (see figure below).
Dugan Model E-2A User Guide Pre-fader Insert To properly mute a channel with the console faders up, adjust levels while people are talking. Mute a mic by clicking the channel mute button on the Dugan Control Panel. Enable the mic by activating the auto button. Muting mics does not alter the overall ambient sound mix: the Speech System raises the ambient gains of the other mics to compensate for the gain subtracted by muting a mic. This occurs during ambience without input to any mic.
Dugan Model E-2A User Guide Chapter 8: Dugan Music System and Gain Limiting Dugan Gain Limiting is typically used with the Dugan Music System. To learn more about these concepts, see Chapter 2: Theory of the Speech and Music Systems. Dugan Music System The Dugan Music System is a ducker with its threshold set by the level of an audio side chain (the Music System Threshold Input). Each channel has a 2:1 expansion ratio below the floating threshold.
Dugan Model E-2A User Guide Dugan Music System and Gain Limiting Meter The meter can show the Music System Threshold Input level or the amount of NOM Gain Limiting. Clicking the title button toggles between them. NOM Gain Limit This field controls the NOM (Number-of-Open-Mics) Gain Limit. Enter a new value from 1 to 10 (default = 1). Music System Threshold Input Channel For each Group, click the music thresh input ch.
Dugan Model E-2A User Guide Dugan Music System and Gain Limiting Using a Sensing Mic Consider the following before placing a sensing mic: • Use the same type of mic for program and sensing applications. • Place the sensing mic in the same area, and pointing in the same direction as the program mics. This samples, as closely as possible, the ambient sound picked up by the program mics. • Do not place the sensing mic close to an individual voice or instrument.
Dugan Model E-2A User Guide Dugan Music System and Gain Limiting Completing Setup of the Music System To continue setting up the Music System (sensing mic or submix): 1. On the Dugan’s Channel Pane, activate the music button on the desired channels. The music tab will appear on the Master Pane when at least one channel is assigned to the Music System. 2. Click the music tab on the right margin of the Master Pane to open the Music System panel.
Dugan Model E-2A User Guide Dugan Music System and Gain Limiting Controlling Ambience Unlike the Speech System, the Music System does not maintain constant ambience. If you need to smooth out the ambience, two methods can be used separately or together: • The last hold function keeps the last mic used at full gain. The last hold is activated when a channel’s automix gain stays above -3 dB for 0.5 seconds. When another mic passes the same criteria, it becomes the last hold mic.
Dugan Model E-2A User Guide Dugan Music System and Gain Limiting Gain Limiting and the Speech System The Speech System always maintains NOM = 1, which makes Gain Limiting unnecessary. 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.
