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.
The Model E-2 tracks unscripted dialogue, eliminating cueing mistakes and late fadeups, while avoiding the choppy and distracting effects common to noise gates.
The Model E-2 supports a broad spectrum of live mixing applications:
•
Conference reinforcement, video trucks
•
Houses of worship
•
TV news and sports panels, reality and game shows
•
Wireless mics for theater
•
Boardrooms and civic meeting rooms
•
Teleconferencing and distance learning
The Model E-2 dramatically improves live mixing with multiple mics by:
•
eliminating late upcuts;
•
reducing PA feedback and studio noise;
•
reducing comb filtering from adjacent mics.
The Model E-2 can:
•
be physically controlled from its own front panel, or the Model CP-2 Control Panel
(sold separately);
•
be remote controlled from the Dugan Control Panel for Java (included) and Dugan
Control Panel for iPad (sold separately);
•
conveniently connect multiple devices via four network ports;
•
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 linked systems that do not interact (i.e., for separate studios).

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.
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 1-1 Four snapshots of a three-mic system
Figure 1-1 shows the Speech System in action with a three-mic system.
•
The first frame shows 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.
•
The second frame shows one person speaking. The system automatically fades his/
her gain to full, while the other two inputs are turned down.
•
The third frame shows a different person speaking. The system automatically
fades his/her gain to full, while the other two inputs are turned down.
•
The fourth frame shows two people speaking simultaneously. The system automatically shares the gain between them, while the other input is turned down.

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. Each
channel has a 2:1 expansion ratio below the floating threshold. There are three Music
System Threshold inputs on the AUDIO I/O 9–12 connector (channels 9–11), one for each
group.
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. Use an aux send of the stage
vocal mix to supply the threshold signal instead of a mic.
The following example (Figure 1-2) shows how the Music System works with three
background vocalists.
•
Frame 1 shows no one singing. The system keeps all channels at a low gain.
•
Frame 2 shows one person singing. The system automatically fades his/her gain to
full, while the other two inputs stay low.
Figure 1-2 Function of the Dugan Music System
•
Frame 3 shows a different person singing. The system automatically fades his/her gain
to full, while the previous singer’s mic and the other input stay low.
•
Frame 4 shows two people singing together. The system automatically gives their
channels full gain, while the other input stays low.

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.
Conventional automatic mixing implementations always assume an NOM of 1.

The Dugan’s unique implementation allows you to set the number of mics at full
gain before gain limiting occurs.
For example, if there is enough gain before feedback to tolerate four open mics, the
gain limit can be set to 4. Gain reduction begins when the fifth mic turns on.

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.
•
The Dugan Music System™ offers automatic downward expansion to help reduce
feedback and bleed in live music performances (i.e., opera, background vocals).
Thresholds are adjusted automatically by monitoring ambient noise levels.
•
Dugan Gain Limiting™ monitors the number-of-open-mics (NOM) and adjusts
the master gain to prevent feedback or ambient noise build-up. Dugan Gain
Limiting should be used with the Dugan Music System to reduce feedback and
noise. It can perform the same functions when mics are switched on and off
manually.
•
Linking creates one large automatic mixing system with multiple Dugan units.
•
An internal mix bus matrix routes processed or unprocessed inputs to four mix
bus outputs.
•
Unprocessed outputs are provided: analog inputs are mirrored at the digital output, and vice versa. This provides convenient pre-processing signals for multitrack
recording.
Twelve-channel
•
The Dugan Speech System™ provides automatic mixing for twelve live mics.
•
Linking creates one large automatic mixing system with multiple Dugan units.
Sixteen-channel
•
The Dugan Speech System™ provides automatic mixing for sixteen live mics.
This is a digital connection that uses both the AUD and LINK ADAT optical connectors.

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. Keep holding the
bypass button down for three seconds until the unit finishes booting.
This System Reset command sets all parameters to factory default settings and
clears label text.
We recommend executing a System Reset before starting a new installation. This
is just like zeroing a console before a show.
3. Set the NORM-SLAVE switch on the rear panel to NORM (up) for unlinked operation.
The Model E-2 can be interfaced using balanced analog or digital optical connectors:
4. Analog: Move the ANA-DIGI switch on the rear panel to the ANA (up) position.
The DB25 connectors carry balanced analog signals. Each connector provides four
inputs and four outputs.
Figure 2-1 Model E-2 rear panel
Digital: Move the ANA-DIGI switch on the rear panel to the DIGI (down) position,
connect the console ADAT output to AUD IN, and connect AUD OUT to the console’s
ADAT input.
5. Whenever possible, route each Model E-2 channel as a post-fader, pre-compressor
insert to each mic channel.

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.
NOTE:
When the green level light extinguishes, the channel is in a downward expansion mode
to avoid feedback. This condition should be avoided because the smooth ambience that
characterizes Dugan automatic mic mixing is lost.
Figure 2-3 During ambience with 4 mics, auto mix gain displays should hover around -6 dB
7. Adjust your console’s preamp gains so all LED meters float at about the same gain
when no one is talking. This procedure assures smooth automatic mixing.

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.
The rack ears for older E-Series Dugans differ slightly from the current design, but the
joining plates are the same. All E-Series Dugans can be mounted side-by-side using
the appropriate rack ear for each unit.
To mount one unit: Attach one long and one short rack ear, then mount in the rack.
To mount two units side-by-side:
1. For the left unit, remove the four screws from the right side of the top and bottom
lids.
2. Attach the top and bottom joining plates to the left unit.
3. For the right unit, remove the four screws from the left side of the top and bottom
lids.
4. Attach the top and bottom joining plates to the right unit.
5. Attach the appropriate rack ears to the left and right units.
6. Mount the pair in the rack.

Music System Threshold Inputs
A Music System threshold signal can be provided as a reference for each group. When
the levels of channels in the group exceed the level of the Music System threshold
signal, the channels come up to full gain.
The sensing mics are typically input to the same console as the program mics, but are
routed to direct outputs or sends, not mix buses.
The AUDIO I/O 9–12 DB25 connector can receive three Music System threshold inputs,
one for each group (a, b, c on channels 9, 10, 11).

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. Designate any other units as slaves by setting their NORM–SLAVE switches on the
rear panel to SLAVE (down).
3. Use ADAT (Toslink) cables to link units in a ring network (see above).
Note that all LINK IN and OUT connectors are used to create the ring.

Connecting to a Computer
Two Java applets are provided with the Model E-2:
•
The Dugan Utility helps you connect to a network.
It is also used to update the firmware (see Chapter 6: Updates).
•
The Dugan Control Panel offers expanded operational capabilities.
Insert the USB thumb drive (or CD) supplied with the Model E-2, or download the
latest version from:
http://www.dandugan.com/downloads
- OR http://tech.groups.yahoo.com/group/duganusers/files/
To connect the Model E-2 directly to a computer, use the rear panel Ethernet jack.
An older PC may require a crossover cable.
Use a straight Ethernet cable to connect to a network.
We strongly recommend that Windows users turn the Windows firewall off. The
Windows Firewall blocks port 9776 used by the Dugan software to communicate. If
you must leave the Windows firewall on, either open this port or use the workaround
described in Connecting when Windows Firewall is On on page 29.
We recommend turning off the computer’s WiFi during this process because it sometimes interferes. You can turn it back on after the connection has been established.

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. Using a normal speaking voice, adjust the console input trim controls to the highest
possible gain without clipping.
The input gain to the Model E-2 should be high enough keep the level LED lit
green during silences. If the input trim controls do not provide enough level, set
the +4/-10 switch to the -10 position.
If the preamp gain controls are set too low, the inputs drop below their minimum
operating level. This causes downward expansion to prevent feedback but the
smooth ambience is disrupted.

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. If clipping occurs because someone speaks louder than expected, turn down all of
the console’s input trim controls the same amount, and raise the console master
to compensate.
This procedure maintains the ambient noise balance required for optimal automatic mixing. A better method uses the weight controls provided by the Model
CP-2 or Dugan Control Panels for Java or iPad. See Chapter 5: Dugan Control Panel
Software.
Figure 4-3 During ambience with 4 mics, auto mix gain displays should hover around -6 dB
Figure 4-4 During ambience with 8 mics, auto mix gain displays should hover around -9 dB
TIP:
To eliminate an unwanted noise in the mix, use the gain displays to locate the offending
channel and activate its mute button.

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. Although that mic is no longer audible in
the mix, it still contributes to the gain computations and causes ambient noise fluctuation. In the worst case, this could cut off a speaker.

To properly mute a channel:
•
Leave the console faders up, adjust levels while people are talking, and mute a mic
by pressing the Dugan’s mute mode button. Enable the mic when needed by deactivating the mute button.
Muting mics does not alter the overall ambient sound mix: the Speech System compensates by slightly raising the ambient gains of the other mics to compensate for
the gain subtracted by muting a mic. Note that this behavior is during ambience
without input to any mic; while one or more mics receive speech input, the gain
shifts to the active mics.
- OR -
•
Use the bypass switch with the console fader pulled down. This keeps the mic instantly available on the fader but that channel is no longer in the control mix.
Be aware that bypass may generate a click if it interrupts room rumble, whereas
the mute button does a quick-fade. The mute button can be used with the fader up;
bypass is best used with the fader down.
33
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.

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. Press the Enter key on the keyboard to set the name.
Channel naming is cleared by pressing reset (see page 48).
Channel Pane
The Channel Pane contains the controls and indicators for each channel. Channels
are always in one of three modes: man, auto, or mute. The active channel mode illuminates. All transitions are made with a smooth, rapid fade. Select a channel mode
by pressing the individual mode buttons or the Master PRESET button.
Figure 5-3 shows a typical system: channels 1–4 in auto with ambient noise, and channels 5–8 in mute.
Figure 5-3 Channel Pane
39
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.
Bypass
When bypass is active, the signal passes through without A/D and D/A conversion or
automixing. A bypassed channel appears inactive, with all lights extinguished.
Figure 5-4 bypass button lit
Man and bypass modes are similar:
•
bypass makes an instantaneous transition, which can cause an audible click. It is
a hardware bypass and therefore has no signal latency.
•
man performs a quick fade without sonic artifacts. It has the same signal latency
as auto mode.
Since analog channels 1–12 are bypassed when the power is off, it is not necessary to
unpatch the Model E-2 if not in use.
To deactivate bypass, you can:
•
Click bypass again;
- OR -
•
Click any of the three channel mode buttons.

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.
Auto
This is the normal Dugan automixing mode.
Mute
The channel is muted when mute is active.

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.
•
Stereo Panning: Assign the mics panned left, right, and center to groups a, b, and
c, respectively, to maintain a stable stereo ambience.
To assign a channel to a group, click the group button until the desired group letter
appears. The channel strip background is tinted green (group b) or blue (group c); group
a is not tinted (Figure 5-7). A set of OVERRIDE, PRESET, and MUTE buttons appears in the
Master Pane for each group.

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.
Pressing the Master section OVERRIDE button puts channels with their override buttons
lit into man mode. All other channels are muted. Press the OVERRIDE button again to

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.
Figure 5-8 Weight controls
The weight controls should be used to balance the channel auto mix gain indicators
when no one is talking. If a console preamp trimmer is turned down, that channel’s
weight control can be turned up to re-balance the automixing, and vice-versa.
To adjust the weight setting, click and drag the weight slider or enter a number in the
numeric field. Ctrl-click the weight slider to reset it to 0.
iPad
Touch and hold the weight slider to reset its value to 0.
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 5-9).
44
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.

Lowering the weight control for one channel:
•
decreases the auto mix gain display during ambience for that channel and increases
it slightly for the others;
•
makes it more difficult for that channel’s talker to be heard over the others.
For optimal performance, balance the weight controls so the channel gains display approximately equally when no one is talking. If there is ongoing noise near one mic
(e.g., computer fan or air vent), suppress it by reducing that channel’s weight. Of
course, you will hear that noise increase when that talker speaks.

System
When multiple Dugan units are linked, groups a, b, and c can span linked units.
Groups operate as independent automatic mixers, and do not have to use contiguous
channels.
It is possible to have multiple systems of linked units on your network (i.e., separate
studios on the same network). These units will all appear in the top pane. The Model
E-2 allows up to 16 separate systems on a network.
To separate multiple systems:
1. Select the first unit to include in the system by clicking it in the top pane.
2. Click the system button and select a unique number for that system.
3. Repeat for each unit in that physically linked system, making sure to use the same
number for each unit in the system.
4. Repeat steps 1–3 for each system.
5. To query which system a unit belongs to, select it in the Top Pane and view its

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. There are three Music
System Threshold inputs on the AUDIO I/O 9–12 connector (channels 9–11), one for each
group.
Consider the following before placing the sensing mic:
•
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.
•
Use the same type of mic for program and sensing applications.
•
Do not place the sensing mic close to an individual voice or instrument.
•
Do not point the sensing mic at a pit orchestra.
•
Do not put the sensing mic in the back of the house because of the time delay.
Patch the preamplified sensing mic to input 9, 10, or 11 (group a, b, or c) on the AUDIO
I/O 9–12 connector. The direct output of a console input strip is typically used, with the
mix buses deselected. Set the console input gain for the sensing mic 10–15 dB higher
than the program mics.
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. Use an aux send of the stage
vocal mix to supply the threshold signal instead of a mic.
Setting up the Music System
Some channels can be set to the Music System while others are in the Speech System.
Unlike the Speech System, the Music System channels should be patched post-EQ,
pre-fader so that fader and threshold adjustments remain independent.
51

Controlling Ambience
The Music System does not maintain constant ambience like the Speech System.
If you want to smooth out the ambience:
1. Click the arrow on the right edge of the Master Pane of the Dugan Control Panel
to display the Music System controls.
2. Reduce the maximum attenuation by setting the auto mix depth field to -10 dB.
This limits the range of downward expansion and mixes in a steady ambience.
If you use the Model CP-2 Control Panel, the last hold function is available: press
both the Master OVERRIDE and PRESET buttons at once. Their LEDs blink to indicate that last hold is on; toggle it off the same way. The last hold function keeps
the last mic on that stays above -3 dB gain for 0.5 seconds. When another mic
passes the same criteria, it becomes the last hold mic.
NOTE:
iPad
The Music and Speech Systems operate independently, but the auto mix depth control is
global to both. Use different groups if necessary.

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. Gain Limiting is controlled by the NOM (Numberof-Open-Mics) channel buttons and the master NOM gain limit field (see Figure 5-13).
NOTE:
Since the Model E-2 has no master audio channel, Gain Limiting reduces the gain on all
input channels for which NOM is active.
Unlike typical NOM functions on other systems, Dugan Gain Limiting doesn’t just
count how many mics are on. It sums the instantaneous gains of all the channels
with NOM active (including partially attenuated channels), compares them to the NOM
gain limit threshold, and reduces the gain appropriately. Gain Limiting works independently for each group.
Conventional automatic mixing implementations always assume an NOM of 1. This
can be effected on the Dugan by setting the NOM gain limit field to 1, which maximizes
gain for each mic. Activate the NOM buttons for each channel you wish to be included
in the gain computation. The Master Gain Limiting display shows 3 dB of gain reduction when two mics are on, 6 dB of reduction with four mics on, etc.

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.

6. Switch additional channels to man mode to see more attenuation.
7. Click and drag in the NOM gain limit field to set it to a higher number than 1.
Note the difference in the NOM gain limiting display.
Previewing Mics
To preview mics on the console when Gain Limiting is active, we recommend using
the bypass switch with the fader down to pass signal through the Dugan. This sends
the signal through without the gain limiter affecting other channels.
55
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.
If channels are set to both Speech and Music Systems, you can choose whether they
should interact. If you do not want the master gain reduction of the Music System
mics to affect those in the Speech System, turn the NOM buttons off for the Speech

Chapter 6: Updates
Updates for the Model E-2 can be downloaded.
iPad
To update the firmware in your Dugan unit, iPad users must connect the Dugan to a computer
and run the Dugan Utility.
To update the Dugan Control Panel for iPad, connect to the Apple App Store.
To update your device’s software and firmware:
1. Connect to the Internet and download Dugan-Software-yyyymmdd.zip from:
http://www.dandugan.com/downloads/
- OR http://tech.groups.yahoo.com/group/duganusers/files/
After the download is complete, the Internet connection is no longer necessary.
2. Unzip the software package.
It contains the Dugan-Control-Panel-vxxx.jar and Dugan-Utility-yyyymmdd.jar. The Dugan Utility contains the latest versions of both the firmware and
the safety copy of the Dugan Control Panel that loads automatically into the unit.
To revert to a previous version, use the older version of the Dugan Utility.
3. Connect the computer to the Dugan units you wish to update.
4. Launch Dugan-Utility-yyyymmdd.jar.
The Dugan Utility window appears.

Appendix A: Power-up Commands
The Model E-2 can execute five power-up commands that can choose essential settings without being connected to a computer or iPad.
Select the command by holding down a specific button during the entire power-up
process (see table below). Power-up is complete after the LEDs stop flashing.
To execute more than one command, turn the unit off after it finishes powering up,
and repeat for the next command.
