Introduction
Do you want to control a ProDX™mixer via your
Android or iOS device? Of course you do! Well, you’ve
come to the right place! After all, the MixerConnect™
app is designed to be used in conjunction with ProDX.
At this point, you must be well-versed in – or at least
somewhat familiar with – the ins and outs of ProDX.
More information may be found by visiting the ProDX
Owner’s Manual.
MixerConnect is great for mobile freedom to control
everything from levels and EQ to linking channels
to tools like FX and compression for amazing sound
in any situation.
MixerConnect allows control of ProDX mixers
via Bluetooth with...
• Compatible Android devices running version 4.1
or higher.
• Compatible iOS devices running iOS 8.0 or higher.
You should be able to stream audio from
any Bluetooth-paired device. However,
the MixerConnect app is needed to mix
audio, including wireless adjustments
of level, EQ, FX and more.
The MixerConnect app does not mix audio
on its own. It requires a ProDX mixer to
fully function.
MixerConnect V1.0
This version of the Reference Guide is written
and designed for MixerConnect V1.0. With each
software update, some screen shots may look slightly
different than what you see within these pages and
there could be some functional differences, as well.
About This Guide
The entire guide does not need to be read to figure
out how to use the MixerConnect app. However,
a certain amount of familiarity with ProDX and its
features is assumed.
As the saying goes, “a picture is worth a 1000 words”.
With that thought in mind, we added quite a few
illustrations, screen shots and other images throughout
to accompany the text.
This icon marks information that
is critically important or unique!
For your own good, read and remember
them.
There’s an illustration of a microscope, so,
of course, you’re going to get more detailed
information when you see this little guy.
There are explanations of features and
practical tips listed here.
It’s a good idea to pay attention to text
displayed next to a note icon, as this
icon draws attention to certain features
and functions relating to the usage of
the MixerConnect app.
Things to Remember:
• Never listen to loud music for prolonged periods.
• Life is short. Be cool.
Getting Started
There are a few steps to accomplish before messin’
around with the MixerConnect app. For starters,
we’ll take a look at how to download, install and
update the app. Next, we’ll pair the device with
the mixer via Bluetooth. The last step is setting levels.

Part II: Pairing and Connecting the Android Device
via Bluetooth
You should have to follow these
instructions only once for each device
paired via Bluetooth. After that they
should remain paired, although you will
need to connect manually to the ProDX. If already
paired, follow steps 6-8 to connect manually to the
ProDX.
These are the steps necessary to pair the device with
the ProDX unit.
1. Start by turning both the device and the ProDX
on (if they’re not already).
2. Tap the ‘Tools’ icon to open the device’s settings.
3. Tap anywhere on the Bluetooth line to open it.
4. From here, enable Bluetooth simply by swiping
right. [Tapping also enables / disables Bluetooth].
5. To enter pairing mode, press and hold
the BT / Line In button on the front panel
of the ProDX.
The button LED will illuminate and flash
white while in pairing mode. If it does not,
start the pairing process again, and make
sure that ProDX and your device are both in pairing
mode at the same time.
6. As seen below, ProDX is listed as a device, but is
not connected.
7. Since we’re trying to connect ProDX via Bluetooth,
tap it.
8. From there, your device should indicate
that it is successfully paired and connected.
9. Now simply return to the home screen on the

7. This then turns into a green INSTALL button.
To install the MixerConnect app to a device, tap
the green INSTALL button and enter your Apple ID
password when prompted. The button turns into
a circle, indicating that MixerConnect is downloading
to the device.
As seen in the screen shot below left, the
MixerConnect app icon shows the progress
of the download.
The download is complete once the entire app is
illuminated. The MixerConnect app is now ready
for use.
8. It is possible that the MixerConnect app has
already been downloaded and installed. In this case,
you’re probably good to go. However, it is a good idea to
go to the App Store to check for updates. You will want
the latest and greatest version for the absolute best in
functionality and versatility.
Once in the App Store, tap the Update button located
near the bottom-right of the device.
The first screen shot below shows a device with all
apps up to date. The second screen shot below displays
two apps that need updating (which may or may not
include the MixerConnect app). Tapping the Update
button here will horizontally display the icon, name and
description of changes of each app needing an update.
If you see MixerConnect listed, tap the blue UPDATE
button on the far right, followed by typing in your
password. Or better yet, tap the blue Update All button
in the upper-right corner of the screen. The updates will
commence. Don’t do anything until the downloads have
completed.

MixerConnect
Additional Bluetooth notes [Android and iOS]:
If the device had been previously connected
to ProDX via Bluetooth, but it displays
“Not Connected”, it’s quite possible that
either the ProDX is not powered on or
it needs to be manually reconnected (as described
in steps 6-8).
The Bluetooth fader / volume control of
the MixerConnect app is not the same
as the OS / hardware Bluetooth level control,
but rather a supplementary level control. In other
words, the volume of the Bluetooth on the device need
to be up in order to hear audio over Bluetooth. If this
does not make sense, please refer to Appendix D:
Optimizations for step-by-step instructions.
The Bluetooth may disconnect when
affected by Electrostatic Discharge [ESD]
or electrical fast transients (EFT). If this
occurs, manually reconnect the Bluetooth connection.
A Bluetooth connection and 1/8" line-level
connection may NOT be used simultaneously.
If there is a physical connection to the
stereo input, it will take priority over any Bluetooth
connection. For example, if you are playing a song
from a smart phone (connected via Bluetooth)
and connect an MP3 player to the 1/8" jack, the smart
phone song will be interrupted and the MP3 player
now takes precedence.
Part III: Level Setting Procedure
These instructions may be found on page 4 of the
ProDX Owner’s Manual, but are listed again below:
The following steps will help you set up ProDX
quickly.
These startup instructions are intended for
the hardware only. Once proven that ProDX
performs as desired, then pair it with a smart
phone and control it via the MixerConnect
app.
1. Make all initial connections with the power switch
OFF.
2. Connect cords from the main outs to powered
speakers (or to an amplifier connected to passive
speakers).
3. Plug signal sources into the ProDX’s Wide-Z™
combo inputs – 1/4" and XLR! – such as:
• Microphones plugged into the mic inputs.
• Instrument level sources, such as acoustic
guitars w/ active pickups and line-level sources
such as keyboards and drum machines plugged
into the 1/4" inputs.
• Music playback source such as a smart phone,
computer or MP3 player plugged into the 1/8"
input or smart phone paired and connected
via Bluetooth.
4. Push the power supply connector securely into
the mixer’s connector and plug the other end into
an AC outlet.
5. Turn the ProDX on.
6. Turn the powered speakers (or amplifiers) on.
7. Be sure that the volume of the input is set
correctly. Select the input channel by pressing
the corresponding channel button and ensure
the level is about halfway. Adjust the rotary knob
if you need a different level for your source.
8. Slowly bring up the main output level to a
comfortable listening level by selecting the main
output on the front panel and slowly turning the
encoder to the right.
9. Read the rest of this reference guide and
the ProDX Owner’s Manual for more details!

MixerConnect – Three Main Views
From here on out, operation is virtually identical
between Android and iOS although some of the views
will differ slightly whether you are operating a ProDX4
or ProDX8.
In addition to the opening Welcome view, there are
three main views in the MixerConnect app:
• Mixer View
• Channel View
• System View
This page outlines what may be accomplished with
each of these three views. Soon enough we will go
through each of these in detail.
Mixer View
As seen in the image below, the Mixer View allows
access to key controls such as levels, metering, mutes
and more. From here you’re able to one-touch navigate
to the...
• Channel View / Graphic EQ

Introduction
As mentioned earlier, the Mixer View allows access to
key controls such as levels, metering, mutes and more.
1. Mute
Mute buttons do just what they sound like they do.
They mute – turn off – the signal on the channel(s).
Engaging a channel’s mute switch provides the same
results as sliding the channel fader all the way down.
Muting a channel mutes it on ALL outputs.
Mute buttons illuminate red when engaged and are
gray when disengaged.
2. Gain Reduction Meter
It may seem like we placed an ellipsis underneath
each channel’s Mute button, but no no... these three
dots display the input channel gain reduction from the
compressor. These yellow LEDs illuminate from right to
left. The amount of gain reduction of each LED is listed
below:
Compressor engaged
More than 6 dB of gain reduction
More than 12 dB of gain reduction
The compressor level is raised or lowered in the
channel view [see page 17].
If your compressor looks similar to this,
you might actually be driving and not
mixing. Put the phone down and drive!
3. Channel Name
The input and output channels are labeled between
the compressor levels and faders and meters. These
labels display the fader value as the fader level
is adjusted; in this case, +3 dB on the main mix.
The FX channel will display the actively selected
FX type; in this case, “Reverb”.
4. Channel Faders and Input Meters
The touch sensitive faders adjust the level
of each channel going to the selected mix [#9,
pages 12-13]. Adjustments are made by touch-
ing and dragging channel faders up and down.
Touched channel faders will “grow & glow” to
indicate that they are being adjusted. The fader
level ranges from –∞to +12 dB.
The input meters display the input signal level
to the channel before all channel processing.
Changes made to the EQ, mute and fader do not
affect these meters. In normal use, this meter
should remain green with the occasional bump
into the yellow zone.
Lower the volume of the source if the input meter
remains consistently yellow. If the input is too high
[overloading], a clip indicator at the top of the meter
will illuminate red. If clipping occurs, lower the volume
of the source a little more.
You may notice latency with the metering.
This is due to the limitations of Bluetooth,
not ProDX.

5. EQ / FX Channel View
The buttons located at the bottom of channels
1 and 2 (and 3 through 6 on the ProDX8) and
the Bluetooth / Stereo channel strip allow access
to the selected channel’s Channel View.
When tapped, the entire selected channel strip
slides to the left and the selected output strip – main
or aux –remains on the right. The middle then becomes
occupied with the selected channel’s EQ section,
FX send level, compressor level and an option to
link the adjoining channel. See pages 14-18.
The sliders on the EQ / FX button lie horizontally
in mixer view and vertically in channel view indicating
where they will take you. Simply tapping this button
again returns you to the mixer view.
6. FX Return
The FX return strip looks and works nearly identical
to that of an input channel strip. The only differences
are: (1) this fader adjusts the output level of the FX,
(2) instead of an EQ or gear icon button at the bottom
of the strip, there is an FX button and (3) there is no
compressor. This is detailed next.

7. FX Channel Button
The button located at the bottom of the FX return
channel strip allows access to the FX channel view
for FX selection.
When tapped, the entire FX return channel strip
slides to the left and the selected output strip – main
or aux –remains on the right. The middle then becomes
occupied with the 16 FX from which to select. See page
17.
As seen below, the FX button in mixer view [sound
wave icon] and channel view [vertical sliders] differs.
Simply tapping this button again returns you to the
mixer view.
8. Main / Aux Mix
The main mix strip looks and works nearly identical
to that of an input channel strip. The only differences
are that (1) this mute button mutes the selected output
(Main or Aux) and (2) this fader adjusts the main
output level of the selected output (Main or Aux).
So you’ve stated “... the selected output (Main
or Aux)” a few times now now. What exactly does
that mean? Excellent question...that’s discussed next!
9. Mix Selector
The mixer view shows a fader for each channel.
Initially, this fader controls the level to the main mix.
But how do you control the level going to the aux sends?
Or how about the aux master level? Simple. Use the mix
selector to switch between mixes.
The currently selected mix is illuminated, but
changing the selected output is easy. Simply tap the
desired output – Main, Aux 1 or Aux 2 [ProDX8 only]
and voilà...MixerConnect now controls a different
output.
Once a different mix has been selected, the color
surrounding the channel faders will change to show
the newly selected output. Similarly, the main fader
will display the newly selected mix. Here, the mixer
view acts like a window where you may view and
change one output’s mix at a time. No matter which
output is currently selected, the others are still there,
as they were.
Navigate to FX Selection Navigate to Mixer View

Reference Guide
13
Reference Guide
Mixer View continued...
The thin illuminated strip surrounding the main
fader meter also helps indicate which mix type is
currently selected; the color varies and is dependent
on the selected output. This is the same indicator
that is also on display surrounding each input meter.
Also note how the selected output is displayed in nice,
big text and surrounded by a box of the same color as
the selected output.
In the images below, all we did was change the
selected output from Main to Aux 1 to Aux 2. Notice
how each channel’s input meter is surrounded by
the color of the selected output.
The Main output is used for the PA in nearly every
scenario. On the other hand, the Aux output(s) are
typically used as stage monitors for the band. How-
ever, auxes may be used for external effects devices,
headphone amplifers or a myriad of other uses instead.
Separate level controls for separate functions!
Main
Aux 1
Aux 2
10. GEQ Button
The GEQ button is located at the bottom of the output
strip and it allows access to the selected output (Main
or Aux) GEQ.
When tapped, all channel strips disappear and
the selected output strip – Main or Aux – remains
on the right. The rest of the screen then becomes
occupied with the GEQ settings.
Because the GEQ is part of the (output) channel
view, there is much more – text and screen shots! –
about the GEQ on page 18.
11. System View Button
The gear icon button is located in the upper-right
corner of MixerConnect and it allows access to the
System View.
When tapped, all channel strips disappear and
the selected output strip – Main or Aux – remains
on the right. The rest of the screen then becomes
occupied with the System View settings. Additionally,
the gear icon illuminates green to indicate that the
System View is open.
Simply tapping the gear icon button again returns
you back to the previous view, be it the Mixer View
or Channel View.
Stay tuned...the System View will be discussed more
on pages 19-20. But first, the Channel View!

Introduction
As mentioned earlier, the Channel View allows access
to key controls for each channel including EQ and FX
send adjustments, channel linking and compressor
level.
There are two possible channel views:
(1) The channel view for channels 1 and 2 (and 3
through 6 on the ProDX8) and the Bluetooth / Stereo
channel is displayed above and...
(2) the channel view for the FX channel is displayed
on the following page.
Notice in both views that the controls for
the currently selected channel are on the
left side and the main mix controls remain
on the right.
From here you’re able to one-touch navigate to
the Mixer View, System View, FX selection / channel,
other adjacent channels or the Graphic EQ.
12. < / >
No, this isn’t “less than divided by greater than.”
I’m pretty sure someone’s head would explode trying
to work out that math problem! Rather, these two
channel navigation buttons take you to the previous
channel [“<” button] or next channel [“>” button].
Additionally, you can switch between channels by
swiping left and right on the channel name displayed
between these two buttons.
Go ahead and switch between channels by tapping
the buttons or swiping left and right. The rest of this
Reference Guide can wait!
13. Link
Two adjoining mono input channels may be linked
together. This is ideal for stereo input sources such
as keyboards, submixer outputs, vocal processors and
more. When linked, the level control, EQ, compressor,
etc. are adjusted with a single set of controls!
Linking channels is easy. At the top of the Channel
View is an option to “Link X”. Tap it! As seen below, a
popover will ask you to confirm which channel’s settings
you prefer. Tap your channel choice...or cancel out.
The new linked channel will take on all of
the attributes [EQ settings, compressor level,
FX level, etc.] of the tapped channel button.
In other words, if you tap the Channel 1
button, the resulting stereo channel will take on all
of the settings of channel 1. However, if you tap the
Channel 2 button, the resulting stereo channel will
take on all of the settings of channel 2.

Channel View continued...
The top two screen shots below display channels 1
and 2 UNLINKED (and therefore still mono), but the
next two display the same two channels LINKED.
Notice how the channel 2 settings “disappear” and
are replaced with the settings of channel 1. Also, the
Link button illuminates green on both linked channels.
Ch 1 Linked

And as seen below, the channel faders are linked and
will grow & glow together when raised or lowered. Also
of note is the horizontal line that appears between the
linked channels’ gain reduction meters, which further
indicates just how linked they are.
From the Channel View, simply tap the “Link X”
button again to unlink channels.
3-Band Mid-Sweep EQ
MixerConnect has 3-band equalization and a low-cut
filter at carefully selected points — low shelving at
80 Hz, mid sweep peaking from 100 Hz to 8 kHz, and
high shelving at 12.5 kHz. “Shelving” means that the
circuitry boosts or cuts all frequencies past the specified
frequency. For example, dragging the low EQ slider 12
dB to the right boosts bass starting at 80 Hz and
continuing down to the lowest note you never heard and
12.5 kHz on up boosts the treble in the case of the high
EQ. “Peaking” means that certain frequencies form a
“hill” around the center frequency.
With too much EQ, you can screw things up
royally. We’ve designed a lot of boost and cut
into the equalizer circuit because we know
everyone will occasionally need that. But if
you max the EQs, you’ll likely get mix mush. Equalize
subtly and use the left sides of the EQ sliders (cut),
as well as the right (boost).
The default channel EQ setting is shown below.
EQ with boost and cut may be seen to the left.

to 12 dB boost or cut below
80 Hz. The processing is
flat (no boost or cut) at
the center position. This
frequency represents the
punch in bass drums, bass
guitar, fat synth patches,
and some really serious male singers.
A trick that we like to employ is to boost the lows
of the rhythm section of the band (e.g. kick drum
and bass guitar), then roll the low off a little on higher
frequency instruments (e.g. electric guitar and female
vocals). The rhythm section sounds huge, but the
higher timbred instruments will still cut through.
15. Low Cut
Low cut — often referred
to as a high pass filter — cuts
bass frequencies below the low
cut setting [20 Hz – 400 Hz]
at a rate of 12 dB per octave.
This ain’t no thrown-in dime-
store filter — a 12 dB per
octave curve requires an elaborate circuit.
Nothing but the best for you!
We recommend that you use low cut on every sound
source except kick drum, bass guitar, or bassy synth
patches. These aside, there isn’t much down there that
you want to hear, and filtering it out makes the low stuff
you do want much more crisp and tasty. Slide the low
cut right until you just start to hear it affect the signal.
This leaves only what you want to hear while removing
the unwanted debris. Not only that, but low cut can help
reduce the possibility of feedback in live situations.
With low cut, you can safely boost low EQ. Many
times, bass shelving EQ can really benefit voices.
Trouble is, adding low EQ also boosts the subsonic
debris: Stage rumble, mic handling clunks, wind noise
and breath pops. Low cut removes all that debris so you
can boost the low EQ without blowing your subwoofers.

16. Mid and Mid Freq EQ
Short for “midrange,” the mid slider sets the amount
of boost or cut, up to 12 dB, and is effectively bypassed
at the center. The mid-freq slider sets the center
frequency, sweepable from 100 Hz to 8 kHz.
Most of the root and lower harmonics that define a
sound are located in the 100 Hz – 8 kHz frequency
range, and you can create drastic changes with these
two sliders. Many FOH engineers use mid EQ to cut
midrange frequencies, not boost them. One popular
trick is to set the mid fully up, then set the frequency
slider until you find a point where it sounds just ter-
rible, then back the mid down into the cut range,
causing those terrible frequencies to disappear. Sounds
silly, but it works. Sometimes.
Unlike the other EQ sliders, the mid-freq EQ
slider will not illuminate blue. This is because
there is no boost or cut. Rather, it simply sets
the center frequency of the mid EQ.
17. High EQ
This slider gives you
up to 12 dB boost or cut at
12.5 kHz, and it is also flat
at center. Turn it up to add
sizzle to cymbals, and an
overall sense of transpar-
ency, or edge to keyboards,
vocals, guitar and bacon
frying. Turn it down a little
to reduce sibilance, or to hide hiss.

18. Compressor
The quick explanation of a compressor is: if
it’s too hot, turn it down, otherwise leave it alone.
A compressor is used to reduce or limit transient
peaks in a signal. As the input level to the compressor
increases, the output level increases linearly.
Dynamic range is the difference in level between the
quietest and loudest parts of a song and a compressor
“squeezes” this dynamic range, resulting in an overall
steadier, more constant volume level for the signal.
When the incoming signals exceed the threshold level
set by this slider, the signal level is automatically
compressed. It helps sources, such as vocals, “sit”
properly in the mix. More importantly, it adds an
overall “punch” to the incoming signal.
The compression ratio varies according
to where the slider sits and may be adjusted
from off (no compression, slider far left) to max
(full compression, slider far right). As with the
other features of MixerConnect, experiment with
the compressor level until you find the “sweet spot”.
The parameters of this compressor are specially
chosen to give you the best overall performance.
There is no compressor on the Bluetooth /
Stereo channel.
19. FX Send
The FX send slider controls the level being sent
to the effect from the currently selected channel.
In other words, drag the FX send slider right on
the channels you want to have effects.
For example, you might want reverb on the vocal
channel, but none on the other channels. Here you
would simply drag the FX send slider right on the
vocal channel until you like what you hear and drag
this slider to the far left on the other channels.
Tapping the FX button [Delay or Reverb] takes
you directly to the the FX channel where FX selection
occurs. More information to the right, #20 FX.
If the FX send slider is up, but no FX are
present, be sure to check that the FX return
fader is also up and applicable mute buttons
are off.

20. FX
We just looked at and dissected the channels 1 and 2
(and 3 through 6 on the ProDX8) and the Bluetooth /
Stereo input section of the Channel View, but there is
one more channel view to discuss: the FX channel view!
ProDX includes 16 “gig ready” effects, including
various reverbs, delays, choruses and combinations
of these, as well.
On the ProDX hardware control panel, there are four
preset effects to choose from, including Verb 1, Verb 2,
Delay 1, or Delay 2.
Additional effects may be selected via MixerConnect.
The app also adds control over the master FX return
level.
As seen in the screen shot below, this is where
to select an effect to add to the input channel.
The button of the currently selected effect will
illuminate green.
Only one effect may be selected at one time,
but there are separate FX send level sliders
for each channel.
The FX level of each output is set by that
output’s FX return level [see #6, page 12].
Be sure to check out a more detailed
description of each effect in Appendix C,
page 24.

21. GEQ View
Graphic EQ is a great tool for really dialing in the
response needed for a room [Main GEQ] or to squelch
feedback from monitors [Aux GEQ].
As with the channel EQ, just take it easy. Although
it may not seem cool to turn down controls, with EQ
it is often your best option. There are no prizes for who
can EQ the most (or is there?).
Simply turn down any offending frequency range,
rather than boosting the wanted range. Having many
sliders will allow you to reduce the level of some
frequency bands where feedback occurs. Or if a lot
of EQ seems necessary, then chances are that the
system can be improved by careful re-positioning
of the microphones and other equipment.
Getting to the ProDX’s GEQ is easy! First, using
the Mix Selector, tap the output that you want to dial
in the GEQ for, then tap the button located at the
bottom of the selected output strip to open it.
When tapped, all channel strips disappear and
the selected output strip – Main or Aux – remains
on the right. The rest of the screen then becomes
occupied with the GEQ settings.
Navigate to GEQ Navigate to Mixer /
Channel View
As seen below, there are seven graphic EQ sliders.
Moving a slider vertically changes that frequency’s gain
by up to ±12 dB. Drag these sliders up or down until the
desired sound has been achieved. Tapping a band’s
graphic EQ slider twice will zero it.

System View
Introduction
As mentioned earlier, the System View allows access
to the Memory screen, the Phones level and the About
view.
Here the selected input channel disappears,
but the output strip and its corresponding
controls remain.
There are multiple system menu buttons from
which to choose from. As seen below, the button
of the currently selected menu will be backlit black
along the top of the view.
With a simple, single tap of the Tools – gear icon –
button you’re able to one-touch navigate back to the
previous view, be it the Mixer View or Channel View
[horizontal sliders displayed] or GEQ [vertical sliders
displayed].
22. Memory
When the memory tab is selected, settings for ProDX
may be saved to memory and recalled at a later time.
What’s more, each setting may be custom-named! No
more having to reset levels, EQ and FX upon every
power-up or trying to remember what “Preset #2” is.
Hint: it’s not “Karaoke”; that’s Preset #3...of course!
There are three user presets and a fourth to recall
the factory default settings. Left to right are the save
button, preset number, recall button and preset name:
Save Button – Tap this button to save the current
settings to the corresponding preset.
Be careful when saving presets, as the new
settings will replace the currently saved
settings.
Preset Number – While the preset name is user-
editable (see above-right), the preset number will
remain as-is, in order.
Recall Button – Tap this button to recall the
settings of the selected preset.
Preset Name – Tap in the name box to bring up the
blinking cursor and keyboard. Simply type in the name
you want for that preset followed by a carriage return.
If the name is too long to fit, it will display the
first 15 (or so) characters followed by an ellipses...
[Actual length varies by ±3 characters depending on
device used].
Factory Default Recall Button — Tap this button
to return all settings – faders, mutes, FX, etc. – to their
original factory settings. It is a convenient way to start
with a fresh slate, essentially “zeroing out” the mixer.
This is not the same as the “Vulcan Mind
Meld” which will ERASE all settings, as well
as the memory of previously paired devices.
See ‘Factory Reset’ on the following page.

23. Phones
With headphones connected to the phones jack
and the Phones tab selected, you are able to raise
and lower the headphone level.
Here, the phones slider controls the level being
sent to the headphones. Simply drag the Phones
Gain slider right to raise the level on the headphones
and left to lower it. The “Phones Gain” label will
display the phones value as the phones level is
adjusted. The phones level ranges from –∞to +12 dB.
The phones jack is post-everything, so the signal that
is sent to the phones output is the same signal that’s
sent to the main outputs. But with separate master
level controls you’re able to cue intermission music
via phones before sending the signal to the main PA.
WARNING: The headphone amp is loud
and can cause permanent hearing damage.
Even intermediate levels may be painfully
loud with some headphones. BE CAREFUL! Always
turn the phones slider control all the way left before
connecting headphones or doing anything new that
may affect the headphone volume. Then turn it up
slowly as you listen carefully.
24. About
Once tapped, the About tab displays information
about the MixerConnect app version that is currently
installed on the device.

Factory Reset — Since settings may be changed via
MixerConnect, it may be necessary to reset the ProDX
to its factory settings. This process is known around the
office as the “Vulcan Mind Meld”.
Please keep in mind that this erases all settings,
including any levels, EQs, etc. that may have been
set. Be sure to power down any amps and/or powered
speakers before resetting ProDX.
Simply tap the ‘Factory Reset’ button or press and
hold the following buttons simultaneously for a few
seconds to reset the ProDX to its factory settings:
• Channel 1, Channel 2 and MAIN buttons.
You are also wiping the ProDX’s memory
of previously paired devices. To remedy this,
on your smartphone, tablet or other Bluetooth
device, you will need to ‘forget device’ in the Bluetooth
settings, then re-pair in order to regain communication
and functionality.
