INSTALLATION INSTRUCTIONS
Mechanical Installation
UXA Series Owners Manual
The UXA Series Amplier must only be operated when mounted in a standard 19”rack enclosure.
Where the amplier is used in a xed installation, as long as the bottom unit is supported and there are no gaps
between units, it is acceptable to use only the front panel 19”rack mounting points when tting it in a standard
rack enclosure. If the amplier is mounted in a mobile rack it is important that the rear is supported with a rear
482

UXA Series Owners Manual
rack mounting kit part number 2050314, included with every amplier. Damage caused by insucient support is
not covered by the manufacturer’s warranty.
To prevent damage to the front panel it is recommended that plastic cups or washers are tted underneath the
rack mounting bolt heads.
It is possible to mount multiple UXA Series ampliers without ventilation gaps between them but it is essential
that an unobstructed ow of clean air is available from the front of the unit to the rear.
IMPORTANT
General
The amplier should never be exposed to rain or moisture during operation or storage. If the unit does come into
contact with moisture, remove the AC power cord immediately and leave it in a dry and warm location.
Note that when any equipment is taken from a cold location into a warm humid one, condensation may occur
inside the device. Always allow time for the equipment to attain the same temperature as its surrounding
environment before connecting the AC power cord.
It is the responsibility of the user to ensure that dirt, liquids and vapour from theatrical smoke and fog machines
is not ingested by the amplier. Damage so caused is not covered by the manufacturer’s warranty.
Cooling
It is important that neither the air intakes on the front of the unit or the exhaust vents at the rear are obstructed.
Steps must also be taken to ensure that hot air does not continually circulate through the ampliers from the
back of the rack to the front.
The air intake lter must be cleaned regularly with warm water and a little detergent to ensure unrestricted
airow. The lter can be removed without the use of tools by gently pulling it out of its aperture. When retting
ensure that it is thoroughly dry and that there are no areas of the grille not covered by the lter element.
Operating the amplier without the air intake lter will invalidate the manufacturer’s warranty.
AC Power Connection
The amplier utilizes a 32A Neutrik PowerConTM type locking AC power connector. Use only an AC power cord
correctly terminated with a genuine NeutrikTM PowerConTM. It is the responsibility of the user to ensure that all
wiring is performed by a qualied person in accordance with all local regulations.
The ampliers are designed to operate on 115V 60Hz or 230V 50 Hz nominal AC power, automatically conguring
themselves at switch on. Note that although the ampliers will operate when the mains supply is within the
range specied in this document, various specications will only be met when the unit is operated at the stated
nominal voltages.

Greyboxes include:
EAW Focusing
By deploying advanced signal processing EAW Focusing corrects for mechanically
induced anomalies in the loudspeakers acoustic system and provides a pure
impulse response. This means the sound you hear is true to the original version free
from time smear created by intra-cabinet reections.
Crossover Settings
What is a Greybox?
A Greybox is a le that includes everything you need to get optimal performance from an EAW loudspeaker.
‘White’component that is user accessible.‘Black’component that is EAW-provided and locked down.
Mix together = Grey.

Audio Connections
Input Connections
For each input channel there is a female XLR connector for analog inputs. There is also one female XLR for one
stream (two channels) of AES3 digital audio. Note that only two channels of AES3 digital audio are available. The
Dante permits more channels of Digital Audio inputs.
The HOT, or + connection should be made to pin 2 of the XLR connector.
The COLD, or - connection should be made to pin 3 of the XLR connector.
Pin 1 of the XLR connectors is internally connected to the chassis. The shield of the input cable should always be
connected Pin 1 of the XLR to ensure that EMC performance and regulations are met.
DynO (where applicable) & limiters
Dynamic Optimization, which maximizes the output of every passband. This tangibly
increases output over what would otherwise be possible.
Air Loss Pre-emphasis Filter
A distance, temperature and humidity-dependent air loss pre-emphasis lter
improves high frequency projection by correcting for expected air losses
for longer distances.
Easy Conguration
Just enter the loudspeaker model and amplier you are using in the Greybox setup
window. Resolution automatically applies the Greybox settings and optimizes the
entire system in seconds.

UXA Series Owners Manual
Amplier Output Connections
Note : The UXA4406, UXA4410 and UXA4810 series ampliers can produce high voltages at their outputs.
Always use genuine Neutrik NL4 connectors. Un-bridged outputs must use Class 2 or class 3 wiring. Bridged
channel pairs must use Class 3 wiring. Custom wiring must only be performed by qualied personnel.
The UXA4406 and UXA4410 amplier is tted with one NL4 connector per amplier channel.. The appropriate
conductor terminations are shown below and on the rear panel of the unit.
14
Using unbalanced connections
Please note that the use of unbalanced connections is not recommended, however when connecting the
amplier to an unbalanced audio source, the signal conductor should be connected to XLR pin2. The ‘Cold’
conductor or cable screen should be connected to XLR pin 1 with a short connection made between pin 1
and pin 3.

UXA Series Owners Manual
More than one speaker can be connected to each channel provided the total impedance per channel is not less
than 2 ohms. In bridged mode the minimum total impedance should not be less than 4 ohms.
Load Matching
Each output of the device can be optimised to drive either a low impedance load (e.g. 2, 4 or 8 Ohms), or a
Constant Voltage (C.V.) using the Load parameter in the Output menu. There are several C.V. settings (25V, 70V
and 100V Line) which determine the maximum RMS voltage that the amplier will produce. Select the one
which is appropriate for the installation. A number of low impedance settings (depending on the model) are
also available. Although it is not critical that this setting matches the impedance of the connected load, this will
maximise the power that is available for the load.
15
Additionally, the channel 2 output is duplicated on the NL4 connector for amplier channel 1 for Bi-Amp wiring.
Similarly, the channel 4 output is duplicated on the NL4 connector for amplier channel 3. This can be useful for
making a connection to two loudspeakers with one 4-core cable (i.e. Bi-Amp).
On the UXA4810 model, all outputs are Bi-Amp; each NL4 connector carries two amplier outputs – Channels
1&2, Channels 3&4, Channels 5&6 and Channels 7&8.
In addition, the channel 1 or channel 3 connector (all the NL4 connectors on the UXA4810 model) can also be
used if the pair of amplier channels is being operated in bridged mode.

UXA Series Owners Manual
Panel Layouts
16
(The UXA4406 or UXA4410 is illustrated. The UXA4810 is similar, but with more output indicators and mute buttons)
1. Input Signal Indicators– A set of ve indicators show “Sig”,“-12”,“0dBu”,“+6” and“+12” and “Clip (mute)” for each of the
DSP inputs “A”“B” “C”“D”. The signal present Indicators operate at approximately –40 dBu. The Clip/mute Indicators warn the user
of input overload and operate at 1dB before clip. This indicator also shows a muted input.
2. Power Switch– Applies mains power to the device. If the device has entered Sleep mode, it may be woken up again either from
the EAW Resolution software application, or by switching this switch o, then on again.
3. Menu Buttons– There are three buttons to determine which section of the device to view or edit. The <OUTPUT> button
displays pages of parameters associated with a particular output channel. The <INPUT> button displays pages of parameters
associated with a particular input socket or input DSP channel. Pressing <INPUT> or <OUTPUT> buttons repeatedly will scroll
through the inputs/outputs of the device. After the last channel, navigation returns to the Home screen. The <UTILITY> button
displays pages of miscellaneous parameters not associated with any particular channel. Whilst in Edit mode, one of these three
buttons will be illuminated. They are mutually exclusive – pressing one of the buttons will deselect any others that are active.
Pressing Utils will escape back to the Home screen.
4. Page Selection Buttons– When one of the buttons <INPUT>, <OUTPUT> or <UTILITY> is illuminated, the up <P> and down
<Q> arrows will also illuminate, informing the user that these buttons may be used to scroll through the various pages of
parameters that may be viewed and edited. The <ENTER> button is used to conrm an operation. It will illuminate when the user
is being invited to press it. It will ash when warning the user that pressing this button will activate an important function.
5. Graphical Display– This will show the Home screen; a useful overview of channel allocation. On most pages the currently
selected channel and parameter information is displayed on the upper part of the screen and the parameter value on the lower
part of the screen; this can also optimise the viewing angle.
6. Status Indicators– The “OVERLAY” indicator indicator is not currently used. The <DANTE AUDIO> indicator illuminates when
one or more of the inputs is using a dante source. The “ONLINE” indicator has three states: O– the unit is oine and not
connected to a computer or network. Flashing– the unit is searching for an IP address; if the unit does not nd an IP address the
unit will assign itself an IP address automatically and the indicator will stop ashing. On– the unit is online and connected with
software. IP settings can be viewed or changed within the <UTILITY> pages. The“AES3 IN” indicator illuminates when one or
more of the inputs is using an AES3 source.
7. Parameter Encoders– Two velocity sensitive parameter encoders are used to adjust parameters shown on the display. Up to three
parameters at a time are displayed on the screen. The parameter name is shown above the parameter value in each of the three
screen sections. Use SELECT to highlight the parameter, then ADJUST to change it.
8. Bridge Indicator– This will illuminate when the channel pair is in Bridge mode. The controls for the left channel of the pair will
determine the settings. See Bridge Mode
9. Mute Buttons– DSP output mute status is indicated and controlled by an illuminated button for each channel. These ash
when the entire unit is muted from the AUXA port or from EAW Resolution software Mute-All, or if this channel has been muted by
the protection systems.
10. Amplier Indicator– This indicates when the amplier protection systems are reducing the gain to keep the parameters of the
amplier within specication, or when that the channel is clipping.
11. Driver Indicator– This indicates the output limiter is engaged.
12. Limiter Indicators– The output indicators shows the status of the limiter and output level. The level indicated is that before the
limiter, referenced to the limiter threshold. The <SIG> indicator shows when a signal is present on the output. The second indicator
<-6dB> shows that the signal has reached 6dB below the limiter threshold. The third <LIMIT> indicator indicates that the
threshold of that output channel has been reached.

17. Analog Audio Input Connectors– All audio connections are fully balanced and wired: pin-1 to chassis (as required by the AES48
standard), pin-2 hot & pin-3 cold.
18. AES3 Audio Link Connector– The Link connector carries a buered version of the signal on the AES3 input connector. In the
event that an amplier is not powered, AES3 input and Link are directly connected. Do not‘daisy-chain’ more than 8 ampliers from
a single AES3 source.
19. AES3 Digital Audio Input Connector– The Input is fully balanced, transformer isolated and terminated. It is wired: pin-1 to
ground, pin-2 data+ & pin-3 data.
20. Dante Audio Ports– Used to connect to Dante network. Can be congured for switched or reduntant operation.
21. Ethernet Communications Port– Used for remote control and monitoring via Resolution Software.
22. AUXAiliary Port– The aUXAiliary port may be congured for a variety of purposes. See the AUXA Port section.
23. Mains Power Inlet– Connection to the mains supply must only be made with a genuine NeutrikTM PowerconTM 32A connector.
The amplier is designed to operate from a nominal mains voltage between 100V and 230V, 50/60Hz without re-conguration.
NOTE: The amplier must be connected to a suitable mains earth; failure to do so will aect safety, performance and will invalidate
the manufacturer’s warranty.
24. Relay Output– This isolated relay output may be used to indicate abnormal conditions to external monitoring apparatus.
See the Fault Relay section.

Operation
Starting up the unit
When power switch is switched on the unit will go through its start-up cycle, checking all the sub-systems as
it does so. Along the way, the screen will inform you of its progress. Once this is complete the display will then
show the Home screen indicating input/output congurations.

Navigation
Parameter navigation and adjustment on the UXA Series is very straightforward. There is no concept of drilling
down deeper into hidden menus; every parameter is accessible by simply scrolling across a‘map’of parameter
pages which can be thought of as placed on a 2-dimensional grid. Horizontally across the width of the grid are
the various channels, and vertically up and down the grid are the parameter pages for each section
of processing.
To view a parameter, repeatedly press the desired <INPUT> or <OUTPUT> channel button until the desired
channel is reached. Then repeatedly press the up <> and down <> buttons to scroll through the processing
parameters for the selected input/output.
Two encoders allow you to select and adjust a parameter. Often, several parameters will be shown in various
zones on the display. To select a parameter for adjustment, turn the right-most encoder such that the parameter
you wish to adjust is highlighted. Then turn the leftmost encoder to adjust the value of that parameter. Turning
this encoder clockwise will increase the value of a parameter, or anticlockwise will decrease it. The encoders
are velocity-sensitive so turning an encoder rapidly will cause the action to‘accelerate’, so the value changes
more rapidly.
Turn the SELECT encoder
to highlight the zone you
wish to adjust.
Turn the ADJUST
encoder to change
its value.

The Home Page
The Home Page presents an overview of the conguration of the device. It indicates the user-dene Device
Name at the top, and shows the four Input Channels. The top line shows the Input DSP channel (‘A’, ‘B’etc), and
the name the user has given to this channel. The bottom line shows the physical input number, and a list of the
outputs which are routed from the input channel.
AES3 Inputs
In addition to the usual analog inputs, the Device can also accept AES3 digital inputs. When a DSP input channel
is assigned to an AES3 channel, the“AES3”indicator will illuminate.
There is no‘standard’for the relative gains between Analog and AES3 so depending on the levels delivered by
the audio source, it may be necessary to adjust the digital input gain trims to normalise them. It is possible to
adjust the gain of the AES3 input using the Input Trim AES3 Gain parameter. For example, to achieve 0dBFS =
+18dBu, set the AES3 trim to -2dB. To achieve 0dBFS = +24dBu, set the trim to +4dB.
This device will automatically lock onto any sample rate within the range 28kHz and 108kHz.
