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

10

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

TM

correctly terminated with a genuine Neutrik

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.

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.

Greyboxes include:

Crossover Settings

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.

12

UXA Series Owners Manual

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.

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.

13

UXA Series Owners Manual

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.

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

UXA Series Owners Manual

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.

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.

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.

(The UXA4406 or UXA4410 is illustrated. The UXA4810 is similar, but with more output indicators and mute buttons)

13. Loudspeaker Connectors (UXA4810)– Odd channel numbers are connected to the 1+ and 1- terminals, even channel
numbers are connected to the 2+ and 2- terminals. For Bridged mode, use terminals 1+ and 2+. Only use genuine NeutrikTM
SpeakonTM connectors.

14. Loudspeaker Connectors (UXA4406 and UXA4410)– The numbered connectors carry their corresponding channels on the
1+ and 1- terminals. Connector 1 also carries the output for channel 2 on terminals 2+ and 2-. Similarly, connector 3 also carries
the output for channel 4 on terminals 2+ and 2-. For Bridged mode, use terminals 1+ and 2+ of either CH1 or CH3. Only use
genuine NeutrikTM SpeakonTM connectors.

15. Air Exhaust Vents– These must not be obstructed and there must be a clear path for hot air to exit any rack system.
corresponding analog input connectors.

16. Analog Audio Link Connectors– These are directly connected to their corresponding analog input connectors.

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.

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.

Device Name DSP Input

Outputs AssignedPhysical Input

Input Name

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.

20

UXA Series Owners Manual

Dante Inputs

It is possible to select any channel(s) as being sourced from the Dante network. To do this, connect the Dante
network connection to the connection on the rear of the Device, and set the relevant Input Type menu Type
parameter to “Dante”.

When a Dante channel is routed to an input, the “Dante Audio” indicator above the encoders will illuminate. This
indicator will come on even if there are no cables plugged into the networked audio port on the Device.

As for the AES3 inputs, it is possible to set the relative gain between an Analog input and the signals sourced
from the Digital Audio Network using the Input Trim Dante gain parameter.

The amplier will automatically select the correct sample rate from the incoming stream.

For other details on the operation of the Digital Audio Network, please refer to the relevant
manufacturer’s documentation.

Automatic Input Selection (Fallover)

It is possible to congure the input selection to be automated. The Input TYPE screen has a Fallover parameter,
which defaults to Manual, allowing you to select what Type of input you wish to use. When Fallover AES3>Analog
is selected (on an input channel which supports AES3), then the AES3 source will be automatically selected if it
has a valid audio stream on it. If the AES3 stream should fail, then Analog is automatically selected instead.

When Fallover Dante>Analog is selected, then the Dante source will be automatically selected if it has a valid
audio stream on it. If the Dante stream should fail, then Analog is automatically selected instead.

Similarly, it is possible to select Fallover Dante>AES3 on a channel that supports AES3.

The ‘Auto’ setting allows the highest priority input source that is active to be automatically selected, so the user
could just plug a source into any input and it will be automatically selected. The priorities are: Dante rst, AES3
second, Analog third.

Note that any automatic selection will take precedence over manual selection, so if you try to manually select
Dante when there is no valid Dante stream, then it will revert to the fallover input source.

Gain and Polarity

The gain page of the input channel selected allows users to increase or decrease the amount of signal going into
the selected input. Using the “SELECT” encoder to highlight the Gain value allows the value to be changed by the
“ADJUST encoder in 0.2dB steps from -40dB to +20dB. This page will also allow users to change the polarity of the
selected input from normal to reverse. And to mute the selected channel.

Delay

The delay page which controls the amount of delay associated with the input channel selected and is adjustable
from 0 to 998ms. The delay parameter is adjustable in ne steps at low values; the adjustment becomes
progressively coarser as the value increases.

21

UXA Series Owners Manual

UXA Series Owners Manual

High Pass Filter

System high pass ltering is provided for the input signal. Filter type is selectable from 1st order, Butterworth,
Bessel, Linkwitz-Riley and Hardman. Filter slopes of up to 4th order or 24dB / octave are provided. Not all lter
types are available in all slopes. For example 18dB / octave Linkwitz-Riley lters do not exist.

The Hardman type lter is always described by its order as the lter becomes progressively steeper rather than
following a linear slope so a dB/octave description is not accurate.

Parametric Equalization

There are nine stages of equalization available for each input channel, three shelving lters and six
parametric lters.

FIR Linear Phase Equalization

The Input High-Shelf Equalizers use Finite Impulse Response (FIR) ltering to produce Linear Phase equalization;
that is all frequencies are delayed by the same amount, perfectly preserving the transient response. This can also
be important in applications where dierent amounts of EQ are applied to dierent parts of a speaker cluster,
such as to add ‘Throw’ EQ boost so that parts of cluster which are throwing further can have HF absorption
correction added. If this EQ is not linear phase, then the zones where the speakers combine may suer frequency
response anomalies.

Being a linear phase FIR equalizer, this necessarily introduces some latency delay, which is constant regardless of
the settings. However, when the ‘Enable’ parameter is set to “O”, it is removed from the signal path entirely, so
it does not add any latency. In this page you can change the frequency parameter from 2kHz to 20kHz, enable/
disable the lter, and change the cut or boost in 0.2dB increments. The lter (and its associated latency) can be
completely removed by setting the enable parameter to the “O” position.

Also see Bandwidth Units in Utilities.

Parametric Filters

Parametric lters are dened by frequency, bandwidth and gain. The frequency is adjustable over the range
from 10Hz to 25.6kHz. The bandwidth shown as Width on the screen, ranges from 0.10 octaves to 5.2 octaves.
Bandwidth can be shown and adjusted as Q or Octaves (Oct). Gain is adjusted in 0.2dB increments.

Also see Bandwidth Units in Utilities.

Routing

Routing allows users to route any physical analog or digital signal channel to any DSP input. This is eectively a
matrix mixing system where all DSPs can be driven from any one input, or from combinations of inputs “1+2”,
“3+4”, “1+3”, “1+4”, “2+3”, “2+4”, “1+2+3” or “1+2+3+4”. Summed inputs each have appropriate attenuation
so that a sum of largely similar programme material remains at the correct calibrated level.

Output

Gain and Polarity

The gain page of the output channel allows users to increase or decrease the relative signal gain for the selected
output. The Gain value may be adjusted in 0.2dB steps from -40dB to +20dB. This page will also allow users to
change the polarity of the selected output from normal to reverse.

Delay

The delay page controls the amount of delay associated with the output channel selected and is adjustable from
0 to 998ms. The delay parameter is adjustable in ne steps at low values; the adjustment becomes progressively
coarser as the value increases.

High and Low pass Filters

High pass and low pass crossover ltering is provided for the output signal. Filter type is selectable from 1st
order, Butterworth, Bessel, Linkwitz-Riley, Hardman and LIR Linear Phase. Filter slopes of up to 8th order or 48dB /
octave are provided. Not all lter types are available in all slopes. For example 18dB / octave Linkwitz-Riley lters
cannot be selected because they do not exist.

The Hardman type lter is always described by its order as the lter becomes progressively steeper rather than
following a linear slope so a dB/octave description is not accurate.

Parametric Equalization

There are ten dierent EQ lters; two shelving lters and eight parametric lters. Parametric lters are dened
by frequency, bandwidth and gain. The frequency is controlled over the range from 10Hz to 25.6kHz. The
bandwidth, shown as Width on the screen, ranges from 0.10 octaves to 5.2 octaves. Bandwidth can be shown
and adjusted as Q or Octaves (Oct). Gain is adjustable in 0.2dB increments.

Limiter

Three parameters are available for adjustment:
Threshold – the continuous RMS voltage which the driver should be able to withstand. This is calibrated at
the output of the amplier. The Limiter can be defeated by setting the Threshold to the maximum
“O” value.
Attack – The time-constant of the speed at which the driver heats up (in seconds).
Release – The time-constant of the speed at which the driver cools down expressed as a multiple
of the Attack time.

Please note that whilst the limiters in this product oer protection for amplier and drivers, they can never
protect from all possible scenarios, therefore, EAW is not responsible for any damage which might occur.

Bridge

When an amplier pair is set to Bridge Mode, it uses two amplier channels to drive one loudspeaker with
greater power. In this mode, only one set of Output controls is active per pair of amplier channels since both
of the ampliers in the pair are driven with the same signals, as determined by the left-hand (lower numbered)
channel of the pair controls.

23

23

UXA Series Owners Manual

Bridge Mode is enabled or disabled in the AMP page for a given odd numbered Output. When enabled, the
Bridge indicator will be illuminated between the bridged channels.

When Bridged, the partner (even numbered) channel will not show any signal on the limiter meter, and the
Mute button will not operate, neither will you be able access any of its parameters for adjustment. The Amplier
protection indicator however will still operate.

Routing

Outputs can be driven from any DSP input.

Driver

The optimal drive level may be adjusted for a given driver impedance using the Load parameter.
See Load Matching.

The live measured impedance value is also shown on the Driver page. Since the device can only measure
this when there is a signal, the impedance is indicated as “?” when there is insucient signal level to perform
a measurement.

Utility Pages

Screen Contrast

The Screen page in the “UTILITY” section adjusts the contrast (and optimal viewing angle) of the screen from
0-100% in 1% increments.

Current Ethernet IP Address

This may be viewed in the “IP Curr” page of the “UTILITY” menu. This value cannot be edited.

IP Mode

The Ethernet IP address may be automatic “Auto” or may be a xed static value “Static” as determined by the
“IP Mode” page of the “UTILITY” menu.

WARNING – Do NOT use Static mode unless your IT system specically requires it. Auto mode should

always be used where possible since in this mode, the Device can always be ‘discovered’ by EAW
Resolution software application. When in Static mode, the IP Address will ash on the Home screen.

Also see Ethernet Congurations.

IP Static

This allows the Static Ethernet IP address to be adjusted by the rotary encoders on the IP Static page of the

“UTILITY” menu. This page will only be visible when in Static mode.

Bandwidth Units

This page of the “UTILITY” menu allows the Bandwidth of Parametric Equalizers to be viewed and adjusted in
either Octaves or ‘Q’.

24

UXA Series Owners Manual

ECO

This page of the “UTILITY” menu allows the device to save power by going into a low power mode when
it is not being used.

Standby is a fast mode which saves some energy, but will wake-up very quickly if an audio input is detected. The
associated Standby Time parameter allows the amplier to automatically go into power-save if no audio signal
has been detected for a period of time. This function can be defeated by setting the latter control to Manual.
Linea would strongly advise leaving it set to automatic however as there is no negative consequence to doing
this since ‘wake-up’ on detecting the presence of an audio input signal is instantaneous.

The Standby Now ‘parameter’ allows the amplier to be put into standby mode manually when it is not
being used.

Sleep is a deep power save mode which saves the most energy, however it will take a small number of seconds
for the amplier to wake-up, and it may only be woken up manually (either from EAW Resolution software
application or by switching the device o then on again). The associated Sleep Time parameter allows the
amplier to automatically go into Sleep mode if no audio signal has been detected for a period of time. This
function can be defeated by setting the latter control to Manual.

External Breaker Protection (EBP)

The Power (“PWR”) utility page provides access to the External Breaker Protection (EBP) feature, which allows the
output power to be limited in order to prevent the nuisance tripping of mains circuit breakers or fuses when the
amplier needs to be operated on a mains supply with restricted capacity. Set the EBP value to that of the circuit
breaker or fuse to which the amplier is connected.

Ethernet

Ethernet congurations

IP addressing in the Device can be completely automatic; No setup is required.

DHCP

There are two primary IP address ranges – one used when there is a DHCP server, and another (‘Link Local’)
where there is no DHCP server (so the Device and the Computer will instead use ‘Auto IP’ to allocate themselves
an IP address). Both the device and the computer must be in the same IP address range. In a local network
environment such as an oce where there is a DHCP server, both the computer and the Device will be in the
DHCP IP address range, and so will connect immediately.

AUTO-IP

The device will initially search for a DHCP server when rst switched on (during which time its Online Indicator
will be ashing). As it can take up to one minute to establish that there is no DHCP server available, this is the
time it may take before Auto IP is entered.

Please be aware that it can also take some time from a computer being switched on in an isolated network
(without a DHCP server), or unplugged from a network with DHCP to time out of DHCP searching, so it will not
connect immediately to ampliers that are already using Auto IP. The time it takes before it decides to revert to

25

UXA Series Owners Manual

Auto IP depends on the operating system but it can take several minutes to acquire an Auto IP address.

Static-IP

If the device or the computer has a static IP address set, EAW Resolution software may not be able to ‘see’ the
device if it is in a dierent IP Address range (i.e. in a dierent subnet).

AUX Port

The AUX has two inputs, X & Y. These allow simple contact closure devices (relays or switches) or external logic
signals to change the state of the amplier as described below. Connecting an AUX input to ground (the earth
symbol) will trigger it; there is no requirement for an external voltage. However, the ports can also be triggered
directly by a logic signal as long as the logic ‘low’ goes below +0.5V. Do not connect systems if their logic ‘high’
voltage exceeds +24V.

The AUX port is congured with the following functionality.

• Mute+Sleep (State) – The device may be muted by grounding AUX X or placed in Sleep by
grounding AUX Y

This table shows the action taken for various AUX connection patterns in the various AUX port modes:

AUX X AUX Y

Open Open No Change

Gnd Open Mute

Open Gnd Sleep

Gnd Gnd Sleep

Mute+Sleep

(State)

Secure Mode

When activated, this will disable all the front panel controls so they cannot aect the signal path, making the unit
secure against tampering. When in secure mode, the indicators still operate normally. To activate secure mode,
press and hold the utility button for 5 seconds. To deactivate, press and hold the utility button for 5 seconds.
When in secure mode, this will be shown on the display. Note that the Ethernet communications port is still
active in secure mode.

Protection Systems

Comprehensive protection features preserve the longevity of the loudspeaker and amplier by continuously
monitoring several critical parameters, and reducing the gain, or muting the amplier either temporarily or
permanently depending on the nature and seriousness of the fault or misuse. The amplier will recover and
restart if at all possible, but may remain in shut down if a serious fault persists.

Limiters deal with routine over-driving of the amplier, making sure that the driver(s) are not pushed too hard.
The limiter indicators will warn you when the driver is being driven into limit.

Minor faults are dealt with by ‘dimming’ the amplier, reducing the level to a sucient degree and for a sucient
time that the amplier is able to recover gracefully without any user interaction. When the fault condition has
passed, the amplier will recover automatically.

26

UXA Series Owners Manual

When the protection systems are reducing the level, this is indicated by illuminating the left-hand Amplier
channel protection indicator. This will also illuminate when the output voltage is ‘clipping’.

This indicator will remain permanently illuminated if the channel has been muted by the protection systems.
The Mute button will also ash. This will usually also be indicated by a warning message on the display.

Some types of protection aect all output channels, so you may see the Amplier indicator illuminated,
and the Mute button ash, on every channel.

Summary of Protection Indication

The reasons for the protection indicators illuminating are summarised as follows:

Amplier Indicator Driver Indicator Notes

Limiter engaged

Amplier clipping

Amplier clip limiting

Amplier Current limiting

Amplier VHF limiting

PSU Current limiting Will show on all output channels

PSU Power limiting Will show on all output channels

Thermal limiting Will show on all output channels

Incident Reporting

Fault Relay

Three connections are available via the Phoenix connector for this relay. The schematic representation printed
on the rear panel shows the ‘idle’ state of the relay (when the amplier is not switched on). When the amplier is
switched on, the relay will normally energise. When a Fault incident occurs, the relay will be de-energised. This
will allow either a Fault Incident or a loss of power to be seen as a ‘Fault’.
