Using the Loudspeaker
Users will need to perform the following
general tasks to properly put an EAW line
source product into use. This manual includes
details for each task.
1. Design the system using the Resolution™ 2
Design & Control Software (see the program
Help File for further information about using
Resolution).
2. Design and install suspension points to
support the array(s)/rigging in intended
locations and aimed in the desired directions.
If ground-stacked, provide a level surface
capable of supporting the total weight of the
array(s).
3. Connect the loudspeakers to a supported
EAW Processor and/or power amp.
4. Set-up and adjust overall system gain and
signal processing, as needed to maximize the
array's performance for the application.
5. Provide training to operate the
loudspeakers within their limits.
6. Provide regular inspection and
maintenance to maintain the integrity of
the installation and the performance of the
loudspeakers.
Array Design
See Resolution Help File for assistance in
properly designing line array systems.
Software
EAW Resolution 2 software is designed to
assist in SPL predictions, determine splay
angles, and calculate rigging limits for all line
array items.
Always ensure that your EAW Resolution
software is up-to-date.
For a complete list of recommended system
requirements, please refer to the Resolution
2 help le.
Using EAW Resolution™
EAW Resolution is the key to determining
the optimal array conguration for any
application. Rooted in EAW’s proprietary
FChart modeling and calculation engine,
Resolution allows users to easily model any
venue and visualize a wide variety of array
designs to determine what particular array
conguration is best suited to the venue.
Users simply need to dene the array position,
allowable trim, minimum clearance, and
quantity of modules available and use the
Array Assistant to determine the optimal
array conguration for a given venue. In
many situations no further prediction work
will be necessary for optimal results. Users
can also adjust the results after running the
Array Assistant by manually adding/removing
modules or adjusting coverage and observing
changes in predicted results. In this way
Adaptive arrays can be optimized for any
application.
Additionally, Resolution interfaces directly
with Adaptive Systems via the Dante
protocol, allowing users to easily upload
the processing parameters for their system
directly from their model to the physical
array, adjust equalization and coverage, and
monitor all Adaptive components in real time.
No additional software is necessary to use
Adaptive systems.
No additional software is necessary to use
Adaptive systems.

How Array Length Aects Directivity
It would be beyond the scope of this guide to
go into the physics of how line arrays behave.
The key to directivity is array length. This
should not be confused with the number of
drivers. A properly designed line array system
will exhibit the same directivity from the
same physical length regardless of whether
this length is made up of 8”, 10”, 12” or 15”
components.
The determining factor is the length of the
array itself and how that length aects the
wavelength being produced.
The samples below show three array types
in the same venue. The rst array is very
short with only 4x KF810P-80 modules
being deployed. The contour line feature in
Resolution has been used to clearly show the
denition of the vertical contour at 125Hz. It
is clear that with this array length, the 125Hz
frequency is seeing only slight directivity
control.
The second image demonstrates what would happen with the same frequency in the same
venue but with 8x KF810P-80 line items. It is quite clear how much more directive the vertical has
become in this image and if we continue to add modules to the array, the eect will become more
pronounced.

Line Array Application Guide
Finally, we see the result when 12x KF810P-80 is deployed. This array produces an extremely tight
vertical pattern at 125Hz across this listening area. If directivity at lower frequencies is required for
the application, array length must be considered.

KF810P Input Connection
KF810P is a 3-way line array product, utlizing a passive crossover between the MF/HF. When
wiring to UXA4410, utilize NL4 in outputs 1 & 3. Connect 2 pins +/- to LF, then the other 2 pins
+/- to MF/HF into a Phoenix connector (which can then plug into the KF810P input). It's possible
to loop 2 more cabinets in the same manner using Loop Thru.

SB818P|F utilizes a 2 pin +/- Phoenix connector. Using UXA4410, use NL4 with pins 1 +/- wired,
then connect the bare wire pins 1 +/- to the connector (which can then plug into the sub). If
multiple subs are being used, use the same NL4 connector and wire the pins 2 +/- and connect
pins 2 +/- to another Phoenix connector to then plug into additional subs. When using this type
of conguration, plug NL4 connectors into outputs 1 & 3 of UXA4410. It's possible to loop 1x

KF210 Input Connection
KF210 utilizes an NL4 connection with a switch for single or bi amped operation. When the
switch is in single amped mode, pin 1 only is utilzed. When in bi amped mode, pin 1 +/- is LF,
and pin 2 +/- is HF. When wiring to use with UXA4410 in single amp mode, plug NL4 into any
output on the amp, then directly into the cabinet (NOTE: Pin 2 +/- will be unused). When using
bi amp, plug into UXA4410 outputs 1 & 3, then directly into the cabinet. It's possible to loop 3x
more cabinets in either mode.

Using UXA4410 Power Amplier
It is required to use an EAW amplifer with any EAW line array products. Important processing
such as limiting, FIR lters, and DYNO (Dynamic EQ) is prudent to the loudspeakers
performance.

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
Panel Layout

Tel [phone] | www.eaw.com 16
Line Array Application Guide
<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.
Amplier Output Connections
Note : The UXA4410 amplier 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 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.

Tel [phone] | www.eaw.com 17
Line Array Application Guide
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.

Line Array Application Guide
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.
Going Online with UXA4410
Before going online, assure the computer being used is connected to the same Ethernet
network as the UX/UXA units. Two network cables will need to be connected to the processors/
ampliers for Control and DSP (one to the ETHNET port, the other to one of the DANTE ports).
NOTE: If processors/ampliers are on a DANTE Network consisting of more than 2 multicast
ows, communication issues may occur. As such, the UX/UXA products are only supported
on DANTE networks with 2 or less multicast ows. Also important, is though these products
may receive DANTE input signal, they do not support DANTE output (i.e. cannot be used as an
onramp).
When rst opening Resolution, start by switching to Network Conguration View.
