CONNECTORS AND CONNECTIONS
To connect the speakon follow the instructions in g. 1
Insert the male speakon in its corresponding hole and turn right until it clicks. This xes it safely and strongly
and helps stop it being pulled out by mistake. At the other end of the cable connect in the same way to the
amplier channel.
2.3 Recommendations
Always ensure cables are in good condition. Know the recommended cable length and thickness according
to the cabinet and quantity you are installing. An incorrect connection can affect the functioning of the
system or even damage it. Cable thickness will vary according to cabinet impedance, quantity and distance.
This is especially important when connecting Subwoofers.
As a guide, please see the following table which outlines the thickness depending on the power and length
of cable.
Bear in mind Ohm ratings on the ampliers used to power the cabinets. For example, 2 ohm amplier
congurations are not recommended due to the excessive power from the amp output.
Never connect more cabinets than recommended in parallel. With parallel connections, the total
impedance can be calculated by dividing the impedance of 1 cabinet by the number connected.

•Mounting advice
The KR cabinets are designed to be used in all kind of xed installations.
Cabinets must be installed and suspended by professional installers.
Never place the safety of personnel at risk. Always check the accessories, slings etc are in good condition
and the suspension point is secure and free of excess weight, vibration, etc. Be careful where the cabinets
are suspended from.
All responsibility lies with the installation company.
•Coverage change with the rotatable horn
All the KR full range cabinets enable the horn to be rotated offering further coverage options. The rotatable
horn feature enables the installer to also set the cabinet up horizontally whilst maintaining the horn features
such as horizontal and vertical coverage. This is helpful in installs with low ceilings or where esthetically the
cabinet looks better horizontally.
The following KR cabinets have rotatable horns:
KR-10 (90ºx60º)
KR-12 (90ºx60º)
To turn on the horn the user must rst remove the cabinet grill, unscrew the horn, rotate it 90º and screw it
back in. Be sure to maintain the connection and put the grill back on.

HOW TO USE ACCESSORIES FOR INSTALLATION
•UBR (U bracket):
UBR is the horizontal mounting system specially designed for Lynx Pro Audio cabinets. It is composed by
the U type support made of steel and 4 special xing screws (2 per side) in order to x the cabinet to the U
support.
Back of the cabinet Cabinet front grill
•How to use it?
Before starting with the installation please note that the UBR bracket offers three different options and you
have to select one of them before installing the support. Simply check the following drawings and select the
best option in order to achieve the coverage required.
The angles show the different variations available (from A to B) in order to x the center of the cabinet (front
grill). Please pay special attention to the optimal positioning of your cabinet.

Lynx Pro Audio S.L 12www.lynxproaudio.com
HOW TO USE ACCESSORIES FOR INSTALLATION
Once your selection is made (Position 1, 2 or 3) then you can start with the installation.
The rst thing to do is to x the UBR support in the place required (ceiling, wall, oor, etc).
Always check the suspension point is secure and free of excess
weight, vibration, etc. And be careful where the cabinets are
suspended from.
Before xing it completely please check that the position of
the bracket is correct. Remember where the front side is. If
everything iscorrectthen youcanfix theUBRsupport(without
the cabinet).
It is very important to ensure that the support is strongly xed.
Please always check it. Never place the safety of personnel at
risk.
Once the UBR support is ready then you have to prepare the cabinet. You need to make some changes in
order to hook the enclosure from the U type bracket. See below.
Please have a look at the top and bottom of your cabinet. You will nd 2 screws in the middle of the top and
another two screws in the middle of the bottom. Just remove these shorts screws. You will use these holes
to x the cabinet to the UBR support, using the longer screws provided with the support kit.
If your Lynx Pro Audio cabinet is equipped with a pole mount support then just remove 2 screws of the pole
mount support (only 2) and use these holes to x the UBR support.

HOW TO USE ACCESSORIES FOR INSTALLATION
Now that everything is clear we can start with the instalacion of the cabinet. We recommend the use of the
Position 1 or Position 2, and this is how to proceed:
If you choose Position 1 or Position 2 you will have to insert two special xing screws into the cabinet (one
per side) before installing the enclosure.
So rstly, take 2 of the xing screws provided and insert them into your cabinet. Where? Have a look. Seeing
the cabinet in horizontal position simply insert one xing screw in the UPPER HOLE of each side (left/right),
but don’t insert it completly. Just keep 5 mm out of the insert. These screws will help you to hook up the
cabinet from the UBR support in order to start with the cabinet installation.
Once the 2 screws are inserted (keeping 5 mm free) into the enclosure (one per side) then you can hook up
the cabinet (from the 5 mm free screws) into the UBR support. See the point H1 in the drawing of your choice
(Position 1 or 2). Just hook the cabinet placing the screws into the points H1 at both sides of the bracket. Do
not x them completely at the moment. You will do it when the cabinet is in the desired position.
Now you have to use the appropriate curve groove of the UBR support in order to slide the other xing screw
per side and orientate the cabinet. See the curve C2 in the drawing of your choice (Position 1 or 2). Just
insert the special screw in the appropriate curve and match the thread insert of the cabinet. You must do it
on both sides of the cabinet. Do not x them completely at the moment just keep 5 mm free so you can guide
the enclosure carefully to achieve the correct coverage.
When the cabinet is in the desired position then tighten the four screws (2 per side) and the cabinet will be
correctly installed.

HOW TO USE ACCESSORIES FOR INSTALLATION
This is how to proceed in order to install the UBR in Position 3:
First, you need to have the 4 special xing screws in your hand/pocket (none in the enclosure). Seeing the
cabinet in horizontal position you will use the UPPER HOLE of each side (left/right) to insert one special
screw per side, but you won’t insert them now.
Before inserting the screws you have to hold the cabinet into the UBR bracket and match the UBR hole (see
drawing point 1) with the thread insert of your cabinet. Once hole 1 and the thread insert match then you
can insert the special screw (one per side). Don’t x the screw now, just keep 5 mm out of the insert.
Now you have to use the appropriate curve groove of the UBR support in order to slide the other xing screw
per side and orientate the cabinet. See the curve C2 in the drawing. Just insert the special screw in this curve
and match the thread insert of the cabinet. Do it on both sides. Do not x them completely at the moment
just keep 5 mm free so you can guide the enclosure carefully to achieve the correct coverage.
When the cabinet is in the desired position then tighten the four screws (2 per side) and the cabinet will be
correctly installed.

RAINBOW 3D Acoustic Prediction Software
Lynx Pro Audio’s R&D department is working on Rainbow 3D, a new acoustic simulation software with dynamic
3D features. With a sophisticated design, Rainbow 3D stands out for its speed, being able to provide a simulation
in just a few seconds. It also provides algorithms for beam steering and optimizing the listening area.
•Designed from scratch by professionals
Rainbow 3D has been programmed from scratch by Lynx Pro Audio engineers, using new programming procedures
that achieve an effective simulation with really low calculation time.
•Multiple listening zones
The program can simulate all Lynx Pro Audio’s acoustic enclosures located in a 3D space, including the classic
side, top and front views. It can also dene multiple listening zones and allows offset positioning and symmetry.
Blueprint images, textures and PNG format pictures can be imported.
•Unlimited sound sources
Allows the acoustic simulation for an unlimited number of sound sources and audio systems. You can place as
many systems (subwoofers, line arrays, columns and individual boxes) as you desire. Also, the line arrays can be
placed in stack or own conguration.
•Beam steering
Rainbow 3D has the ability to add DSP processing to the simulation and uses algorithms to control the directivity
(beam steering) in columns, without the need to tilt them physically, being able to divide the column into several
beams that point to different zones.
•Accurate optimization thanks to FIR lters
Optimized algorithms are used in the listening area to improve the sound coverage and the frequency response.
This feature can be executed in a matter of seconds. Additionally, the export of FIR coefcients can be performed
with the optimization for later loading in the DSP via Ethernet or a USB device. In the near future direct
communication with Lynx Pro Audio and OCS will be available.
•Multiple measures and tools
Likewise, the R&D department is developing multiple measurement and analysis tools for the calculated data. For
example, the sound pressure curves (SPL) in the listening areas and the capture of virtual measurements that
show the frequency response in the points of location indicated and added. Among other tools you will nd
autosplay and a wizard to set up different subwoofer arragements.
