Electromagnetic Compatibility EMC 2014/30/UE
RoHS Directive 2011/65/UE
RAEE (WEEE) 2012/19/UE

Connectors

The KR cabinets have a connection panel at the rear of the cabinet. This consists of 2 internally bridged Neutrik
NL4-MP connectors which apply no process to the signal.
Note: If pins +-2 are not used they will still be internally bridged.
The following table indicates which pins are used for all the models, with passive and bi-amplified modes.

Cabinet| Connector| Speakon connections| per box| Impedance| Rated power| Program power
---|---|---|---|---|---|---
KR-10| NL4MP| ± 1 input / link| 2| 8 ohms| 300 W AES| 600 W
KR-12| NL4MP| ± 1 input / link| 2| 8 ohms| 500 W AES| 1000 W

To connect the speak on follow the instructions in fig. 1

Insert the male speakon in its corresponding hole and turn right until it clicks. This fixes 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 amplifier channel.

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.

Maximum recommended cable length for low impedance systems

Wire section| AWG number| Cable resistance in 100 meters| Maximum recommended length (in pieces)
2 Ω| 4 Ω| 8 Ω| 16 Ω
13.3 mm| 6| 0.25 ohm| 24| 57| 122| 253
6.63 mm| 8| 0.49 ohm| 12| 28| 61| 126
5.26 mm| 10| 0.62 ohm| 10| 23| 48| 100
3.31 mm| 12| 0.99 ohm| 6| 14| 30| 63
2.08 mm| 14| 1.57 ohm| 4| 9| 19| 40
1.31 mm| 16| 2.49 ohm| 2| 6| 12| 25
0.82 mm| 18| 3.98 ohm| 2| 4| 8| 16
0.52 mm| 20| 6.28 ohm| 1| 2| 5| 10
0.33 mm| 22| 9.89 ohm| 1| 1| 3| 6

Bear in mind Ohm ratings on the amplifiers used to power the cabinets. For example, 2 ohm amplifier configurations 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.

CABINET INSTALLATION

Mounting advice
The KR cabinets are designed to be used in all kind of fixed 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 first 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.

HARDWARE AND ACCESSORIES

The KR cabinets are designed to be used in installations and the full range cabinets come with rigging points so that they can be easily installed. To fix the cabinets to a wall or to hold them from the ceiling is very easy using some simple accessories:

AGR-8
M8 eyebolt for theKR-10and
KR-12

UBR-KR10/KR12
U bracket for the KR-10 and
KR-12 cabinets

WB-20/2
Wall bracket for the KR-10
and KR-12 cabinets

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 fixing screws (2 per side) in order to fix the cabinet to the U support.

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 fix the center of the cabinet (front grill). Please pay special attention to the optimal positioning of your cabinet.

Once your selection is made (Position 1, 2 or 3) then you can start with the installation.
The first thing to do is to fix the UBR support in the place required (ceiling, wall, floor, 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 fixing it completely please check that the position of the bracket is correct. Remember where the front side is. If everything is correct then you can fix the UBR support (without the cabinet).
It is very important to ensure that the support is strongly fixed.
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 find 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 fix 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 fix the UBR support.

Now you have 2 holes available per side (top and bottom) without removing the pole mount support. And you can use the holes available to fix the cabinet to the UBR support.
Only use the special screws provided with the support kit.

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 fixing screws into the cabinet (one per side) before installing the enclosure.
So firstly, take 2 of the fixing screws provided and insert them into your cabinet. Where? Have a look. Seeing the cabinet in horizontal position simply insert one fixing screw in the UPPER HOLE of each side (left/right), but don’t insert it completely. 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 fix 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 fixing 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 fix 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.

This is how to proceed in order to install the UBR in Position 3:

First, you need to have the 4 special fixing 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 fix 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 fixing 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 fix 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 define 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 flown configuration.

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 filters
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 coefficients 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 find autos play and a wizard to set up different subwoofer arrangements.
