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.

HOW TO USE THE FLYING FRAME SV-CXA
• The ying system SV-CXA is constructed with steel. The ying frame is composed of an upper support
with a xed transversal front piece and an adjustable transversal rear piece. All the cabinets are hung from
this ying frame, one beneath the other correspondingly.
When using the ying frame with the CXA-12 enclosures (Figure 1) they are supported via 2 points with 1
lateral plate incorporated in each cabinet and a special steel pin per side.
• When using the SV-CXA with the sub units (Figure 2) they are supported via 4 points with 2 lateral plates
incorporated in each cabinet locked with two special steel pins per side.
The support of the cabinets to the ying system is carried out with special 6mm steel pins. To extract or x
the steel pins it is necessary to press the central button of the pin.
