RCF VSA 2050 II Digitally Steerable Column Speaker (White)The VSA 2050 II is a multi amplified vertical steerable array that represents one of the latest RCF applications in terms of digital audio technology.

The VSA 2050 II is a multi-amplified vertical steerable array that represents one of the latest RCF applications in terms of digital audio technology. Thanks to powerful DSPs it processes the audio signal sent to each speaker for controlling its vertical acoustic dispersion to address the audio signal exactly to the listening area, avoiding to send the acoustic energy to ceilings and empty floors, thus not introducing bad reflections that would affect speech intelligibility, mainly in critical environments with high reverberation time. Full RDNet compatibility.
Powerful transducers
The state-of-the-art transducers developed for the VSA II offer the highest intelligibility and wider frequency response, according to RCF philosophy. A 1,4 tesla flux density is the result of the massive neodymium magnet to achieve an incredible mid frequency dynamic range. The neodymium magnet is very lightweight and helps to compact the size of the overall system.
Advanced technology
The powerful multi-channel DSP controls each of the 20 Class-D 50 W power amplifiers, which can drive the 20 transducers with an optimal headroom. The amplification circuit includes several protections and controls to operate in safe mode. The switching-mode power supply module is connected with the DSP main board to check voltage, current and temperature status data. It operates in both 115/230 Volt AC modes and in 24 DC as a backup power source. Every model includes active protection against over-voltage and over-current. During the development of the VSA, high priority was given to critical signal paths and self-monitoring components to provide easier installation, simpler maintenance, and maximum safety and reliability. Also ideal for Voice Alarm applications.
Architectural camouflage
The unobtrusive and robust aluminum cabinet blends seamlessly in any architecturally sensitive environments. The standard colors are black RAL 9005 and white RAL 9003, and custom colors are available on request. The modular design approach offers a uniform heat dissipation for maximum consistency over time. The installation is particularly simple thanks to the drilling template on the wooden package and the lightweight of the speaker. Optional swivel brackets are available on request if the column has to be oriented horizontally.
Safe connections
The plastic cap/shield on the bottom-end of the column makes the connections safe and stable. Two balanced inputs are available for independent wiring of Priority and Aux audio sources. The Priority connector is available on ceramic terminal blocks with a thermal fuse for Voice Alarm applications and can be controlled by a fail-safe activation command. A remote switch-on facility is available to avoid power ON and OFF through electric switches when the columns are not part of a Voice Alarm system. By detecting the audio presence, the column can switch itself ON automatically, and then OFF after a period during which it is not used. The Data Link port allows control and monitoring from the RDNet Network, while the monitoring port can be used for ‘faulty’ remote indications. AC and DC Power supply connections are on top of the column, protected by a plastic cover. Connectors are VDE type for AC and ceramic terminal blocks for DC.
NETWORKED CONTROL AND MUCH MORE
RDNet is an advanced platform for integrated monitoring and control of sound systems - from small live and installed setups to massive arena systems. Based on a robust networked architecture, RDNet combines system control, line array design, and comprehensive audio measurements into a single powerful software package.
Engineers and technicians can intuitively manage every device on the network, from individual components to multiple groups. The platform provides full DSP control of compatible devices, with flexible configuration tools for perfectly tuning the system response at maximum speed. Users have real-time access and oversight of all key settings from a centralized interface.

Works great for sound deadening install!
Size: 3 Pack
I recently put Kilmat in my van I am converting. I thought I wouldn't need to get rollers to install the sound deadening mat in my van but I ordered these anyway. Why not, 3 rollers under $20.00 and I could return them if I didn't like them. Well I ordered this roller set. I was able to put the mat on and smooth it with my hands but these rollers really helped flatten out the sound mat to get better adhesion, especially where I overlapped the seems. The rollers were more necessary than I thought. They are very sturdy and work well. They do not feel cheap and I actually liked them quite a bit. The rollers have smooth function and leave little lines in the mat where I used them. This was very handy as it let me know where I had already used them. It was nice having 3 sizes. The big roller did not fit in some of the curved areas, so I used the smaller rollers. These will work well with sound mat that is thicker than the Kilmat as well. If you are installing sound deadening mat, you should purchase these. I saw other rollers that were more money and didn't have multiple sizes. This was a good purchase. I will try to add a picture to help with visualization purposes soon.

These mat rollers do a terrific job and worth more than the listed price.
Size: 3 Pack
This product is AWESOME!! to be sure. The 3 sizes you will come to appreciate, as I did. They have some 'heft' to them, and the ribbed rollers are far superior to the flat rollers. I just finished installing sound/thermal mats 'under' the rear speaker shelf of my '71 spiffy GTO. Tomorrow, I expect to do under the rear seat, and I am sure happy that I have three different size quality rollers. Buy these, you can't go wrong.

High quality tools
Size: 3 Pack
These are real nice. Pretty heavy and work well. Not some light weight junk tool. I’d definitely recommend these for ….. well I was sound deadening my car, but yes these were worth the money and will last me years if I ever have to get another set.
