The VSA 850 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 8 Class-D 50 W power amplifiers, which can drive the 8 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.

Great for plants
Color: 1. Carbonized Black, Color: 1. Carbonized Black
I gave this a 4 on easy to install and sturdiness because I wasn’t able to actually drill it into the wall because of the way my apartment wall is, not this product, so I cannot speak much on those 2 fields.
However, this has found a lovely home on top of my bedroom’s radiator and it works great for my plants! It stands up straight on it’s own and I only need to place it on the radiator and do not need to tie/drill it to something else to keep it standing up. Would recommend for someone looking for a cute shelf on a counter top as well.

Light, sturdy when assembled, and just a simple elegant piece.
I have a guest bath that I have remodeled, and I wanted something understated and still elegant enough to go with my very pretty bathroom. I opted to not have a medicine cabinet put in when the house was built and have only used the under-sink cabinet for my needs. The bathroom has all new off-white paint, new oval mirror which is tiltable, new lights, new really beautiful larger cabinet, and it's all in brushed nickel. I did purchase 2 of these units and so far, have only received the "all" black. The other is black metal with white shelves. I am not sure which one I will be putting in the bathroom as yet until I see the white one that should be here any day now. Looking forward to it. It's exactly the right size, metal is very light but nice, the wood shelves are nice but there are no pre-drilled holes so you will have to figure that out and looks very easy to hang with the 4 holes in the metal parts. I believe it's a great buy for us! I will be using it for face cloths, extra hand towels, a candle or 2, a small tray for jewelry, and a picture and plant. Good to go!!

Too expensive but I love it anyway
Color: 1. Carbonized Black
Way too expensive for the quality of the "wood" but I love the way it looks and it holds all my plants 🪴
Holds securely against the wall when installed properly.

Beautiful, spacious yet compact, sturdy shelf
Color: 1. Carbonized Black, Color: 1. Carbonized Black
The only shelf I've ever bought and hung on a wall and I love this s**t. It is absolutely beautiful on the wall and you wouldn't think it could hold so much weight.
Installation was fairly easy with the use of a power drill and the included wall studs.
I use it to hold a few sketchbooks and journals, my PS4 games, and any other random stuff I like displaying. If I had more books I'd throw em on there no problem.
