The state-of-the-art transducers developed for the VSA II offer the highest intelligibility and a 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 reduce the size of the overall system.

The powerful multichannel DSP controls each of the eight Class-D 50W power amplifiers, which can drive the eight transducers with 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 VAC modes and in 24 VDC as a backup power source. Every model includes active protection against overvoltage and overcurrent. 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. It's also ideal for voice-alarm applications.

The unobtrusive and robust aluminum cabinet blends seamlessly in any architecturally sensitive environment. 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 light weight of the speaker. Optional swivel brackets are available on request if the column has to be oriented horizontally.

The plastic cap/shield on the bottom 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/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 when it is not being 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.

RDNet is a proprietary protocol for RCF products that provides straightforward monitoring and intuitive control of the audio system down to every single device/object. Each device has its DSP, giving the possibility to address specific presets or parameter changes to single or groups of objects. The beam steering configuration is fast and precise as well as the equalization preset adjustments. The RCF RDNet is the perfect tool to help designers and installers configure a VSA system setup in any venues.

The optional VSA Smart RC (VSA-RC) is an easy way to control the VSA speakers through the VSA Remote app available on iOS or Android. The following data are configurable on each VSA through the optional remote control:

 

• Selection of the proper beaming and tilting/steering configuration
• Delay in meters
• Voice/music equalization
• Polarity
• Mute
• Volume
• Standby and configuration-lock

The I/R receiving diode is recessed, and its directivity coverage has been narrowed to receive I/R commands just from the dedicated remote located in front of the column axis. Thanks to this, if two columns are close to each other, there is no risk of two receivers being driven at the same time.
