Extron DA4 RGBHV | High-Resolution Video Signal Distributor

The Extron DA4 RGBHV is a high-resolution, high-bandwidth video amplifier distributor. It is specifically designed for AV integrators, control centres and corporate environments seeking impeccable signal quality. Furthermore, it offers superior operational versatility by sending a single analogue video source to multiple screens or projectors in parallel. This professional-grade unit from the renowned Extron brand incorporates precision analogue circuitry that allows complete control over signal routing. Moreover, its hardware architecture guarantees clean and ultra-stable data transmission, ensuring professional-grade performance that meets the most demanding high-fidelity video standards.

High-Fidelity Dynamics and Signal Compensation

What sets the Extron DA4 RGBHV device apart is its ability to amplify and split complex video signals without introducing noise or degrading the image. Thanks to its front-panel adjustment controls, the operator can keep attenuation levels under control. Consequently, it protects the signal against losses in brightness or sharpness caused by the use of long runs of coaxial cable. The inclusion of gain control and peaking facilitates immediate, real-time optimisation of sharpness. Furthermore, its professional BNC connections allow the distributor to be easily adapted to composite video, S-video, component (YUV) or full RGBHV signals.

Technical Specifications

• Distribution Configuration: Amplifier distributor with 1 input and 4 independent outputs.

• Compatible Formats: Full support for RGBHV, RGBS, RGsB, component (YUV), S-video and composite video signals.

• Professional Connectivity: All input and output ports use female BNC connectors.

• Equalisation controls: Integrated front-panel controls for gain and peaking (to compensate for long cable runs).

• High Bandwidth: Optimised performance with high bandwidth to maintain the integrity of high-resolution computer graphics.

• Chassis format: Sturdy half-rack metal frame, ideal for installation in equipment cabinets or control racks.

• Catalogue Status: Classic equipment featuring tried-and-tested analogue technology, in high demand for maintenance and replacement in existing fixed installations.

Key Features

• Lossless Signal Splitting: Splits the original signal into four different outputs whilst maintaining the same video voltage amplitude at each output.

• Active Cable Compensation: The peaking adjustment restores the high frequencies lost over long distances. It is therefore an essential tool for large auditoriums or control rooms.

• Video Format Flexibility: By supporting separate, composite or ‘Sync on Green’ synchronisation signals, it adapts instantly to any computer or traditional broadcast source.

• Rugged Industrial Construction: Its Extron-reinforced chassis prevents external electromagnetic interference. This ensures optimum signal purity.

• Quick Rack Installation: Its compact size means it can be grouped alongside other units from the same brand within a minimal rack space, facilitating neat and tidy maintenance.

In conclusion, the Extron DA4 RGBHV amplifier distributor is an essential tool for broadcast studios and presentation rooms that need to replicate high-resolution video signals with absolute fidelity. By incorporating active amplification, gain controls and robust BNC connectors, it ensures a technically sound visual output and a perfectly defined signal. In short, it is a robust and reliable piece of equipment, designed to operate 24/7 with minimal maintenance in any professional audiovisual infrastructure.
