Designed for AV environments with extremely high image quality requirements such as conference halls, lecture theaters, and exhibition spaces, the VE1843A is a high-performance HDBaseT 3.0 solution that integrates both transmitter and receiver functionality into a single unit. It delivers uncompressed True 4K HDMI extension with zero latency over a single Cat 6a cable*.



Uncompromised True 4K Precision with Zero Latency

The VE1843A leverages the latest HDBaseT 3.0 technology to extend uncompressed True 4K @ 60 Hz (4:4:4) signals up to 100 meters (and 1080P up to 150 meters) with zero latency. By supporting HDR10+, Dolby Vision, and HDCP 2.3, it ensures that highfidelity visuals are delivered with mission-critical precision, making it the ideal choice for environments where real-time response and image integrity are non-negotiable.



Adaptive 2-in-1 Design for Maximum Deployment Flexibility

The VE1843A eliminates the need for separate hardware. Its unique 2-in-1 architecture allows a single unit to be configured as either a transmitter or a receiver to fit any AV architecture. This flexibility helps system integrators streamline inventory and reconfigure setups for point-to-point extensions or complex matrix systems with much greater agility.



Unified Single-Cable Signal Distribution for Streamlined Integration

The VE1843A consolidates uncompressed video, bi-directional IR, RS-232, Gigabit Ethernet, independent audio, power and USB 2.0 into one Cat 6a cable. This integration ensures seamless connectivity for peripherals like touchscreens and cameras, making it the perfect foundation for modern collaborative environments.



Independent Audio Routing with Bi-Directional PoH Efficiency

The VE1843A empowers users with independent audio embedding and de-embedding, providing the freedom to route sound to match any environment. To simplify installation, bi-directional PoH allows the unit to draw power from either the source or display side, effectively removing the need for extra power outlets. Enclosed in a fanless fin heat sink for silent, stable cooling, the VE1843A is built for reliable, continuous professional use.
