ATEN VE1843A True 4K HDMI / USB HDBaseT 3.0 Transceiver with PoH content_copy

The VE1843A was designed for AV environments with extremely high image quality requirements, such as conference rooms, lecture halls and exhibition spaces.
It is a powerful HDBaseT 3.0 solution that combines both transmitter and receiver functions in a single device.
It enables uncompressed True 4K HDMI extension with zero latency over a single Cat 6a cable*.
Uncompromising True 4K precision with zero latency
The VE1843A uses the latest HDBaseT 3.0 technology to transmit uncompressed True 4K signals at 60 Hz (4:4:4) up to 100 meters (and 1080p up to 150 meters) with zero latency.
With support for HDR10+, Dolby Vision and HDCP 2.3, it ensures that high-resolution images are transmitted with maximum precision – making it the ideal choice for environments where real-time responsiveness and image integrity are essential.
Adaptive 2-in-1 design for maximum deployment flexibility
With the VE1843A, there is no need for separate hardware. Thanks to its unique 2-in-1 architecture, a single device can be configured as either a transmitter or receiver, adapting to any AV architecture.
This flexibility helps system integrators optimize inventory and adapt configurations for point-to-point extensions or complex matrix systems with significantly greater flexibility.
Unified signal distribution over a single cable for optimized integration
The VE1843A combines uncompressed video, bidirectional IR, RS-232, Gigabit Ethernet, independent audio, power and USB 2.0 over a single Cat 6a cable.
This integration provides seamless connectivity for peripherals such as touchscreens and cameras, making it the perfect foundation for modern collaborative environments.
Independent audio routing with bidirectional PoH efficiency
The VE1843A enables independent audio embedding and de-embedding, giving you the flexibility to adapt audio to any environment.
To simplify installation, bidirectional PoH allows the device to receive power from either the source or the display, eliminating the need for additional power outlets.
The VE1843A is housed in a fanless finned heat sink enclosure that provides quiet and stable cooling and is designed for reliable, continuous professional operation.
