BlackBox VSP-HDMI1X2-4K 1X2 HDMI splitter, 4K content_copy

The HDMI 4K Splitter from BlackBox, model VSP-HDMI1X2-4K, is designed for distributing an HDMI signal from a single video source to two separate HDMI displays. The device is conceived for professional applications where lossless transmission of audio and video data at resolutions up to 3840 x 2160 (UHD) is required. The function of the HDMI splitter enables simultaneous playback on multiple screens, while maintaining signal quality throughout the entire transmission length. The automatic EDID copying function ensures that the display properties of the connected monitor are automatically transmitted to the source, eliminating the need for manual settings. This is particularly advantageous when integrating into Digital Signage systems, presentation environments, or AV installations, where quick setup and reliability are paramount.

Applications

The splitter is designed for professional applications in the field of Full HD and 4K video transmission. It is especially suitable for digital signage concepts, conference rooms, training environments, or retail spaces where multiple screens must be supplied with the same content simultaneously. Support for HDCP (High-bandwidth Digital Content Protection) ensures compatibility with protected content, such as that found in Blu-ray players or streaming services. The 3D support extends the application range to applications requiring stereoscopic display. Cascadability allows multiple splitters to be linked, increasing the number of controllable displays beyond eight, which is beneficial for larger installations.

Functions and Equipment in Detail

The device features one HDMI input (female) and two HDMI outputs (female), enabling signal distribution to two receivers. Automatic signal amplification adjusts signal strength to ensure reliable transmission over longer distances without compromising image or audio quality. The integrated EDID copying function handles communication between source and display, allowing configuration without manual intervention. The indicators consist of a red LED for power supply and EDID configuration, as well as two green LEDs indicating the status of the two outputs. This visual feedback simplifies troubleshooting and daily operation.

Technology Explained Simply

The splitter operates with a TMDS clock rate of 300 MHz, enabling the transmission of high-resolution video in 4K quality. The maximum resolution of 3840 x 2160 pixels (UHD) is supported by the hardware technology, with sufficient data rate to maintain signal integrity. Power supply is provided via an external power source delivering 9 to 12 V DC at a current consumption of 220 mA. The metal housing offers mechanical stability and is suitable for wall or rack mounting, facilitating integration into existing infrastructures. Operating temperature ranges from 0 to 40°C, with storage temperature ranging from -20 to 60°C, and relative humidity up to 90% (non-condensing).

Compatibility and Accessories

The splitter is compatible with lockable HDMI cables from Black Box (model VCL-HDMIL), ensuring a secure and stable connection. Using lockable cables reduces the risk of signal loss due to loose connections. Cascadability allows multiple splitters to be connected to increase the number of controllable displays. Certifications CE, RoHS2, and UL confirm compliance with European and international safety and environmental standards. TAA compliance (Trade Agreements Act) is also provided, which may be relevant for public contracts in certain markets.

Mounting and Installation

The device is designed for wall or rack mounting, allowing flexible integration into existing systems. Installation is a plug-and-play solution, requiring no additional configuration. The connectors are standard-equipped with HDMI connectors (female), enabling connection with common HDMI cables. Dimensions are 2 cm height, 15.6 cm width, and 6.5 cm depth, ensuring a compact footprint.

Advantages in Operation

Operation of the splitter is simple and does not require special expertise. Automatic functions such as EDID copying and signal amplification minimize error susceptibility and ensure reliable signal transmission. The combination of compact design, metal housing, and professional functionality makes the device a robust solution for use in commercial and industrial environments. The 3-year Double Diamond™ warranty underscores the product’s reliability.
