The DVI-D splitter with audio and HDCP from BlackBox, type AVSP-DVI1X4, is designed for precise duplication of an HD video signal and a stereo audio input to four separate screens. The device is designed for use in professional environments where reliable and distortion-free signal transmission from one source to multiple display devices is required. The splitter operates with Single-Link DVI-D signals and supports maximum resolutions up to Full HD (1920 x 1080), UXGA (1600 x 1200), and WUXGA (1920 x 1200), with the actual resolution depending on the quality and length of the DVI cables used and the connected AV device.

Applications

The splitter is suitable for various application fields, including retail and corporate digital signage, broadcast rooms and studios, process control, engineering, healthcare, R&D imaging, classrooms, training rooms, government command centers, and temporary installations at trade shows. In these scenarios, simultaneous playback of video and audio signals on multiple displays is required, with support for HDCP-protected content, such as from Blu-ray players or other sources, being a central requirement.

Features and Equipment in Detail

The splitter features a DVI-D input and a 3.5 mm stereo audio input, each distributed to four identical outputs. The outputs consist of four DVI-D connectors and four 3.5 mm stereo audio outputs. Signal transmission occurs without attenuation or distortion, preserving the source image quality. Compatibility with EDID-capable displays enables optimized video output, as the splitter detects the EDID data of the connected displays and forwards it to the graphics card of the source device, ensuring correct adjustment of resolution and image parameters.

Technology Explained Simply

The splitter operates using Single-Link DVI-D technology, designed for digital video signal transmission over DVI cables. HDCP compatibility ensures that protected content, such as from Blu-ray players or streaming sources, is correctly reproduced. The integrated LED indicator shows signal activity at individual outputs, with a dual-color LED indicating operational status (power supply and video signal). If the input signal is lost, the splitter automatically switches to an energy-saving mode to minimize power consumption.

Compatibility and Accessories

The splitter is cascadable, allowing the number of outputs to be extended by linking multiple units. The 4-port version is 48,3 cm ( 19 inch ) rack-mountable, with rack brackets available as an optional accessory. The 8-port version includes rack brackets in the delivery scope.

Installation and Mounting

Installation requires no additional software or interface cards. Simply connect the source device and displays to the appropriate splitter connectors and power on the device. Signal distribution starts automatically. The device dimensions are 4.4 cm height, 22 cm width, and 13.5 cm depth. Power supply is via an AC input of 100–240 VAC, 50–60 Hz, with the splitter providing an output of 9 VDC, 0.6 A. Maximum power consumption is 4.1 W.

Operational Advantages

The splitter offers simple, reliable, and maintenance-free signal distribution. The combination of DVI video and stereo audio transmission enables complete playback of multimedia content. HDCP support expands usability to protected content, while EDID support ensures optimal display quality. The integrated LED indicator facilitates diagnosis of signal issues, and the energy-saving mode reduces power consumption when inputs are inactive. The 3-year Double Diamond™ warranty provides additional operational security.
