BlackBox AC1056A-4 VGA Broadcaster, 4-channel content_copy

The Compact VGA Video Splitter from BlackBox, type AC1056A-4, is a 4-channel distributor for VGA video signals, enabling a single video signal from a computer to be transmitted simultaneously to four separate monitors. The device is designed for use in environments where simultaneous display of content at multiple locations is required, such as presentations, training sessions, trade show booths, or retail stores. Distribution occurs via VGA connectors, with signals capable of being transmitted up to a distance of 64 meters, allowing flexible placement of monitors. The unit is compatible with various monitor types, including VGA, Super VGA (SVGA), and Multisync monitors, ensuring clear, sharp images without visible quality loss.

Applications
This splitter is particularly suitable for applications where multiple people need simultaneous access to the same screen content. These include training events, public information systems, retail environments, and industrial facilities where information is displayed at workstations on the factory floor, while the central CPU is located in a separate room. The ability to cascade the unit expands the number of possible outputs, allowing more than four monitors to be connected when multiple splitters are operated in series.

Functions and Features in Detail
The device features one input with an HD15 connector (VGA female) and four outputs, also equipped with HD15 connectors. Signals are transmitted via the VGA protocol, with a maximum bandwidth of 350 MHz. This enables high image quality and supports resolutions up to 1920 x 1440 at a refresh rate of 70 Hz. The unit includes an automatic power-saving function that activates when the incoming VGA signal is lost, reducing power consumption. Installation is simple: VGA cables are connected to the appropriate ports, the device is powered on, and video playback begins immediately. The package includes VGA cables for input and output connections.

Technology Explained Simply
The splitter’s technology is based on signal amplification and distribution. The incoming VGA signal is received, amplified, and simultaneously transmitted to the four outputs. The 350 MHz bandwidth ensures that even high-resolution signals are transmitted without distortion or delay. The maximum transmission distance of 64 meters accounts for signal quality and cable losses, with the recommendation to use high-quality VGA cables to optimize performance. Power supply is provided via an external power adapter, accepting input voltages from 100 to 240 VAC at 50 to 60 Hz, and delivering an output of 5 VDC at 2 A, ensuring reliable operation of the device.

Compatibility and Accessories
The splitter is designed for use with standard VGA connections and supports all common VGA and SVGA monitors. The cascading function allows for expansion of the number of outputs by connecting multiple splitters in series. Additionally, 2-channel and 8-channel models are available, with the 8-channel model offering a bandwidth of 300 MHz. Compatibility with various monitor types and support for high resolutions make this device a flexible solution for diverse application scenarios.

Mounting and Installation
Mounting requires no special tools or technical expertise. The unit is simply connected to a power source, and VGA cables are plugged into the corresponding sockets. Cabling is done using the VGA cables included in the package. The unit can be placed on a desk or mounted in a rack, with dimensions of 4.1 cm height, 8.4 cm width, and 6.9 cm depth. The weight is specified as 0.3 kg.

Operational Advantages
Operating the splitter is simple and maintenance-free. The automatic power-saving function reduces power consumption when no signal is present. High bandwidth and support for high resolutions ensure clear image reproduction. The ability to cascade the unit provides a scalable solution for applications with multiple monitors. The inclusion of VGA cables simplifies installation and reduces the need for additional purchases. The 3-year Double Diamond™ warranty provides additional security for operation.
