DMA2X3 6-Way DMX Signal Splitter | 12–48V DC DMX512 Distributor

Overview

The DMA2X3 is a professional 6-way DMX512 signal splitter designed to distribute, isolate and stabilize DMX signals across multi-branch lighting networks. With one DMX input, one DMX loop (thru) and six fully buffered outputs, the DMA2X3 ensures reliable DMX512 communication in large installations. Supporting 12–48V DC input and built-in electrical isolation, it is ideal for architectural lighting, commercial spaces, stage lighting and any installation requiring long-distance or multi-branch DMX distribution.

Key Features

• 1 DMX input, 1 DMX thru (loop), and 6 independent DMX outputs
• Supports DMX512/1990 protocol
• 12–48V DC wide input voltage range
• Fully isolated and buffered outputs for maximum signal stability
• Prevents signal loss, interference and voltage drop in large DMX networks
• Protects against ground loops and electrical noise
• Each output is separately amplified and regenerated
• Built-in indicators for power and DMX signal status
• Supports long-distance DMX transmission
• Ideal for multi-branch installations and complex lighting networks
• Compact metal housing for reliable heat dissipation

Technical Notes

• DMX input can be looped through to an additional splitter or DMX device.
• Each of the six outputs provides a newly regenerated DMX signal.
• Opto-isolation helps eliminate noise caused by mismatched grounding.
• The splitter improves DMX reliability, especially in long-distance cable runs.
• A 120Ω terminator may be used at the end of each DMX output chain if required.
• The device does not generate DMX; it distributes the incoming signal.
• Compatible with DMX controllers, DMX dimmers, decoders, amplifiers and fixtures.

Wiring & Installation Notes

• Connect the DMX controller to the DMX input port.
• Use the DMX thru port to continue the DMX chain or feed another splitter.
• Connect DMX devices to the 6 independent output ports.
• Use standard DMX512 twisted-pair cable for best performance.
• Power the device using a regulated 12–48V DC power supply.
• Terminate the last fixture in each DMX branch with a 120Ω resistor.
• Install in a dry indoor environment (IP20).
• Mount in a control cabinet, rack, enclosure or flat surface.

Applications

• Architectural LED DMX lighting
• Stage lighting and event installations
• Commercial and hospitality lighting networks
• DMX control system expansion
• Building façade lighting
• Museums, malls, hotels and entertainment venues
