The Splitter Duo Arma is a rugged, all-weather DMX splitter and signal combiner built for professional outdoor and architectural lighting networks. With its IP65-rated metal housing, it ensures stable DMX signal distribution in harsh environmental conditions while maintaining full electrical protection and flexibility for diverse installation scenarios. Whether used in architectural lighting, entertainment setups, or urban installations, the Splitter Duo Arma reliably manages and distributes DMX signals across multiple lines, offering both AC and DC power options depending on system requirements.
One of its key advantages lies in solving the most common lighting control challenges encountered in complex DMX installations. Short circuits and interference are among the most frequent causes of failure in lighting networks, and the Splitter Duo Arma addresses these issues with 5000-volt galvanic isolation on every port. This isolation prevents overvoltage damage and ensures that interference or faults on one line do not affect the rest of the system. RDM functionality enables the splitter to exchange bidirectional communication with connected fixtures, allowing technicians to receive real-time feedback on fixture status and diagnostics directly through the network. For installations using fixtures that do not support RDM, this feature can be easily disabled via internal DIP switches, preventing compatibility issues and keeping signal flow consistent.
Power flexibility is another defining strength of the Splitter Duo Arma. The unit can operate on both AC (100–250 V, 50/60 Hz) and DC (9–36 V) power supplies, making it adaptable to a variety of site conditions. The DC variant is particularly valuable for remote installations or portable setups where grid access is unavailable, allowing operation from batteries or low-voltage power systems. With a maximum power consumption of only 5 watts and a durable internal fuse, the splitter maintains stability even in areas prone to voltage fluctuations, safely tolerating voltages up to 305 V without damaging connected equipment.
Configuration is simple and reliable through onboard DIP switches located inside the sealed housing. This allows users to quickly define input/output modes and disable RDM where necessary. LED indicators provide instant visual confirmation of DMX signal presence and activity, streamlining field setup and troubleshooting. The device can function in two primary configurations: as a single splitter with one input feeding five outputs, or as two independent splitters each distributing one input to two outputs. This dual-mode operation makes it a versatile signal management tool capable of adapting to different installation architectures.
The Splitter Duo Arma’s mechanical design reinforces its long-term durability. The IP65-rated duralumin housing provides complete protection from dust, small particles, and low-pressure water jets, making it suitable for open-air environments such as parks, bridges, and architectural facades. Its fanless construction eliminates the need for ventilation openings, preventing the ingress of dust, smoke, or moisture. This sealed design not only enhances reliability but also gives the unit a vandal-resistant quality, allowing it to perform continuously in demanding public or industrial environments. Durable metal cable glands maintain secure connections even under vibration or exposure to the elements.
Operating within a temperature range from -40°C to +70°C and tolerating up to 100% relative humidity, the Splitter Duo Arma is engineered for dependable performance in virtually any climate. Whether installed in a freezing northern city or a humid coastal region, it continues to distribute clean DMX signals without degradation. The compact 129 × 56 × 118 mm housing allows for flexible mounting on flat or vertical surfaces using clamps or brackets, accommodating both temporary and permanent setups.
Compatible with DMX512 and RDM (ANSI E1.20) protocols, the Splitter Duo Arma refreshes data at a rate of 44 Hz and includes input/output configurations ranging from one to three inputs and two to five outputs, depending on the selected operating mode. Terminal block connectors provide reliable electrical contact and easy field wiring during installation.
In professional use, the Splitter Duo Arma has become a dependable choice for a broad range of lighting environments. It excels in architectural facade illumination, networked lighting in parks or landscapes, and installations across bridges, landmarks, and public art structures exposed to harsh weather conditions. It is equally at home in entertainment applications such as outdoor events, touring productions, and festival lighting systems requiring weatherproof DMX signal management.
Backed by CE and RoHS certification and a 36-month warranty, the Splitter Duo Arma embodies a balance of reliability, resilience, and simplicity. Its combination of galvanic isolation, RDM support, and dual power options ensures stable communication across lighting networks, while the sealed, maintenance-free housing guarantees uninterrupted performance through years of intensive use in any outdoor or semi-protected environment.
