DMX512 and RDM Control with On-Unit Addressing

This DMX decoder supports both DMX512 and (Remote Device Management) protocols. While standard DMX512 provides reliable one-way communication between the controller and connected devices, RDM adds two-way communication. DMX consoles can then read device information and remotely set the decoder's DMX start address.

This simplifies system configuration and ongoing maintenance, which is especially helpful for larger installations where manually accessing every decoder can be time-consuming.

For added convenience, the decoder also features a built-in digital numeric display with control buttons. This way, you can configure the DMX start address directly on the unit whenever you need to. The output can be set to operate in 1-, 2-, or 4-channel mode. This makes it suitable for a variety of constant voltage LED lighting applications without requiring different decoders.

4 Channel Constant Voltage Output for RGB and RGBW LED

This decoder is designed specifically for constant voltage LED lighting. This pairs well with 4-channel RGB and RGBW LED strip installations operating on 12V to 48V DC systems.

A constant voltage LED strip light must always be paired with a compatible constant voltage decoder. This is to ensure that the operation is kept safe and performance is consistent. That’s why choosing the correct output type is essential.

The unit delivers up to 8A per channel on 12V or 24V DC systems, and up to 6A per channel on 36V or 48V DC systems. Depending on the input voltage, it provides a maximum total output power of 384W at 12V, 768W at 24V, 864W at 36V and up to 1152W at 48V.

This broad voltage compatibility allows greater flexibility when designing or upgrading lighting systems.

Flicker-Free Dimming for Camera and Retail Spaces

In retail displays, showrooms, and environments where photography or video recording takes place, smooth, flicker-free, and consistent dimming is essential. That’s why this decoder offers selectable PWM (Pulse Width Modulation) frequencies ranging from 250Hz up to an impressive 32,000Hz.

Higher PWM frequencies help minimise visible flicker on camera, producing cleaner footage and creating a more professional appearance under artificial lighting. With this feature, you can choose the most suitable setting for your installation.

The decoder also supports selectable 8-bit (256 levels) and 16-bit (65,536 levels) grey scale modes. This means exceptionally smooth transitions even in lower brightness settings.

Finally, the addition of selectable logarithmic and linear dimming curves enables the lighting response to be tailored to different installation requirements and preferences.

Stand-Alone RGB and RGBW Programmes Without a DMX Signal

Not every lighting installation requires a dedicated DMX controller running at all times. For smaller projects or applications where simple lighting effects are sufficient, this decoder includes built-in RGB and RGBW programmes, as well as a convenient 4-channel dimmer mode. These functions can be selected directly using the buttons on the unit. In other words, this decoder operates independently and does not require a DMX signal.

For straightforward colour-changing displays, static lighting scenes or installations where the lighting behaviour rarely changes after setup, stand-alone operation like this is ideal.

Although this is not intended to replace the advanced functionality of a dedicated lighting controller, it at least provides a versatile alternative for applications where simple, reliable lighting control is sufficient.

Flexible DMX Wiring and Signal Inputs

Thanks to its wide range of DMX signal input options, installing the decoder into an existing lighting system is easier. The decoder supports connection through a green screw terminal, XLR3 male and female connectors, and an RJ45 port. This gives you the flexibility to work with different cable types and wiring preferences. With this feature, you can easily integrate the system into both new and existing constant voltage LED installations.

If the setup calls for daisy-chaining, the decoder can also support that by allowing multiple units to be connected together as part of a larger DMX network. Just note that a suitable DMX signal amplifier is needed for systems with more than 32 decoders or for installations with particularly long cable runs.

A 90 to 120-ohm terminal resistor is also recommended at the end of each DMX line to improve signal integrity.

Built to Last with Full Protection and a 5-Year Warranty

The decoder is built for dependable day-to-day operation. As an added peace of mind, it features automatic overheat and short-circuit protection. These help safeguard both the unit and the connected lighting system.

The compact aluminium housing measures 175mm x 80mm x 45mm, allowing it to fit easily into tight, hidden indoor installation spaces (comes with an IP20 rating).

The decoder is also certified to CE, RoHS and FCC standards and complies with EN IEC 55015 and EN IEC 61547, so you’re sure that it meets recognised safety and compatibility requirements.

Finally, every unit is backed by a 5-year warranty and distributed by a supplier with more than 14,000 five-star reviews on Google, Trustpilot and Reviews.io. This gives you the added confidence in the quality and reliability of the fitting.
