Doug Fleenor Design Marconi LV – Wireless DMX Receiver with 4-Pin Power Input.

The Marconi LV (Low Voltage) is a compact wireless DMX receiver designed to deliver reliable DMX512 signal distribution in theatrical, architectural, and entertainment applications where cabling is challenging. It receives one full universe (512 channels) of DMX512 data wirelessly using W-DMX technology and outputs it via a single 5-pin DMX connector. The Marconi LV is powered through a 4-pin XLR connector, accepting low-voltage input (9–24V DC), making it versatile for integration with existing low-voltage systems or an optional external power supply. Its small size and robust performance make it ideal for controlling DMX fixtures like the Martin Atomic 3000 or Elation Platinum Beam 5R Pro in stage setups managed by controllers like the ETC Express 48/96 or CueServer Pro CS-800. 

• Power Input: Features a 4-pin female XLR connector (Neutrik D-1 series) for low-voltage power, using pins 1 (ground) and 4 (+V) for 9–24V DC input at 300mA minimum. A 4-pin male XLR “power through” connector passes all four pins to support daisy-chaining with compatible low-voltage devices (e.g., color scrollers or LED fixtures). 
• Wireless Technology: Utilizes W-DMX protocol on a 2.4 GHz frequency, with a range of up to 1500 feet (line-of-sight, depending on environment), ensuring reliable DMX transmission. 
• DMX Output: One 5-pin female XLR connector, delivering a full DMX universe (512 channels) for controlling lighting fixtures or effects like the Antari AF-3X Fan. 
• Indicators: Green LED for signal strength and red LED for DMX data, providing visual feedback on wireless connection and data transmission. 
• Antenna: 2 dBi omnidirectional antenna (optional high-gain antenna available for extended range). 
• Configuration: Simple push-button pairing with W-DMX transmitters (e.g., Marconi TX or SP), with channel selection to avoid interference. 
• Construction: Compact aluminum enclosure (6.5” L x 2.5” W x 1.5” H), designed for truss mounting with rigging like the CM Lodestar 1/4-ton hoist or surface installation. 
• Applications: Ideal for temporary stage setups, outdoor events, or venues requiring cable-free DMX distribution, such as theaters, concerts, or architectural installations.
