Each input is optically isolated to protect connected lighting control systems from electrical interference and faults. Its rack-mountable 1U design, front-panel XLR connectors, and rear hardwire connections make it well-suited for permanent installations in entertainment, architectural, and event production environments. The unit includes a universal AC power supply (100–240 V to 12 VDC) and is built for reliable performance in complex control setups.\u003c\/p\u003e\n\u003ch4\u003eKey Features:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003eMulti-Input Capacity: 8 × 5-pin XLR male inputs to 1 × 5-pin XLR female output for versatile control configurations.\u003c\/li\u003e\n\u003cli\u003eHTP Merging Logic: Ensures the highest active DMX value takes priority across all inputs.\u003c\/li\u003e\n\u003cli\u003eOptical Isolation: Protects all inputs against interference and voltage surges.\u003c\/li\u003e\n\u003cli\u003eDual Connection Options: Front-panel XLR and rear-panel hardwire terminals for flexible wiring.\u003c\/li\u003e\n\u003cli\u003eRack-Mount Design: 1U (19\") rack-mountable chassis for easy integration into control racks.\u003c\/li\u003e\n\u003cli\u003eUniversal Power Supply: Operates on 12–24 VDC with included 100–240 VAC to 12 VDC adapter.\u003c\/li\u003e\n\u003cli\u003eDurable Construction: Built for professional use with robust housing and dependable connectors.\u003c\/li\u003e\n\u003cli\u003eStandards Compliance: Fully compliant with DMX512 control protocol.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eThe DMXSM-H81 offers dependable, interference-free DMX signal merging, making it an essential tool for multi-console or redundant control setups in professional lighting systems.\u003c\/p\u003e","brand":"Leviton","offers":[{"title":"Default Title","offer_id":49105256841472,"sku":"DMXSM-H81","price":1277.43,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0388\/5331\/2557\/files\/DMXSM-H81_FRONT_WithReflection_1000.jpg?v=1785543631","url":"https:\/\/alotechparts.com\/products\/dmxsm-h81-leviton-dmx-signal-management-merger","provider":"Alo Tech Solutions","version":"1.0","type":"link"}
