1U Rack‑Mount DMX Merger,8‑Input,HTP‑LTP Mode,2048‑Ch /512‑Ch for Stage Lighting

Professional DMX Merger‑Distributor,Super‑Drive Output,LED Status Indicator for Live Shows

This 1u rack mount 8 input dmx512 signal merger is 19‑inch 1U rack‑mount DMX‑512 signal‑combining hardware built for theatre productions, large‑scale live‑concert tours, TV broadcast‑recording studios and mobile event‑rental projects across Europe and North America. This signal‑processing unit solves multi‑source‑control requirements, merging DMX signals sent from several lighting consoles or playback devices into unified output groups for downstream lighting‑fixture systems.

Two hardware‑selectable channel configurations are available via front‑panel DIP‑switches. 8‑in‑4‑out mode delivers four independent output groups for total 2048 DMX channels. Under 8‑in‑1‑out mode, all eight inputs merge together, and four physical output ports duplicate identical 512‑channel signal. Operators can toggle merging logic between HTP (Highest Takes Precedence) and LTP (Latest Takes Precedence) according to show‑control workflow. In HTP mode, the highest numerical channel‑value among competing inputs gets transmitted. LTP mode selects channel value coming from the most‑recent‑modified signal source.

One‑hundred‑percent full electrical‑isolation is implemented for every input‑output interface. Surge‑protection circuit is integrated for each signal port to resist transient‑voltage spikes in complex venue‑power environments. Every DMX output port features super‑drive capability to offset signal attenuation over long DMX cable runs. Dedicated LED lamps give visual feedback: red indicators monitor incoming input‑signal presence, green LEDs display real‑time output‑signal status for fast on‑site diagnosis.

This compact 1U height hardware fits standard 19‑inch equipment racks. Wide‑range AC88‑256V 50‑60Hz power input adapts to various mains‑grid standards throughout European nations and United States. The unit meets CE, UL and GB 7000.15‑2000 safety‑related specifications. Physical dimension measures 482 mm × 175 mm × 45 mm with net‑weight of 1.65 kilograms.

This indoor‑only rack‑mount device must be kept dry and away from strong magnetic‑field interference. Operators shall set DIP‑switch modes before power‑on deployment and follow standard DMX wiring practice with terminators at signal‑chain end. Supporting multi‑source‑signal combination, flexible HTP‑LTP logic and full‑port isolation, this DMX‑512 signal merger provides reliable multi‑console signal‑combining solution for complex entertainment‑lighting projects throughout Europe and North America.
