24‑48 Channel DMX Dimmer Console,Optical‑Isolated Output,Master‑Slave Expandable for Stage Lighting

24‑48CH Manual DMX Dimmer Console,Flash Buttons,LCD & Power‑Fail‑Memory for Theatre Shows

This 24/48 channel master‑slave dmx dimmer console is 19‑inch rack‑mount manual dimming‑control hardware built for theatre performances, live‑stage shows, auditorium installations, church venues and mobile event‑rental projects across Europe and North America. Optimized for traditional manual‑style lighting operation, this DMX512/1990‑standard dimmer desk is widely adopted by theatre technicians and fixed‑venue integrators for straightforward channel‑by‑channel brightness adjustment.

Two hardware variants are supplied:24‑channel and 48‑channel models. The 24‑channel unit provides direct access to all channels via physical faders. The 48‑channel version uses Page‑A and Page‑B toggle buttons to switch two banks of 24‑channel groups, achieving full 48‑channel control within same cabinet footprint. All DMX outputs are optically isolated, which helps suppress ground‑loop interference and protects internal circuits from signal‑line surges in complex venue power environments.

Rich manual‑operation functions streamline live‑show workflows. Every channel is fitted with independent fader and flash button; flash function triggers instant full‑bright output while pressed and restores fader value upon release. Fine‑plus and fine‑minus buttons together with dial‑enter wheel allow precise incremental value modification and preset management. Six submaster groups can be saved by holding dial‑enter wheel and pressing submaster button for quick recall of pre‑set lighting looks. Clear LCD screen displays real‑time channel values and working parameters for onsite reference.

Master‑slave network linkage via RJ45 ports enables multi‑console channel expansion. The 24‑channel variant can expand maximum up to 96 channels, while 48‑channel unit supports expansion up to total 192 dimming channels. RS232 communication port allows integration with third‑party building central‑control systems to trigger saved submaster presets. Power‑fail memory preserves all stored submaster data, avoiding repeated manual reprogramming after accidental power interruption.

Both variants share identical mechanical specifications. Dimension measures 482×265×75 mm and net weight is 2.65 Kg, fitting standard 19‑inch equipment racks and flight‑cases. Wide‑range AC88‑256V 50‑60Hz power input adapts to most European and United States mains‑grid conditions. This console is designed for indoor‑only deployment. Operators shall follow standard DMX wiring practice and apply DMX terminator at the end of fixture signal chain. Featuring optical‑isolation protection, expandable master‑slave architecture and central‑control compatibility, this dimming console is a reliable manual‑control solution for theatre and performance‑lighting projects throughout Europe and North America.
