Overview

The DX-1220 is a 12-channel DMX dimmer pack in a 19" 4U rack chassis, built for venues that need serviceable control of conventional tungsten and switched lighting loads. Each channel is an extractable 20 A module with its own Miniature Circuit Breaker (MCB), giving technicians a practical way to maintain a rack without removing the entire dimmer from the electrical bay.

Why It Matters

A venue dimmer rack has to keep working through long seasons, not just pass the first install. Pull-out modules, per-channel protection, software output limiting, emergency scene memory, and self-test mode all point toward the same goal: faster service and fewer dark circuits when the room is active.

Key Features

• 12 channels at 20 A maximum output per channel support conventional theatrical loads and architectural circuits in one rack unit.
• Individual extractable modules with dedicated MCB protection make field service more practical than replacing or removing the full rack.
• DMX-512 control plus DC 0-10 V analog input supports modern consoles and legacy backup or retrofit systems.
• Emergency scene memory continues a stored output if the DMX signal drops, keeping the space lit during control failure.
• Automatic thermal management starts the fan at 37 °C, cuts output above 63 °C, and restarts below 60 °C.

Additional Technical Notes

• Power Input: AC 100-240 V, 45-63 Hz, 3 phase 4 wire, other spec upon request

Applications

Designed for theatres, concert halls, hotel ballrooms, conference centers, museums, galleries, cinemas, department stores, nightclubs, and other venues running conventional dimmed or switched lighting circuits.

Compatibility

Accepts DMX-512 over 5-pin XLR and DC 0-10 V analog input over 15-pin D-sub; specify the DX-1230 instead when 30 A per channel capacity is required.
