Product Description
Overview
The KUPO DX-404 is a compact DMX (Digital Multiplex) dimmer pack for small lighting systems that still need proper addressing, dimming response, preview, and load-friendly warm-up behavior. It is sized for truss hanging or desktop use, making it practical when a full rack dimmer would be too large for the job.
Why It Matters
Small rigs often fail at the awkward middle ground: more control than a household dimmer, less space than a dimmer rack. DX-404 gives technicians four-channel style portability with 5 A per-channel capacity, start-address control, and output-status preview in a package that can live near the fixture position.
Key Features
- 5 A per channel and 15 A total output support compact theatrical, venue, and service rigs
- DMX-512 control with XLR 3-pin and 6P4 C RJ11 signal connections gives more wiring flexibility in small systems
- C3 dimming curve and 256-step resolution provide smoother level changes than simple on/off control
- Warm-up setting from 0-6 % helps protect lamp loads and extend bulb life during repeated operation
- Auto frequency tracking and channel output preview make setup easier when the pack is used away from the main console
Applications
Use it for small venues, rehearsal rooms, touring practicals, temporary stage positions, service benches, and compact truss rigs that need portable DMX dimming without a rack system.
Compatibility
Designed for DMX-512 control systems and lamp loads within 5 A per channel, with power options for AC 100-120 V or AC 200-240 V at 45-63 Hz.
Frequently Asked Questions
Can this replace a full rack dimmer?
Only for smaller loads. DX-404 is intended for compact systems, with 5 A per channel and 15 A total output rather than high-capacity rack dimming.
Why does the warm-up setting matter?
The 0-6 % warm-up setting keeps a small amount of power available to the lamp load, which can reduce stress during repeated cueing.
Can I put it on truss instead of a table?
Yes. The product description describes DX-404 for truss hanging or desktop operation, so it can sit close to the fixtures when the setup calls for it.
