The AS40L is a compact 4-channel portable lighting dimmer designed for theatrical, worship, educational, entertainment, and live event applications requiring reliable control of conventional lighting loads. With a capacity of 600 watts per channel and a maximum total load of 2400 watts, the AS40L provides flexible dimming in a portable format suitable for small productions, performance spaces, houses of worship, schools, and temporary lighting systems.
Key Features
The AS40L can be controlled through an external LMX-compatible lighting console or operated independently using its eight built-in chase patterns. This stand-alone capability allows the dimmer to produce automated lighting sequences without requiring a separate controller, making it useful for smaller lighting setups, displays, and simple performance applications.
Its relay mode allows selected channels to operate as non-dim on/off outputs when proportional dimming is not required. The portable design also allows the dimmer to be positioned closer to the connected fixtures, helping simplify load-cable routing in temporary and performance lighting environments.
Designed for straightforward operation and dependable conventional lighting control, the AS40L combines portable four-channel dimming, LMX-128 compatibility, relay operation, and stand-alone chase capability in a compact unit.
