Distributed Dimming

  • The next generation of tungsten

    Want the benefits of distributed power control in your venue? The Source Four Dimmer™ provides convenient - yet powerful - per-fixture power control that cuts down on cabling and puts fewer demands on the infrastructure of your venue. It attaches to any conventional Source Four® unit for onboard dimming. You can order any Source Four fixture with a Source Four Dimmer lamp cap already attached, or retrofit existing fixtures by ordering a lamp kit.

    Silence is golden

    ETC designed the Source Four Dimmer using ES (Electronic Silent) technology for noise-free operation, making it the right choice for concert halls, opera houses, theaters and other venues that demand a silent environment. The dimmer works without fans and produces no filament buzz, for noise levels of 0dBA at one meter. That means you can connect Source Four Dimmers to all of the Source Four fixtures you have on your rig and still hear a pin drop. 

  • Logical power-system design for hybrid rigs

    As venues move toward a hybrid lighting approach - combining conventional fixtures, LED luminaires and other emerging technologies into a light plot - you're faced with new challenges for power system designs. Now you can send simple switched power to your lighting positions to run all of your LEDs and tungsten loads at the same time. Use your existing distributed data network to control Source Four Dimmers, LEDs and moving lights. This new power-distribution system cuts down on cabling and makes your venue more flexible with an infrastructure that can adapt to new requirements and layouts.

    Professional-level dimming

    Most distributed dimmers on the market fall short when it comes to functionality and durability. The Source Four Dimmer, however, draws on ETC's award-winning power-control expertise, and gives you professional-quality dimming with the same level of security that you get from an ETC Sensor® system… but in a distributed model! Mounted directly to the fixture, the Source Four Dimmer has onboard controls for local operation and RDM for remote setup - you can even configure your rig from your desk! It also allows you to find and set DMX addresses, change curves and receive status information. Strong and rugged, the Source Four Dimmer is designed to last, braving the rigors of everyday lighting over time.
