fos/4 fixtures are designed and made in the ETC factory in Wisconsin, USA. But if you need more than fixtures, we’ve got you covered. fos/4 was designed to work with a full system of ETC products. Click below to read more about our consoles, apps, rigging, and other fixtures.

Over a decade of research has been realized in the fos/4 panels. It’s time to give your viewers the most realistic environments and skin tones possible. Why fix in postproduction what you can realize in production? fos/4 is available in both a tunable white light Daylight HDR array and a full-colour Lustr X8 array.

Intuitive UI

The user interface was designed with the cinematic workflow in mind. Features are simple and intuitive without compromising efficiency. The four backlit encoders change colours to correspond to the attributes they control on the screen. Even new users can quickly and accurately adjust settings.

Colour control

With fos/4 you have the option to change your fixture’s default philosophy. When working with additive colour, the fixture often decides how to mix the colour requested. There are many different options. Traditionally fixtures choose to mix the brightest version of the colour you’re trying to make. While this gives you intensity, it does not give you quality light. Aiming for quality may mean a noticeable decrease in intensity. We’re now letting you decide what you want to see. Use the tune functionality to choose brightest or best spectral.

Wireless control

Near field communication (NFC) enables you to push and pull information including fixture setup using ETC’s Set Light app from your mobile phone or tablet, even when the fixture isn’t powered.

Or use City Theatrical’s Multiverse wireless DMX control with your console. Broadcast as many as 10 universes of DMX from a single transmitter without excessive radio energy.

13-55 degree zoom

A true Fresnel with LED capabilities, fos/4 Fresnel has zoom control from either the front or the back of the fixture. Adjust the beam then use barn doors or other accessories to control the edges.

Deep Red

With the addition of a deep red LED, we render skin tones, sunsets, and moody saturated scenes better. We’ve reached further into the corners of the CIE colour space to grab the deepest red — a red that is essential to accurately capture the warm glow of firelight, romance at sunset, the most nuanced skin tones, and the truest whites.

Predictable nuanced colour from reality, to the camera, to the screen.
