eMotimo spectrum ST4

A new class of motion control

We are tremendously proud to introduce spectrum. We have already had a great response from the community to spectrum’s early access form so far, thank you! Did you know we assemble and test every unit in our shop in California before they go out the door? Learn more in our spectrum product video below:

spectrum ST4 Hardware Map

#1 Spectrum ST4

Spectrum ST4 controls and powers all 4-axis of motion at the same time.

#2 PS4 controller

The PS4 controller is included in every spectrum purchase. This control is great for wirelessly controlling 4 axis of motion precisely, intuitively, and simultaneously.

#3 Arca compatible L-brackets

To mount your camera to spectrums arca compatible tilt clamp, you will need to first mount your camera to an arca compatible L-bracket.

#4 Arca compatible clamps, ballheads, or monopod heads

Spectrums base comes with an arca plate mounted to the pan axis. You will need to lock it down by using an arca compatible clamp on your tripod or slider. For greater adjustability, mount spectrum to a ballhead or monopod head. These are great if you’ve moving up a slope on your slider and need to level spectrum, if you want to raise your spectrum up to avoid any interference, or for leveling on a tripod.

#5 Focus Fz & Integrated L-Bracket

Mount focus Fz to a 15mm rod. If you pick up our integrated L-bracket this is included and mounts to the end of the L-Bracket.

#6 spectrum ST4 / Shark Bundle

Mount your spectrum directly the the carriage on your shark slider and have spectrum control your linear motion.

#7 Tripod

Mount spectrum for panning and tilting to a tripod using an arca compatible clamp.

#8 eMotimo cart

Mount spectrum to the eMotimo cart by using a monopod head or ballhead.

Your PS4 controller connects to spectrum using the bluetooth dongle. Make sure this dongle is fully inserted before connecting your remote. Extra dongles can be found here.

#4 SD card: Firmware

An SD card is included in every spectrum ST4 purchase. Download new firmware from our site here, copy onto this card, insert into spectrum, and power on your unit to update your firmware.

Supports payload of



spectrum uses an OLED display for its outstanding viewing angles, superior sunlight readability, and low energy consumption. spectrum’s OLED is designed to work well in the field. Shooting in low light conditions? Each pixel is individually lit, which helps to save energy and reduces the cast light when compared to a backlit display. In addition, the display will be bright in cold temperatures that make typical LCD screens unreadable.

Screen Cover

spectrum’s OLED sits behind a scratch resistant, UV coated screen protector. While not indestructible, the material won’t shatter, crack or chip on impact like glass or some plastics and is recessed for additional protection. The screen will not discolor over time and is designed to keep your spectrum display looking beautiful.

controller: DualShock®4

spectrum will be controlled with the Sony DualShock4. We needed analog inputs and low latency, 2-way communication to deliver a solution that would truly be up to the task of controlling multiple axes during real-time, high-speed and VFX shots in an intuitive way. The Sony DualShock 4 has all of this and more. Loaded with over a dozen buttons, 6 analog inputs, a multi-touch, clickable track pad, vibration and light feedback, in a comfortable, ergonomic platform, we could not be more excited about the possibilities for spectrum!
