SEETEC monitor ATEM215S-CO 21.5"""" W. SDI Carry-On Flight Case

SEETEC ATEM215S-CO 21.5" Full HD Broadcast Monitor – 4x3G-SDI Inputs with Carry-On Aviation Case

SEETEC ATEM215S-CO delivers a complete monitoring solution for multi-camera on-set shooting, monitoring and post production. It is a full HD broadcast carry-on monitor with robust connectivity and on-set tools, designed for film and television crews, broadcast teams and post-production environments.

21.5-inch Full HD LCD

The ATEM215S-CO features a 21.5-inch LCD panel with Full HD resolution of 1920x1080 for accurate image detail. It adopts the Rec.709 color standard to reproduce natural and clear images. The panel provides 250cd/㎡ brightness, a 1000:1 contrast ratio and a 178° wide viewing angle, so the image remains visible and consistent from varied viewing positions.

Portable Aviation Aluminum Case

The monitor ships in a portable aviation aluminum case designed for location work. The case offers dust-proof and waterproof properties as well as resistance to high temperature and corrosion. Therefore, it suits transport and use in different environments, providing safer protection for the monitor during shoots.

Quick Assembly and Tool-Free Disassembly

The ATEM215S-CO uses an innovative combined structure that enables quick disassembly and assembly without tools. As a result, you can switch between indoor and outdoor setups rapidly and reduce downtime on set.

Comfortable Handle and Butterfly Locks

The case includes a handle sized for comfortable carrying to ease movement of the unit between locations. Both the case links and the front and rear covers use butterfly-shaped locks that are durable and visually appealing, securing the monitor during transport.

Accurate Color Reproduction and Factory Calibration

The monitor uses Rec.709 professional HD color standard and built-in 3D-LUT. SEETEC applies color calibration technology with professional instrument calibration at the factory to ensure consistent color reproduction across units. This supports reliable color-critical monitoring on set and in post.

Flexible and Intuitive Button Operation

The front panel provides flexible controls for fast operation during shoots. You can switch sources with one button, set custom shortcuts, and quickly adjust brightness, contrast and volume. Backlit buttons help you identify current input and shortcuts, making the monitor easier to use in dimly lit studios or outdoor locations.

Connectivity: 4x3G-SDI Inputs and Outputs plus HDMI, RS485 and GPI

The ATEM215S-CO offers strong connectivity for multi-camera workflows. It includes 4x 3G-SDI inputs and corresponding outputs for multicamera shooting and simultaneous monitoring by multiple personnel. In addition, it provides one HDMI input, RS485 and GPI control interfaces to meet a variety of control and signal requirements.

Professional On-Set Monitoring Tools

The monitor integrates a comprehensive set of monitoring tools to improve focus, exposure and color evaluation. You can access waveform, 3D-LUT, peaking filter, histogram, vectorscope, audio meter, time code and anamorphic mode directly from the menu. These tools are selectable from the front panel and can be assigned to shortcut buttons or controlled via GPI, helping to improve on-set efficiency and post-production accuracy.

3D-LUT Support and Custom LUT Loading

The ATEM215S-CO includes 3D-LUT functionality to recreate film looks and quickly change color styles. It provides four built-in DE-log LUT options and supports loading custom .cube LUT files via USB flash drive. The monitor supports loading up to 36 custom LUTs for flexible color workflows.

HDR Monitoring

The monitor supports HDR (high dynamic range) monitoring to enhance clarity and reveal greater image detail. When HDR is enabled, you can select Gamma and Gamut settings corresponding to manufacturers such as Sony, Canon, Panasonic, Fujifilm, Bolex, RED and ARRI to match camera output profiles.

Accurate Waveform Monitoring

The ATEM215S-CO includes built-in waveform monitoring to provide broadcast-accurate technical feedback on video and audio signals. Available displays include RGB Parade, YUV Parade and Y Parade, vectorscope, histogram, audio phase and level. Functions can be opened separately or with a single key to enter full scope mode, which also supports left/right adjustment. This reduces the need for separate external scopes during live production.

Gynamic UMD (TSL 3.1/4.0 Protocol)

The monitor supports UMD using the TSL 3.1/4.0 protocol with RS485 connectivity. It allows 0–126 TSL address selection and supports up to 16 displayed characters. UMD inputs and outputs operate via the RS485 port.

Tally Lights and GPI Control

GPI control operates Red Tally and Green Tally indicators on the monitor. These tally lights notify camera operators when the camera is in recording or program state, adding a professional workflow cue on set.

Multiple Display Modes

The screen supports Full Screen, Picture-in-Picture (PIP) and Quad View to meet different monitoring needs. In PIP mode, you can adjust the size and position of the sub-window. In Quad View, the monitor can display four SDI signals simultaneously and show a 4-channel audio meter and 4 time codes.

16-Channel Audio Level Meters and Headphone Output

The monitor can de-embed audio from both SDI and HDMI. It supports up to 16 channels of embedded audio meters when using SDI and displays two channels for HDMI audio. You may select any two audio channels to output via the 3.5mm headphone jack for direct monitoring.

Custom Menu Settings and Sunshade

ATEM215S-CO provides four groups of custom menu settings which the monitor automatically saves. Therefore, your preferred settings persist after power cycles, saving setup time. The unit also includes an extended sunshade to improve screen visibility in bright environments.

Rugged Application for Various Environments

The monitor is designed to operate reliably in a wide range of locations, from cold to hot environments. As such, it is suitable for demanding on-location shoots and can handle challenging conditions.
