ATEN CS1824

4-Port USB 3.0 4K HDMI KVMP™ Switch with Audio Mixer Mode

 

 

The ATEN CS1824 is a professional-grade 4‑port KVMP™ switch that empowers users to seamlessly control and monitor up to four HDMI-enabled computers using just one USB keyboard, mouse, and HDMI monitor. Designed for high-performance environments like CGI workstations, video post-production suites, engineering labs, and complex multitasking tasks, it delivers uncompromising video quality with support for up to 4K DCI (4096 × 2160 @ 60 Hz) and 4K UHD (3840 × 2160 @ 60 Hz) . This level of visual clarity ensures that detailed content—be it intricate CAD models, high-resolution footage, or large spreadsheets—can be viewed with precision and consistency.

One key advantage of the CS1824 is ATEN’s proprietary Video DynaSync™ technology. This feature accelerates display initialization and prevents booting issues when switching between systems, automatically restoring optimal resolution and refresh rates. Complementing this is the default EDID mode, which simplifies compatibility across different monitors and sources, enabling smooth power–ups and reducing display errors. Firmware upgrades via USB ensure the system remains feature-rich and secure over time.

The CS1824 includes a built-in USB 3.1 Gen 1 hub (SuperSpeed 5 Gb/s) with two fast USB-A ports, enabling the sharing of high-speed peripherals like external SSDs, audio interfaces, or web cameras among connected computers. This hub operates independently from the KVM focus, allowing users to access USB devices from one computer while controlling another—an ideal setup for multitasking workflows. Additionally, Audio Mixer Mode enables mixing of audio from any two connected systems into a single passive output, ensuring important notifications or alerts are not missed even if those systems are not in focus.

Switching between systems is versatile and intuitive: users can toggle via front-panel pushbuttons, keyboard hotkeys, mouse cursor movement (in emulation mode using supported mice), RS‑232 serial commands, and even auto-scan mode for continuous monitoring. The RS-232 interface is valuable for integrating into existing automation frameworks or custom workflows, providing centralized control and scripting options. This flexibility ensures low learning curve yet high integration potential across various operational environments.

Physically designed for desktop or rack-mounted setups, the CS1824 is housed in a rugged metal chassis and draws just 2.535 W of power at 5 V. Its compact dimensions (~27 × 8.8 × 5.55 cm) and lightweight build (~0.94 kg) make it suited to 24/7 operations without overheating or bulk. Front-panel LEDs clearly indicate active connection, USB activity, and audio status. The device supports HDCP 2.2 and HDMI 2.0 compliance, as well as high-definition audio, ensuring compatibility with modern digital media devices .

From an ecosystem standpoint, the CS1824 brings mission-critical features such as power-on detection, which automatically switches to the next active system upon shutdown, ensuring users always remain connected to an operational computer. Multilingual keyboard support enhances usability in diverse global teams or international collaborations. The firmware is upgradable via USB, and the default EDID settings ensure compatibility across different monitor brands.

In summary, the ATEN CS1824 offers a powerful, user-friendly, and future-ready KVM solution for high-resolution, multi-system environments. By combining ultra-high video quality, intelligent display management, flexible audio merging, fast USB 3.1 sharing, and robust multi-mode switching—all within a compact, robust chassis—it stands out as an ideal choice for professionals who demand efficiency and clarity in managing multiple computers. Whether in content creation, simulation labs, or control centers, the CS1824 ensures productivity is maximized without compromise.
