Product Overview
What makes the ML-401104
The ML-401104 HDMI enables independent routing of four HDMI source devices to four HDMI displays. Unlike basic HDMI splitters or switches, it allows each output to display a different source or the same source simultaneously across multiple screens — without any physical cable reconfiguration.
This flexibility makes the device suitable for complex AV installations where multiple content sources need to be distributed to different viewing locations. Source devices such as computers, media players, presentation systems, and monitoring equipment can all be connected simultaneously. Each output is individually configurable, allowing operators to dynamically manage video routing based on real-time operational requirements.
The Without Auto Fall Back feature is a key differentiator for environments that require continuous display output. When the selected input signal becomes unavailable, the system automatically routes the affected output to the next available active input — with no manual intervention required. This is especially critical in control rooms, conference environments, and digital signage installations where display continuity is non-negotiable.
The ML-401104 is engineered to maintain a stable HDMI signal transmission across all connected outputs during switching operations. Internal processing prevents common HDMI issues such as signal dropouts, handshake delays, and display flickering, making the device reliable across demanding professional AV environments.

FAQs about the ML-401104
What does the ML-401104 4x4 HDMI do and how is it different from a regular splitter?
The ML-401104 4×4 HDMI lets you connect four HDMI sources and route them to four displays independently. Unlike a splitter, you are not limited to showing the same content everywhere — each screen can show a different source or the same one, depending on your setup.
How does the Without Auto Fall Back feature work in the ML-401104 HDMI?
The Without Auto Fall Back feature automatically switches to another active source if the current one stops working. This ensures your displays never go blank, which is especially important in control rooms, conference setups, or any environment where continuous display is critical.
Will switching between sources affect signal quality or cause screen issues?
The ML-401104 is designed to maintain stable HDMI signal performance, even during switching. It reduces common issues like flickering, signal dropouts, or delays, so transitions between sources remain smooth and reliable.
Can I display different content on each screen using this 4 in 4 out HDMI?
Yes, that is one of its biggest advantages. This 4-in-4-out HDMI allows each output to show a different input source, or you can choose to display the same content across multiple screens if needed.
Is the ML-401104 easy to integrate into an existing AV system?
Yes, it is built for professional setups and works well with HDMI extenders, processors, and control systems. Its compact design also makes it easy to install in AV racks or cabinets without complicating your existing setup.
Can all four sources remain connected simultaneously, or do devices need to be disconnected when switching?
All four source devices can remain physically connected to it at all times. Switching between sources is handled electronically through the switch — no physical disconnection or reconnection of cables is required. This is one of the primary operational advantages of a matrix switch compared to a standard HDMI switch.
What happens if more than one source signal drops? How does Without Auto Fall Back handle multiple simultaneous failures?
