4K 8X8 HDMI Matrix Switch with IR, RS-232, and IP Control


Additional information


The 4K matrix is an 8×8 cross-point switch in a compact 1-RU enclosure. It supports HDMI resolutions up to 4K @ 30 Hz 4:4:4 and 4K @ 60 Hz 4:2:0. It also supports HDCP 2.2 and 1.4, 3D, deep-colour. PCM, Dolby, DTS, and HD audio standards. The matrix intelligently calculates EDID for each input based on the EDID of the connected sinks.

Users are able to save and recall multiple matrix routing configuration PRESETs. HDMI outputs can also be blanked. The matrix includes a two-line character LCD on its front panel in order to display the current video routing and to facilitate creating or recalling Presets.

The HSM-88-4K matrix is ideal for conference rooms, multimedia presentations, digital signage, houses of worship, and many other settings.

The Hall Technologies Experience

Our engineers have designed this product to be as intuitive to operate as possible. For example, the control commands employ simple English syntax. Want to Connect Video of output 5 to input 1? the command is simply CV5,1. How about connecting all outputs to input 1? CV*,1 (for those of you that remember DOS)!

Want to make ties (video routing) from front panel? The system does not care whether you start by pressing an input or an output button first. If you press an output button, it lights up along with the input that it is currently routed to, and you simple select a different input. Conversely, if you press an input button first,  any or all outputs that it is routed to will light up, and you can simply select other outputs to send that input to.

EDID management is another powerful feature of this matrix switch. You can select the EDID for each input from a list of 15 internal “canned” EDIDs, or you can use the EDID from any monitor connected to the outputs. Alternatively can even have the matrix compute the EDID for each input based on the capabilities of all the monitors that it is being routed to in order to get the best image with highest resolution possible. For example, say you are routing an input to three 4K TVs, then the EDID of that input will have 4K as a supported resolution. Now, if you decide to send that video to a 4th TV that only supports 1080p, instead of getting a blank screen, the matrix will re-compute the EDID to specify 1080p as the max supported resolution. If you remove the 1080p TV from that group, the EDID will revert back to 4K.
