4x4 HDMI Matrix KVM Switch

This 4x4 HDMI matrix KVM switch routes four HDMI sources to four displays simultaneously. It supports resolutions up to 4K at 30 Hz with 8, 10 or 12 bit deep colour. Audio formats include DTS-HD, Dolby TrueHD, LPCM 7.1, DTS, Dolby AC3 and DSD. The unit is designed for conference rooms, control rooms and training environments.

Compact build with IR and RS-232 control

The chassis is described as very compact, stable and reliable. Each HDMI output can show the same or a different source at the same time. Output one provides both a 3.5 mm stereo jack and a Toslink optical port for simultaneous analogue and digital audio extraction. An IR remote and RS-232 port at 232 baud allow local or automated switching.

Replaces basic splitters and single-output switches

Unlike a simple splitter that duplicates one signal to many screens, this matrix lets each display choose any of the four inputs independently. It upgrades installations that previously needed multiple switches or manual cable swapping. The jump is worth it when you need independent routing to four displays with extracted audio and centralised control.

Questions about this item

What HDMI version and refresh rate does the 4x4 matrix support?

The switch handles up to 4K resolution at 30 Hz with 8, 10 or 12 bit deep colour.

What physical connections and power supply are required to mount the unit?

Four HDMI inputs, four HDMI outputs, a 3.5 mm stereo jack, a Toslink optical port, an RS232 port and the included US plug power adapter.

How is the matrix configured and which step is often missed?

Connect sources and displays, power the unit, then use the IR remote or RS232 at 232 baud to route each output; the EDID extractor on output 1 must be set first so all sources recognise the display capabilities.
