4×4 HDMI 2.0 Matrix Switcher

The BG-4K-44MA routes four HDMI 2.0 sources to four displays with full 4K60 4:4:4 and HDR pass-through. HDCP 2.2 compliance protects premium content across all ports. Independent audio de-embedding sends digital S/PDIF or balanced audio to separate zones. Front-panel buttons, IR remote, RS-232 and TCP/IP web GUI give installers flexible control options.

Replaces single-output splitters or basic switchers

A single-output splitter forces every display to show the same source; this matrix lets each screen pick any input independently. Auto-downscaling on every output allows legacy 1080p displays to stay in the system without extra converters. The jump is worth it when a venue needs simultaneous, different content on multiple screens with centralised audio routing.

Verify source and display capabilities before

Confirm each source outputs HDMI 2.0 at 18 Gbps and that target displays accept 4K60 4:4:4 or 1080p. Check that cable runs stay within HDMI 2.0 distance limits for the chosen resolution. Ensure the 24 V locking power supply and included IR receiver cable reach the intended mounting location. RS-232 and TCP/IP integration require an available serial port or network connection.

Questions about this item

What rack space does the 18×8×2 in chassis require?

The unit measures 18 inches wide, 8 inches deep and 2 inches high, so it occupies a single 2U shelf or rack tray.

Which cable is used for the RS-232 link and what common mistake should be avoided?

Use the supplied 1.5 m male-to-female serial cable; the frequent error is plugging it into a USB port instead of a true RS-232 port.

When should the 24 V 3.75 A locking power adapter be replaced?

Replace the adapter if the locking barrel becomes loose, the unit loses power intermittently, or the output voltage drifts below 24 V under load.
