hdmi mixer

Bandwidth ranges vary by model — common examples include 18 Gbps devices up to higher-capacity units (e.g., 40 Gbps). Supported standards typically include HDMI 2.0 (with HDCP 2.2/1.x) on mid-range units and HDMI 2.1 (with HDCP 2.3 on some high-end models) where listed.

Some matrices offer independent EDID control and EDID management via DIP switches or built-in controls, letting you present compatible EDIDs to sources. Many also support downscaling (for example, downscaling a 4K source to 1080p) to ensure compatibility with lower-resolution displays.

Some HDMI switchers/mixers include multi-channel audio mixers that can de‑embed and re‑embed HDMI audio (examples include 12-channel digital mixers). Video features found on advanced units can include manual T-bar control, program/preview or multiview, picture‑in‑picture, chroma/green‑screen keying, and other live-production effects.

Frame buffers or time-base correctors (TBCs) buffer input signals so sources don’t need to be genlocked. This buffering smooths switching between unsynchronized inputs by aligning frames and avoiding glitches during transitions.

Dual-function units can act as splitters—sending one input to multiple displays—or as switches—selecting between multiple inputs to send to one output. Typical examples include devices that duplicate one source to two displays or switch between two inputs.

Some units include a built-in, automatically adjusting amplifier or signal regenerator that strengthens the HDMI signal, allowing you to extend beyond the normal ~25-foot range for high-speed (1080p) runs. These repeaters/regenerators improve signal integrity over longer cable runs.
