25G-8HDMI2-A3-OB provides fully transparent HDMI 1.4 connectivity to the latest high-end digital sinks including the Audio Return Channel and 3D functions between the endpoints. Supports resolution up to 4096x2160@30Hz in 4:4:4 mode or 3840x2160@60Hz in 4:2:0 mode (4:2:0). The new 300 MHz board supports the latest 3D formants as well as HD multichannel audio.

25G-8HDMI2-A3-OB has 8 HDMI connectors with an additional analog Phoenix audio connector for each HDMI port. Each output is standard compliant and has individual EDID Management.

25G-8HDMI2-OB can de-embed IEC 60958-1 and IEC 61937 audio from the HDMI signal to the Return audio layer. It can also embed audio signal from the Forward audio layer to the output HDMI signal.

The A3 add-on has bi-directional configurable Phoenix connectors. The digitized audio from the add-on can be embedded either to the output HDMI signal or to the Return audio layer. Moreover, IEC 60958-1 audio either from the HDMI signal or the Forward audio layer can be routed to the add-on output. Furthermore, the output board can route the ARC audio to the Return audio layer.

The audio options of the HDMI output board are software configurable on a per-port basis.
