The Lightware MX-TPS-OB (MX-TPS-OB-P) is an 8-channel twisted pair output board for long-distance AV signal transmission. It provides HDMI 1.4, audio, Ethernet, and RS-232 extension over a single CAT5/6/7 cable up to 100 m in HDBaseT™ mode and 170 m in Long Reach mode (Full HD 1080p). Resolutions up to 4K UHD and 48-bit colour depth are supported, including 120 Hz 3D signals. Optional digital S/PDIF or analog stereo audio add-ons allow flexible audio embedding and de-embedding. Advanced professional features such as HDCP enable/disable, Pixel Accurate Reclocking, Advanced EDID Management, and Frame Detector ensure reliable, high-quality AV operation. Remote powering is available via the PoE add-on.

Available in two variants:

• MX-TPS-OB: Base model, standard input board with HDMI 1.4, Ethernet, RS-232 extension
• MX-TPS-OB-A: Same as base model with analog audio.

Application Examples 

Live Events / Rental

Corporate / Enterprise

Stage-to-FOH runs: Extend HDMI video, embedded audio, RS-232 and Ethernet to LED processors or projectors over a single CAT cable (100 m 4K / 170 m 1080p). Processor feeds: Drive multiple remote TPS receivers from the MX frame; test patterns simplify pre-show verification. Audio workflows (OB-A): De-embed S/PDIF/analog to mixers or PA while keeping HDMI audio to displays. Tour-ready backbone: Long-reach mode and EDID/HDCP tools ensure stable playback from varied sources.

Meeting room distribution: Send HDMI + control to remote rooms over existing CAT cabling; carry Ethernet to endpoints. Training & capture: Feed projectors/displays while providing separate audio to DSP or recorders (OB-A). Conference & VC: Embed or replace program audio into HDMI for consistent room routing (OB-A). Control rooms: Deliver video + RS-232/IR/GPIO to operator consoles with built-in diagnostics for quick fault-finding.

Scenario	Recommended Model	Why
Long-distance HDMI + control to remote displays (no special audio needs)	MX-TPS-OB	Cost-effective HDMI + Ethernet + RS-232 extension with embedded HDMI audio over CAT.
Live events requiring audio breakout to mixers/PA	MX-TPS-OB-A	De-embed to S/PDIF/analog while keeping HDMI audio to screens; level controls for quick gain matching.
Corporate rooms with DSP / assistive listening	MX-TPS-OB-A	Analog I/O with embedding/re-embedding integrates cleanly with DSPs and ALD systems.
Education / training rooms on shared CAT infrastructure	MX-TPS-OB	Reliable 4K@30 / 1080p Long-Reach delivery plus Ethernet and control over a single cable.
Control rooms / operator consoles	MX-TPS-OB or OB-A (if audio routing needed)	EDID/HDCP tools, test patterns and frame diagnostics ensure predictable endpoint behavior; choose OB-A when independent audio feeds are required.
