Lightware UMX-HDMI-140-Plus UMX Series Switcher for VGA, DVI-I, HDMI and DisplayPort with Audio embedding - 91560003

Product Overview

The Lightware UMX-HDMI-140-Plus is a compact multi-input presentation switcher that accepts VGA, DVI-I, HDMI, and DisplayPort sources and routes them to a single HDMI output, with built-in audio embedding for analog audio inputs. It is engineered for professional AV installations where a variety of legacy and modern source types must be connected to a single display or AV distribution system. The UMX-HDMI-140-Plus is commonly deployed in corporate meeting rooms, training environments, and education spaces as a reliable multi-input HDMI switcher with broad signal compatibility.

Product Description

The UMX-HDMI-140-Plus accepts four video inputs — VGA, DVI-I, HDMI, and DisplayPort — and switches between them to a single HDMI output, making it a practical solution for environments where multiple source types must share a common display. An integrated audio embedder accepts an analog stereo input and embeds it into the HDMI output stream, supporting sources such as laptop headphone outputs, conferencing systems, and document cameras without external audio processors. The unit supports resolutions up to 1080p60 across all input types, with the internal scaler normalizing inputs to the selected output resolution. Front-panel buttons provide manual source selection, while the RS-232 and LW2 control protocol interfaces enable integration with room control systems. The compact half-rack form factor allows installation in rack enclosures, credenzas, or under-table cable management systems. The UMX-HDMI-140-Plus includes Lightware's EDID management, ensuring consistent source handshake regardless of which input is active or what display is connected to the output.

Frequently Asked Questions

Can the UMX-HDMI-140-Plus handle 4K source signals?

The UMX-HDMI-140-Plus supports resolutions up to 1080p60 and WUXGA. If 4K sources must be connected, the unit will accept the signal but scale the output to the maximum supported resolution. For native 4K switching, consider Lightware's HDMI 2.0 matrix or UMX series with 4K support.

Does the audio embedding work with all four inputs?

The analog audio input embeds into the HDMI output regardless of which video input is selected. It is always active and mixed with any embedded digital audio present in the selected HDMI or DisplayPort source, depending on configuration.

Can this unit be controlled by a Crestron or AMX control system?

Yes. The RS-232 interface and LW2 protocol command set are fully documented. Crestron and AMX drivers are available, and the unit responds to standard ASCII commands for source selection, querying, and status reporting.

Is auto-switching (auto-detect of active source) supported?

Yes. The unit can be configured in auto-switching mode, where it monitors input ports for active signals and switches to the most recently connected active source automatically, without operator intervention.

What type of power supply does this unit require?

The UMX-HDMI-140-Plus uses an external 12V DC power adapter, which is included in the box. The unit does not support PoE power input.

Can I connect a VGA source without audio to the HDMI output and still have audio?

Yes. When a VGA source (which carries no digital audio) is selected, the analog audio embedded via the 3.5mm jack is routed into the HDMI output, providing a complete audio-video signal to the display or downstream AV system.

Is this suitable for permanent installation or is it better for temporary setups?

The UMX-HDMI-140-Plus is designed for permanent installation. Its rack-mount form factor, control system integration, and EDID management make it appropriate for fixed meeting room, classroom, and presentation suite deployments. For questions on installation planning, contact Creation Networks.
