Lightware MMX4x2-HDMI 4x2 HDMI Matrix Switcher with Breakaway Analog Audio - 91310034

Product Overview

The Lightware MMX4x2-HDMI is a 4-input, 2-output HDMI matrix switcher with breakaway analog audio routing, designed for professional AV installations requiring flexible signal distribution in conference rooms, training facilities, and collaboration spaces. It handles HDMI signals at up to 1080p60 and provides independent analog audio routing that is decoupled from the video switching path, enabling separate audio and video source assignments on each output. The compact 1U chassis includes RS-232, Ethernet, and IR control interfaces for integration with room control systems. As part of Lightware's MMX series, it supports Lightware Control Protocol for scripted and event-driven automation in managed AV environments.

Product Description

The MMX4x2-HDMI provides a 4x2 HDMI switching matrix where any of four HDMI inputs can be independently routed to either or both of the two HDMI outputs. The breakaway analog audio feature allows the analog audio associated with any input to be routed to either output independently of the video assignment — for example, routing video from Input 1 with audio from Input 3 to Output 2. This is essential in training rooms where a local audio reinforcement system must receive audio from a different source than the display. HDCP 1.4 is supported across all paths. The unit includes balanced analog audio inputs and outputs on terminal blocks in addition to HDMI-embedded audio, providing maximum flexibility for interfacing with installed sound systems. Front-panel buttons enable manual source selection, while RS-232 and Ethernet ports support integration with control systems. The MMX4x2-HDMI operates within Lightware's LW2 control protocol environment, with configuration handled via Lightware Device Controller software.

Frequently Asked Questions

Can the MMX4x2-HDMI route the same source to both outputs at the same time?

Yes. Any single input can be mirrored to both Output 1 and Output 2 simultaneously. This is the standard configuration for a main display plus a confidence monitor or a secondary room display.

How does breakaway audio routing work in practice?

Each output has an independent audio source assignment. For example, Output 1 can carry video from HDMI Input 1 with audio from the balanced analog Input 3, while Output 2 carries video from HDMI Input 2 with audio from HDMI Input 2. All combinations are independently configurable.

Does the unit handle 4K signals?

The MMX4x2-HDMI is rated for HDMI signals up to 1080p60. It is designed for installations where display endpoints are 1080p. For 4K switching, Lightware offers higher-tier matrix products including the UCX series.

What control system protocols are supported?

The unit responds to Lightware's LW2 protocol over RS-232 and Ethernet (TCP/IP). Lightware publishes third-party drivers for Crestron (SIMPL), AMX (NetLinx), and Extron (Global Scripter). Custom control can be implemented via any RS-232 or TCP/IP capable processor.

Can I connect the balanced audio outputs directly to a mixer or amplifier?

Yes. The balanced analog audio outputs on terminal blocks are line-level signals compatible with professional audio mixers, amplifiers, and DSP systems. Verify the input impedance requirements of the downstream audio device.

Is EDID management available?

Yes. EDID can be read, copied, and emulated per input using Lightware Device Controller software. This ensures source devices output the correct resolution and audio format regardless of the downstream display's EDID.
