Supporting 4K UHD at 30Hz RGB 4:4:4 or 60Hz YCbCr 4:2:0, it handles eight independent HDMI sources to eight HDMI outputs with full HDCP compliance and 3D capabilities. The Event Manager feature makes this unit particularly effective for conference rooms, training rooms, and boardrooms where automated switching based on AV system state is required. Key search terms: Lightware MMX8x8 HDMI 4K matrix switcher, 8x8 HDMI switcher with event manager, 4K HDMI matrix with room control.
Product Description
The MMX8x8-HDMI-4K-A is a 2RU standalone matrix switcher delivering eight HDMI inputs and eight HDMI outputs with full 4K/UHD support and HDCP compliance. The built-in Event Manager provides rule-based room automation — responding to signal presence, RS-232 or IR triggers, or GPIO events — without requiring an external control processor for basic switching scenarios.

Four plus two balanced bidirectional 5-pole Phoenix audio ports enable analog audio embedding and de-embedding at any I/O point, supporting installations where audio must be broken out to a separate DSP or amplifier. Control options include RS-232, Ethernet, and USB, plus RS-232 and IR injection ports for sending commands to downstream endpoints. The Cisco VC room integration feature and advanced control feature pack for third-party video conferencing make the MMX8x8-HDMI-4K-A well suited to modern Unified Communications environments.

Frequently Asked Questions
- Does the MMX8x8-HDMI-4K-A support HDMI 2.0?
- The unit supports 4K UHD signals up to 30Hz at full RGB 4:4:4, and up to 60Hz at YCbCr 4:2:0 chroma subsampling. For full 4K/60Hz 4:4:4 at 18Gbps, consider the Lightware MX2 series.
- Can the Event Manager replace a dedicated control processor?
- For basic switching automation — such as auto-switching on signal detection or triggering RS-232/IR commands on input change — the Event Manager operates independently without external control hardware. Complex multi-system logic still benefits from a dedicated processor.
- How is audio handled?
- The unit provides 4+2 balanced bidirectional 5-pole Phoenix audio ports that support both analog audio embedding into the HDMI stream and de-embedding from HDMI outputs to analog audio systems.
- What control systems are compatible?
- The unit exposes RS-232, Ethernet (TCP/IP), and USB control ports, making it compatible with Crestron, AMX, Extron, and Q-SYS processors. Lightware also provides LDC software for direct PC management.
- Is this unit compatible with Cisco room systems?
- Yes. The MMX8x8-HDMI-4K-A includes a Cisco VC room integration feature pack and is compatible with Lightware's Cisco Room Configuration Wizard for simplified Cisco codec integration.
