Product Overview
The Lightware MMX8x8-HDMI-4K-A-USB20 is a standalone 8x8 HDMI matrix switcher with integrated USB 2.0 peripheral switching, designed specifically for Unified Communications conference rooms and hybrid meeting spaces. It combines eight independent HDMI inputs and outputs with a USB 2.0 layer that switches four USB peripherals across four USB host computers at full 480Mbps data speed. The built-in Event Manager automates room behavior — detecting connected devices, switching signals, and preparing the room for the next meeting — without requiring a separate control processor for common operations. Target keywords: Lightware MMX8x8 HDMI USB 4K matrix switcher conference room, 8x8 HDMI matrix with USB peripheral switching, AV over HDMI matrix USB 2.0 Cisco integration.
Product Description
The MMX8x8-HDMI-4K-A-USB20 addresses the specific requirements of modern conference rooms where participants may connect personal laptops and need USB peripherals — webcams, speakerphones, multitouch panels — to switch simultaneously with the video signal. The USB 2.0 layer provides switching of four external USB peripherals to four independent USB hosts at the full 480Mbps USB 2.0 data rate, a capability unique in this class of AV matrix switcher.

The USB 5V Host Detect function triggers Event Manager actions when a USB cable is connected — for example, automatically switching USB devices to the most recently connected laptop. USB Disconnect capability solves the specific Cisco Room Kit Mini and Touch 10 compatibility issue where the touch panel becomes locked in USB webcam mode. Four plus two balanced bidirectional 5-pole Phoenix audio ports enable audio embedding and de-embedding at any point in the signal chain.

Key Features
- 8x8 HDMI matrix routing — eight independent HDMI inputs to eight HDMI outputs, 4K UHD support
- Full USB 2.0 switching at 480Mbps — 4 USB peripherals switchable to 4 USB host computers
- Separate USB 2.0 host layer — USB switching operates independently from video switching for flexible room configuration
- Camera powering via USB-A — 1000mA output on one USB-A port for powering connected cameras
- Built-in Event Manager — rule-based room automation detecting USB connection, signal presence, GPIO events
- USB 5V Host Detect — triggers auto-switching when a USB device is connected
- USB Disconnect function — resolves Cisco Room Kit Mini and Touch 10 USB webcam lock-up issues
- Cisco VC room integration — native Cisco video conferencing room workflow support
- 4K UHD HDMI support — 4K@30Hz 4:4:4 / 4K@60Hz YUV 4:2:0, up to 9Gbps
- Balanced analog audio I/O — 4+2 bidirectional 5-pole Phoenix connectors
- Advanced EDID management — per-port factory, custom, and transparent EDID emulation
Typical Applications
- Hybrid conference rooms with BYOD laptop USB peripheral sharing
- Cisco-based collaboration rooms with USB webcam management
- Unified Communications conference rooms
- Training rooms requiring USB device and video switching

Frequently Asked Questions
- Does USB switching follow video switching automatically?
- USB and video can be configured to switch together or independently via the Event Manager. In a BYOD conference room setup, the unit can automatically switch USB peripherals (webcam, speakerphone) to the laptop that last connected its USB cable, while video switching operates on separate logic.
- Is this unit compatible with Cisco Room Kit systems?
- Yes. The MMX8x8-HDMI-4K-A-USB20 includes Cisco VC room integration and specifically addresses the Cisco Room Kit Mini and Touch 10 USB webcam lock-up issue via the USB Disconnect function. Lightware's Cisco Room Configuration Wizard is also compatible.
- What is the USB 5V Host Detect function?
- USB 5V Host Detect monitors the 5V power line on USB connections and triggers Event Manager rules when a USB cable is connected or disconnected. This enables automatic switching logic based on physical USB connection events, not just video signal detection.
- What USB device types are supported?
- Any USB 2.0 device is supported, including webcams, speakerphones, multitouch displays, USB HID devices (keyboards, mice), and USB storage at full 480Mbps data speed. USB 3.0 devices will connect but operate at USB 2.0 speed.
- Can a single USB camera power multiple rooms?
- No. Each USB-A port connects one peripheral to one of four switching paths. For multi-room USB distribution, multiple nodes or a different AV architecture is required.
