introduction

The KD-MLV4x4Pro is a matrix switcher device with multi-view video processing tailored for a variety of environments, from sports and gaming caves to corporate AV setups.

Its capabilities extend to bars & restaurants, house of worship, entertainment centers, museums, and E-Sports.

This matrix processor elevates the viewing experience thanks to user-friendly control, powerful features, and intuitive connectivity.

The Ultimate Picture-In-Picture Experience

The KD-MLV4x4Pro's multi-view tiling processor empowers users to display up to four video sources simultaneously on a single screen. This offers a selection of default and customizable layout presets.

This feature enables content layering, allowing users to adjust bezel frame width and color to suit their preferences. The video processor effortlessly handles 4K / UHD content at 60fps input, ensuring smooth transitions between sources when all outputs are in full-screen mode.

Independent Audio Routing Capabilities

In addition to its video processing capabilities, the KD-MLV4x4Pro boasts advanced audio matrixing features.

It supports independent audio routing with de-embedding ports for analog balanced/unbalanced and digital optical connections. This flexibility allows users to select audio sources even in multi-view mode.

The audio processor accommodates surround formats up to 5.1 Dolby® / DTS™ for theater applications.

Connectivity and Integration

The KD-MLV4x4Pro is designed to easily integrate into new and existing setups. It offers optional 4K down-conversion for compatibility with legacy displays or projectors.

Additionally, the device accommodates IR input from control systems, extending control functionality to the displays connected through KD-EXMLVRx units. This enhances overall system management and control capabilities.

Advanced Compatibility and Control

The KD-MLV4x4Pro comes equipped with advanced standards compatibility. It supports HDCP 2.2 and facilitates EDID handshaking for communicating resolutions and audio formats to connected sources.

KD-MLV4x4Pro can be controlled from any smartphone, tablet, or PC from its user-friend web page, or using the Key Digital iOS app in addition to a professional control system.

Features

  • Multi-view Tiling Processor: Simultaneously watch multiple sources on a single screen
