Introduction

Key Digital’s KD-MLV4x2Pro is a seamless multi-format video matrix with UHD/4K resolution

up-scaling, multi-view window processing, audio de-embedding, independent audio from

video matrix selection, and HDCP 2.2 compliancy. The HDMI and HDBaseT output are

independent in full-screen and quad screen modes. KD-X222PO Rx HDBaseT extender

receiver is included and powered from the matrix.

KD-MLV4x2Pro is designed to ﬁt a wide variety of professional video installation and live-

event needs. It is ideal for digital signage, video wall, conference & board room, huddle

spaces, home theater, and bar/restaurant applications.

Quick Setup Guide

1. Begin with the main unit, Rx unit, and all input/output devices turned off and power cables removed

2. Connect Video and Audio Sources to the desired KD-MLV4x2Pro input ports

3. Connect HDMI output ports to a display/sync device using Key Digital HDMI cables and audio devices to the audio outputs

4. Connect the Rx unit’s HDMI output a display/sync device, and use a CAT5e/6 cable to interconnect the Rx and KD-MLV4x2Pro’s HDBaseT ports.

5. Connect power to the KD-MLX4x2Pro and power on, then repeat for source devices, then display devices.

6. Choose desired screen layout via front panel buttons, IR, web control interface, RS-232 or TCP/IP

» a. Some features not available in all layout and control types. Please refer to following

sections for more information on controllability and setup for each control type.

IR Emitter Control

When using an IR Emitter / IR Extender (sold separately), the IR Emitter must be mounted over the IR Sensor on the front of the KD-MLV4x2Pro. One end of the cable is connected to the IR Receiver/ Master Controller / IR Extender / IR Connecting Block, while the other end is mounted over the IR Sensor of the KD-MLV4x2Pro.

Serial IR Control

As a more robust alternative to optical IR, KD-MLV4x2Pro may also be controlled via hard-wired IR. Use a 3.5mm Male Mono plug with the IR Signal carried on the tip of the connector.

Rack Mounting

Secure the rack ears to each side of the KD-MLV4x2Pro with the supplied hardware then fasten the unit to the rack rails with the included machine screws.
