Important Safety Instructions

Please read and keep the information in the attached safety instructions supplied with the
product before you start using the device.

Introduction

The MMX8x4-HT400MC is a standalone matrix switcher is specifically designed for conference room environments with eight video inputs (four HDMI and four TPS) and four HDMI video outputs. 4K / UHD (30Hz RGB 4:4:4 or 60Hz YCbCr 4:2:0), 3D capabilities and HDCP are fully supported. MMX8x4-HT400MC has a dedicated Special Audio Input block with input ports for microphone and line- in. The built-in sound mixer allows free mixing of the microphone or the line- in and the de-embedded audio from one of the input HDMI signals.

The MMX8x4-HT400MC matrix is compatible with any third-party HDBaseTTM device.

HDBaseTTM and the HDBaseT Alliance logo are trademarks of the HDBaseT Alliance.

Compatible Devices

The MMX8x4-HT400MC matrix is compatible with other Lightware TPS devices, matrix TPS and TPS2 boards, 25G boards, as well as third-party HDBaseT- extenders, but not compatible with the phased out TPS-90 extenders.

The jog dial control knob can be used to navigate between the menu items or change the value of a parameter. The knob can be pressed to enter a menu or edit/set a parameter.

Mounting Options – Standard Rack Installation

Two rack ears are supplied with the product, which are fixed on left and right side as shown in the picture. The default position allows mounting the device as a standard rack unit installation.


The matrix switcher is 2U-high and one-rack wide.
The matrix switcher is 2U-high and one-rack wide.
Always use all four screws for fixing the device ears to the rack rail. Choose properly sized screws for mounting. Keep a minimum of two threads left after the nut screw.

To ensure the correct ventilation and avoid overheating, leave enough free space around the appliance. Do not cover the appliance, leave the ventilation holes free on both sides

Connecting Steps

• TPS: Connect an HDBase-TTM -compatible transmitter to the TPS input port (not PoE-compliant).
• HDMI: Connect an HDMI source (e.g. PC) to the HDMI input port.
• HDMI: Connect an HDMI sink (e.g projector) to the HDMI output port.
• RS-232: Optionally connect a serial device (e.g projector) to the 3-pole Phoenix connector to transmit RS-232 commands.
• IR: Optionally connect an infra emitter to the infra output port (2-pole Phoenix or 1/8” Stereo Jack connector) to transmit infra signal.
• LAN: Optionally connect a UTP cable (straight or cross, both are supported) in order to control the matrix switcher via the Lightware Device Controller software.
• USB: Optionally connect a USB cable in order to control the matrix switcher via the Lightware Device Controller software.
• Audio: Optionally for analog output, connect an audio device (e.g. audio amplifier) to the analog audio output port by an audio cable.
• Audio: See the Installation Guide for Connecting a Microphone section on the next page before connecting the microphone. Improper settings can cause damage.
• Audio: Optionally for audio input port: connect the audio source (e.g. media player) to the audio input port by an audio cable.
• Power: Connect the power cord to the AC power socket of the matrix unit.

Powering the device is recommended as the final step

The infrared emitter and detector units are optionally available accessories

Serial Output Voltage Levels (TTL and RS-232)

| **TTL*| RS-232
---|---|---
Logic low level| 0 .. 0.25V| 3 V .. 15 V
Logic high level**| 4.75 .. 5.0V| -15 V .. -3 V

*Using a receiver with at least 1k impedance to any voltage between 0V and 5V to get the voltages

Installation Guide for Connecting a Microphone

These settings can be done from a computer using the Lightware Device Controller (LDC) software. The application is available at www.lightware.com, install it on a Windows PC or a Mac OS X and connect to the device via LAN, USB, or RS-232.

1. Before the connection, please set these properties below:
   Port| Property| Value| Lightware Device Controller
   ---|---|---|---
   Analog audio output (BAL.OUT| Volume| -80dB and/or Mute| |
   Microphone input (MIC IN)| Volume| -80dB and/or Mute| |
   Skipping the volume or mute setting can cause serious damage in the speaker or the external sound system when phantom power is turned on!
   Phantom power| Turn off|
   Always turn off the phantom power before connecting the microphone!
   Port| Property V| Value| Lightware Device Controller
   ---|---|---|---
   Microphone input (MIC IN)| Input gain| -12dB|
   EQ (High,Hmid, Lmid, Low)| 0|
   Panorama| 0|

2. Connect the microphone.

   • In case of dynamic or wireless microphone: skip this step and follow the
     instructions with step 3.

   • In case of condenser microphone: Switch on the phantom power. Keep pressing the +48V button for more than 2 seconds to activate phantom power.
     Phantom power supplies the condenser microphone by 48V, which is necessary for normal operation. Application of the phantom power can cause damage if a dynamic or wireless microphone is connected!
     Always switch on the phantom power when the cabling and connecting are done. Do not disconnect the microphone when the phantom power is switched on!

3. Set these properties below:
    | Property| Value| Lightware Device Controller
   ---|---|---|---
   Analog audio output (BAL.OUT)| Volume| 0dB|  |
   Microphone input (MIC IN)| Volume| 0dB|  |

4. Talk to the microphone continuously. Increase the microphone input gain slowly and check the signal indicator chart. It gives a feedback about the optimal signal level.
    Make sure that the peak led (PK!) never lights up!

5. If the signal level is low, set the optimal volume on both the microphone input and balanced output channels. Always check the signal indicator chart for the optimal level!
Make sure that the peak led (PK!) never lights up! MIC input volume| Output volume
