Important Safety Instructions

Please read the supplied safety instruction document before using the product and keep it available for future reference.

Introduction
MMX8x4-HT420M is a standalone matrix switcher specifically designed for conference room environments. It has eight video inputs (4x HDMI, 4x TPS) and four video outputs (2x HDMI 2x
TPS). 4K / UHD (30Hz RGB 4:4:4 or 60Hz YCbCr 4:2:0), 3D capabilities, and HDCP are fully supported. MMX8x4-HT420M 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 audio signals from the de-embedded HDMI, the microphone or the line-in.

Factory Default Settings

0.00
Analog audio input levels| Volume (dB): 0.00; Balance: 0; Gain (dB): 0.00
Analog audio output levels| Volume (dB): 0.00; Balance: 0

Remote Powering (PoE)
The matrix is PoE-compatible (in accordance with IEEE 802.3af standard) and able to send remote power to connected TPS devices via the TPS connection (through the CATx cable). No local power adaptor is required for the connected PoE-compatible TPS extender. The PoE feature is enabled on TPS ports as factory default.

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| |
   A 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|
   A Always turn off the phantom power before connecting the microphone!

Port

| Property| Value|

Lightware Device Controller

---|---|---|---
Microphone input (MIC IN)| Input gain| -12dB| -12|
EQ (High,Hmid, Lmid, Low)| 0| -18|
Panorama| 0| L|
2. Connect the microphone.
a. In the case of dynamic or wireless microphones: skip this step and follow the instructions with step 3.
b. In case of condenser microphone: Switch on the phantom power. Keep pressed 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 the dynamic or wireless microphone is connected!
Always switch on the phantom power when the cabling and connecting have already been 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 feedback about the optimal signal level.
Take care that peak led (PK!) never lights up!

5. If the signal level is low, set the optimal volume for both the microphone input and balanced output channel. Always check the signal indicator chart for the optimal level!
   Take care that peak led (PK!) never lights up!

Connecting Steps

CATx Connect an HBase-T TM -compatible transmitter or matrix output board to the TPS input port. 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.
Audio Optionally for analog output port: 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 left, before connecting the microphone. Not proper setting can cause damage.
Audio Optionally for audio input: connect the audio source (e.g. media player) to the audio input port by an audio cable.
USB Optionally connect the USB cable in order to control the matrix switcher via the
Lightware Device Controller software.
LAN Optionally connect the UTP cable (straight or cross, both are supported) in order to control the matrix switcher via the Lightware Device Controller software.
Relay Optionally for relays: connect a controlled device(s) (e.g. a projection screen) to the relay port.
IR Optionally connect the infra emitter to the infra output port (2-pole Phoenix or 1/8” Stereo Jack connector) to transmit the infra signal.
GPIO Optionally connect a controller/controlled device (e.g. button panel) to the GPIO port.
Power Connect the power cord to the AC power socket to the matrix unit.

Powering the device is recommended as the final step.

Ethernet Link to TPS inputs and TPS outputs
TPS lines do not transmit Ethernet signals, but they can be transmitted on the TPS input and output ports if there is a physical link between the motherboard and the input or the output board. This makes it possible to control a third- party device or supply Ethernet via TPS.
Connect a patch cable between

• Ethernet Link to TPS inputs and TPS inputs Ethernet labeled RJ45 connectors or
• Ethernet Link to TPS outputs and TPS outputs Ethernet labeled RJ45 connectors to create a link.
