1. Product Introduction
The Alfatron ALF-MMX3232 is a high-performance video and audio modular matrix
switcher supporting a maximum of 32 input sources and 32 output displays
synchronously. It supports different video signals with cross switching. Every video or
audio signal is transmitted and switched independently to decrease signal attenuation.
The ALF-MMX3232 matrix supports various changeable cards including HMDI, VGA,
and HDBaseT. Users can choose to insert different signal cards for different
applications.
The matrix has a power failure memory function and audio can break away from or
follow the video switching. The matrix has an RS232 port for serial control and an
optional IP port for TCP/IP control, which can be easily controlled via third-party
devices.
With its flexible design, the ALF-MMX3232 matrix can be used for an array of different
projects and tend to be an all-in-one solution. It is the combination solution for
multimedia conference rooms, control rooms, broadcasting rooms, shopping center,
etc. It will handle all the audiovisual management, including the switching, driving,
scaling, etc.
1.1. Features
Modular chassis with configurable I/O slots, ranging from 4x4 to 32x32.
Various I/O cards, includes HDMI, HDBaseT, and VGA cards (Compatible with
YUV, YC & CVBC.) to configure any matrix.
Truly cross-point switching, any input to any output, regardless signal format.
Supports HDMI1.4 and 1080P 3D.
Integrated HDBaseT technology.
Controllable via front panel buttons, RS232, and optional TCP/IP, also compatible
with third party control.

3.1. Usage Precaution
Ensure all components and accessories are included before installation.
System should be installed in a clean environment with adequate temperature and
humidity.
All of the power switches, plugs, sockets, and power cords should be insulated and
safe.
All devices should be connected before powering on.

4. Button Control
The matrix can be controlled via the front panel buttons. To switch AV signal, please
operate the buttons using the following order:
Order: “Input Channel” + “AV” +“Output Channel” + “Enter”
Note:
Input Channel: Fill with the number of the input channel to be controlled.
Output Channel: Fill with the number of output channels to be controlled. Press “All”
to select all the outputs.
Use “,” button to separate multiple I/O channels, and press “ENTER” button to
confirm the operation.
The input/output channels on the rear panel are counted from left to right, top to
bottom.
The input delay time between two numbers of every input & output channel must be
less than 5 seconds; if not, the operation will be cancelled.
Example: To transfer input 1 to output 11, press input “1”, output “1” “1” and
“Enter”.
To transfer signals from input 1 to all output channels, press buttons in
this order: “1”, “All”.
