SAFETY OPERATION GUIDE
In order to guarantee the reliable operation of the equipment and safety of the
user, please abide by the following procedures in installation, use and
maintenance:
1. The system must be earthed properly. Please do not use two blade plugs
and ensure the alternating power supply ranges from 100v to 240v and from
50Hz to 60Hz.
2. Do not install the switcher in an environment where it will be exposed to hot
or cold temperatures.
3. This unit will generate heat during operation, please ensure that you allow
adequate ventilation to ensure reliable operation.
4. Please disconnect the unit from mains power if it will be left unused for a
long time.
5. Please DO NOT try to open the casing of the equipment, DO NOT attempt to
repair the unit. Opening the unit will void the warranty. There are high
voltage components in the unitand attempting to repair the unit could result
in serious injury.

1. Introduction
AVG-DMMS88A is a high-performance 8x8 video and audio modular matrix switcher.
It supports different video signals with crosspoint switching. Every video or audio
signal is transmitted and switched independently to decrease signal attenuation.
AVG-DMMS88A supports various changeable cards including HMDI, DVI, VGA, SDI
and HDBaseT etc, and all the cards support hot plug & play. Users can choose to
insert different signal cards for different configurations and applications.
AVG-DMMS88A has a power fail memory function and audio can break away from
or follow the video switched. It has an RS232 port for serial control and an optional
IP port for TCP/IP control, allowing it to be easily controlled by third-party devices.
With its flexible design, the AVG-DMMS88A can be used for different projects
allowing the design to scale to suit the solution. The AVG-DMMS88A is designed to
suit multimedia conferencing rooms, control rooms, television broadcast control
rooms, shopping centers etc. It will handle all the audiovisual management, including
the switching, signal path, scaling etc.
