These safety instructions are to ensure the long life of your MTX unit and to prevent fire and shock hazard. Please read them carefully and follow all warnings.
1.1 General
Do not open the cover of the equipment since there are high-voltage components inside creating the
risk of electric shock.
Qualified Comm-Tec service personnel, or authorized representatives must perform all service. Service
preformed by unauthorized personnel without prior approval will void the warranty.
Changes or modifications not expressly approved by the manufacturer (responsible for compliance)
could void the user’s authority to operate the equipment.
1.2 Installation
For best results, place the unit on a flat, level surface in a dry area away from dust and moisture.
Handle the Matrix Switcher carefully. Dropping or jarring can damage internal components.
Do not place heavy objects on top of the equipment.
To prevent fire or shock, do not expose this unit to rain or excessive moisture. Do not place the
equipment in direct sunlight, near heaters or heat radiating appliances, or near any liquid. Exposure to direct sunlight, smoke, or steam can harm internal components.
To turn off the main power, be sure to remove the power cord from the power outlet. The power outlet
socket should be installed as near to the equipment as possible and should be easily accessible. Make sure the outlet is properly grounded for safety as per local regulations.
Do not pull the power cord or any cable that is attached to the equipment.
If the equipment is not used for an extended period, disconnect the power cord from the outlet to avoid
fire, shock, and loss of power.
1.3 Safety Guidelines for the Rack-Mounting of the Equipment.
Never restrict the airflow through the equipments’ fan or vents.
Normal operating ambient temperature is between 40-100 degrees F (5 – 40°C).
When installing equipment into a rack, distribute the units evenly. It is recommended to leave one space
on top and bottom of equipment.
Connect the unit to a properly rated power circuit (100V - 240V, 50/60Hz).
Reliable grounding of the Rack-Mounted Equipment should be maintained.
1.4 Cleaning
Unplug the equipment power cord before cleaning. Clean surfaces with a dry cloth. Never use strong
detergents or solvents, such as alcohol or thinner. Do not use a wet cloth or water to clean the unit.

2.4 Back Panel
Rear Panel of 8 x 8 BNC Stereo Audio-Cinch
Depending on the model of the matrix, the video signal I/O interface is made up of 4 or 8 channels on RCA terminals or 16 BNC female terminals. Audio signal I/O terminals are made up of 4, 8 or 16 RCA terminals for each channel (left & right). The channel numbers of the signal I/O terminals start from channel 1 to the maximum number of channels depending on the model. Audio left state terminals are white, audio right state terminals are red RCAs. Please refer to back panel figure for other types of interfaces
The AV matrix switchers have an internal power supply with IEC female connector for power cord. There is a 9pin SubD female connector for RS-232 port. An RJ-11 port (Auxiliary) is for future expansion.
