lots for up to 17 matrix cards (15 blanks
cover 15 of the slots)
MTX3-34-M has 17 slots for insertion of matrix cards.
MTX3-34-M uses hot plugging, so cards can be inserted while the device is
operating, and the card’s ports are automatically categorized as input or output.
Use the system menus to change input/output designations and to create
flexible connections between the ports on different cards.
MTX3-34-M identifies ports by the ID numbers it allocates to each card slot:
See MTX3-34-M ID numbers below to understand how they are defined.
MTX3-34-M ID numbers
The matrix cards that are installed to the MTX3-34-M, can have input and/or output ports. Each inserted card is allocated with
2 port ID numbers. Port input/output directions are defined per ID number. The port ID numbers are written on the chassis,
next to each card-insertion slot. Ports on the upper side of the card use one ID number and ports on the lower side of the card
use the next ID number.
Matrix cards can have up to 4 input/output ports, 2 for each ID number. Ports with the same ID have the same input/output
direction.

Step 3: Install the MTX3-34-M
To rack mount the machine, attach both rack ears (by
removing the screws from each side of the machine
and replacing those screws through the rack ears) or
place the machine on a table.
• Ensure that the environment (e.g., maximum ambient
temperature & air flow) is compatible for the device.
• Avoid uneven mechanical loading.
• Make appropriate consideration of equipment nameplate
ratings to avoid overloading the circuits.
• Maintain reliable earthing of rack-mounted equipment.
Step 4: Connect the inputs and outputs
Insert the input and output cards into the card slots and then connect the inputs and the outputs.
You can insert cards into slots while the device is powered.
For optimum range and performance use the recommended Kramer cables
available at www.kramerav.com/product/MTX3-34-M.
Using third-party cables may cause damage!
Step 5: Connect the power
Connect the power cord to MTX3-34-M and plug it into the mains electricity.
