2.1 Achieving the Best Performance
To achieve the best performance:
Use only good quality connection cables (we recommend Kramer high-
performance, high-resolution cables) to avoid interference, deterioration in
signal quality due to poor matching, and elevated noise levels (often
associated with low quality cables)
Do not secure the cables in tight bundles or roll the slack into tight coils
Avoid interference from neighboring electrical appliances that may adversely
influence signal quality
Position your Kramer VM-4HDxl away from moisture, excessive sunlight and
dust
This equipment is to be used only inside a building. It may only be
connected to other equipment that is installed inside a building.

Always switch off the power to each device before connecting it to your
VM-4HDxl. After connecting your VM-4HDxl, connect its power and
then switch on the power to each device.
To connect the VM-4HDxl as illustrated in the example in Figure 2, do the
following:
1. Connect an SD/HD/3G HD-SDI video source (for example, an SD/HD/3G
HD-SDI camera) to the INPUT BNC connector.
2. Connect up to four video OUT BNC connectors to the appropriate
SD/HD/3G HD-SDI video acceptors (for example, SD/HD/3G HD-SDI
displays).
You do not have to connect all outputs.
3. Connect the 5V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 2).
