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-2C 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.

4 Connecting the VM-2C
Always switch off the power to each device before connecting it to your
VM-2C. After connecting your VM-2C, connect its power and then
switch on the power to each device.
To connect the VM-2C as illustrated in the example in Figure 2:
1. Connect a component video source (for example, a DVD player) to the Y,
PB/CB,and PR/CRINPUT RCA connectors.
2. Connect the OUTPUT RCA connectors (Y, PB/CB,andPR/CR)to up to two
component video acceptors (for example, a display and a projector).
3. Connect the 12V DC power supply to the 12V DC socket and then connect
the power supply to the mains electricity (not shown in Figure 2).
