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).
