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).
