To achieve the best performance:
Connect only good quality connection cables, thus avoiding interference,
deterioration in signal quality due to poor matching, and elevated noise levels
(often associated with low quality cables)
Avoid interference from neighboring electrical appliances that may
adversely influence signal quality and position your Kramer VM-2C away
from moisture, excessive sunlight and dust

5 Connecting the VM-2C
To connect a VM-2C unit, as the example in Figure 4 illustrates, do the
following1:
1. Connect a component video source (for example, a DVD player) to the Y,
PB/CB, and PR/CR INPUT RCA connectors.
2. Connect the two sets of OUTPUT (Y, PB/CB, and PR/CR) RCA
connectors2 to up to two component video acceptors (for example, to two
displays).
3. Connect the 12V DC power adapter (wall transformer) to the 12V DC
socket and connect the transformer to the mains electricity (not illustrated
in Figure 4).
