2 Getting Started
We recommend that you:
Unpack the equipment carefully and save the original box and packaging
materials for possible future shipment
Review the contents of this user manual
Go to http://www.kramerelectronics.com/support/product_downloads.asp
to check for up-to-date user manuals, application programs, and to check if
firmware upgrades are available (where appropriate).
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-100YC 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.

VM-100YC - Overview
3 Overview
The VM-100YC is a high quality 1:10 s-Video Distribution Amplifier for s-Video (Y/C)
signals. It accepts one input, provides correct buffering and isolation, and distributes
the signal to 10 identical outputs using 4-pin connectors. The looping connector can
be used to connect to a local display or other Y/C acceptor, or to create larger
systems (for example, connecting three VM-100YC units to make a 1:30 s-Video
Distribution Amplifier).
In addition, the VM-100YC features:
Bandwidth (Y) - 275MHz (-3dB)
Level (gain) controls - Y and C (on the underside)
Selectable input signal termination
A compact desktop size. Two units can be rack mounted side-by-side in a
1U rack space with the optional RK-1 adapter

4 Connecting the VM-100YC
Always switch off the power to each device before connecting it to your
VM-100YC. After connecting your VM-100YC, connect its power and
then switch on the power to each device.
To connect the VM-100YC as illustrated in the example in Figure 2:
1. Connect the s-Video source (for example, an s-Video player) to the INPUT
4-pin connector.
2. Connect the OUT 4-pin connectors to up to 10 s-Video acceptors (for
example, s-Video recorders).
3. If required, connect the LOOP 4-pin connector, when looping units and
release the TERM switch on first unit (selecting Hi-Z). Push in the TERM
switch on the second unit (selecting 75).
4. Connect the 12V DC power adapter to the power socket and connect the
adapter to the mains electricity (not shown in Figure 2).
5. Switch on the VM-100YC.
The s-Video source distributes to the s-Video acceptors.
