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
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 and position
your VM-100YC away from moisture, excessive sunlight and dust
Caution – No operator-serviceable parts inside unit.
Warning – Use only the Kramer Electronics input power
wall adapter that is provided with this unit
1
.
Warning – Disconnect power and unplug unit from wall
before installing or removing device or servicing unit.

5 Connecting the VM-100YC
To connect the VM-100YC 1:10 s-Video Distribution Amplifier,as the
example in Figure 2 illustrates, do the following
1
:
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.
