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.
