KRAMER: SIMPLE CREATIVE TECHNOLOGY
Overview
3 Overview
The VM-92 is a high performance universal style video distributor. It can be
configured in several different ways, including as a:
9 x 1:2 composite video distributor with looping inputs
4 x 1:2 s-Video (Y/C) distributor with looping inputs
3 x 1:2 component (YUV) distributor with looping inputs
3 x 1:2 RGB distributor with looping inputs
2 x 1:2 RGBS distributor with looping inputs
Using the loop connectors and termination switches you can interconnect
several channels to form various combinations, for example, a 1:18 composite
video distributor or a 1:9 s-Video (Y/C) distributor.
In particular, the VM-92
:
Is HDTV compatible
Includes a looping input and two outputs—per channel—all on BNC
connectors
Features independent termination and EQ. control per channel
Has a video bandwidth of 500MHz, ensuring transparent performance
even in the most critical applications
Is housed in a 19" 1U rack-mountable enclosure and is fed from a 90-264
VAC universal switching power supply
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-92 away from moisture, excessive sunlight and dust

7 Connecting the VM-92 9x 1:2 Video Distributor
This section describes how to connect the VM-92 as a 9 x 1:2 Composite
Video distributor1.
To connect the VM-92, as the example in Figure 9 shows2, do the following3:
1. Connect CHAN. 1 as follows:
Connect a composite video source (for example, a composite video player
1) to the CHAN. 1 IN BNC connector
Connect the CHAN. 1 OUT BNC connectors4 OUT 1 to acceptor 1A (for
example, composite video recorder 1A), and the OUT 2 to acceptor 1B (for
example, composite video recorder 1B)
Connect a local display to the CHAN. 1 LOOP BNC connector (if
required)
2. Connect CHAN. 9 as follows:
Connect a composite video source (for example, a composite video player
9) to the CHAN. 9 IN BNC connector
Connect the CHAN. 9 OUT BNC connectors4 OUT 1 to acceptor 9A (for
example, composite video recorder 9A), and the OUT 2 to acceptor 9B (for
example, composite video recorder 9B)
Connect a local display to the CHAN. 9 LOOP BNC connector (if
required)
3. Connect the power cord to the mains electricity.
1 Also see the configuration illustrated in Figure 3
2 Only channels 1 and 9 are illustrated in Figure 9, but you can connect each channel in a similar way
3 Switch OFF the power on each device before connecting it to your VM-92. After con necting your VM-92, switch on its
power and then switch on the power on each device
4 As required. Not all outputs need to be connected
