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:
ñ
ñ
ñ
ñ
ñ
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
:
ñ
Is HDTV compatible
ñ
Includes a looping input and two outputs—per channel—all on BNC
connectors
ñ
ñ
Features independent termination and EQ. control per channel
Has a video bandwidth of 500MHz, ensuring transparent performance
even in the most critical applications
ñ
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:
ñ
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)
ñ
Avoid interference from neighboring electrical appliances and position
your VM-92 away from moisture, excessive sunlight and dust

required)
2. Connect CHAN. 9 as follows:
ñ
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
ñ
example, composite video recorder 9A), and the OUT 2 to acceptor 9B (for
example, composite video recorder 9B)
ñ
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
