3 Overview
The Kramer VP-72 Multiformat 1:2 Distribution Amplifier is designed as a
companion unit to the ProScale™ series of Digital Scaler/Switchers. When
placed between two ProScale™ Digital Scaler/Switchers, the VP-72 allows
one ProScale™ to be used as a preview device and the other as the program

device, simultaneously. The VP-72 can be used as a 7 input 1:2 DA for all
distribution applications. In particular, the VP-72:
 Includes two 1:2 composite video distribution amplifiers on BNC
connectors, two 1:2 Y/C distribution amplifiers on 4p connectors, two 1:2
VGA distribution amplifiers on HD15 connectors, and one 1:2 YUV
distribution amplifier on BNC connectors
 Includes Gain

and EQ., control, as well as ID Bit control
 Has video bandwidth exceeding 400MHz, ensuring that it remains
transparent in almost any application
 Is housed in a 19-inch rack mountable enclosure requiring one vertical
rack space and is fed from any 100-240VAC, 50/60Hz mains supply
Achieving the best performance means:
 Connecting 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)
 Avoiding interference from neighboring electrical appliances that may
adversely influence signal quality and positioning your VP-72 unit in a
location free from moisture and away from excessive sunlight and dust

 Connect the s-Video source
2
to the Y/C A INPUT 4p connector
 Connect the Y/C A1 OUT 4p connector to the s-Video YC1 INPUT 4p
connector of the second VP-724xl unit
 Connect the Y/C A2 OUT 4p connector to the s-Video YC1 INPUT 4p
connector of the first VP-724xl unit
4. Connect the VGA sources and acceptors, as follows:
 Connect the VGA source (for example, a graphics card from a PC) to the
VGA A INPUT HD15 connector
 Connect the VGA A1 OUT HD15F connector to the VGA 1 HD15F
