Product overview

Developed to complement the ZoneVu Series 3 video matrix system the ZVP-

VDA321-4 is a high performance Video Distribution Amplier (VDA) and al-

though designed to match the superior specication of the Series 3 matrix it can

be used in any solution that requires the distribution of video signals without

any loss of image quality.

The module provides thirty two independent channels of four outputs per

bridged input via six BNC connectors per channel. All connections to the ZVP-

VDA321-4 are via the rear panel and it has been designed to t into a standard

19-inch Euro cubicle. The module itself is a very compact 5U high. Power to the

unit is supplied through an external PSU (E.g. one ZVS3-PSU-R per two VDA

modules), which is monitored by two power status LED’s on the VDA’s front

panel.

The ZVP-VDA-321-4 provides a multi-channel 1-in to 4-out video distribution

amplier with built in Automatic Gain Control (AGC) and is therefore a plug and

play solution requiring no engineer set up or conguration for ease of installa-

tion and minimum maintenance requirements.The AGC function operates on the

video sync pulse and will scale the entire video signal in order to restore that

level to 0.3Volt.

Each of the 32 video inputs has a bridging connection to allow the video input

to be daisy-chained. Where the unit is at the end of the chain, then the bridged

input can be used to terminate the video signal with a suitable 75R termination

plug.
