VEA-6840 Video Equalizing

Amplifier Module

Overview

The VEA-6840 is a reliable, high-performance and full-featured

equalizing video distribution amplifier. This DA provides a

jumper-selectable input coupling mode (DC or AC coupling), and is

capable of hard and soft clamping to the composite NTSC and PAL

video signal.

The VEA-6840 is equipped with continuously variable equalization for

coaxial cable, features a differential input and eight outputs, and includes

both gain adjustment (with a range of –3.0 dB to +3.0 dB) and high-

frequency response adjustment on the front edge of the board.

An optional Removable Gain and Equalization (EQ) setting submodule

can be used with the VEA-6840. This submodule can be quickly and

easily moved from one DA to another without gain and equalization

readjustment.

Specifications and designs are subject to change without notice.
