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.
