American Dynamics ad1421 Data Sheet

FEATURES

The AD1421 Series Video Distribution Amplifier

distributes and amplifies the signal from one

video input to four video outputs. Independent

and isolated amplifiers for each individual

output means that shorts, opens or noises on

one output will not affect the remaining three

outputs. No manual adjustment required.

The AD1422 Series Video Line Amplifier

amplifies and equalizes the signal from a single

video input to a single remote video output. An

easy-to-use, continuously adjustable control

equalizes all amplifier characteristics,

simultaneously correcting for signal loss, high

frequency attenuation, differential delay and

other signal distortions typically associated with

long video cables. The unit restores picture

quality on video cables up to 1,500 m (one mile)

in length. Two units can be cascaded together

for distances up to 3,000 m (two miles).

On both units, a front panel LED indicates

presence or absence of video. When the video

amplifier detects video loss, it can automatically

trigger an alarm.
