VIDEO AMPLIFIERS
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.
