Video Equalizing Amplifier with Clipping and Clamping
For use where clamping and white clipping is required in addition
to precision cable equalization.
The basic amplifier equalizes Belden 8281 cable but several versions for other cable types
are available at no extra charge.
The back porch clamping speed is adjustable. Fast mode offers excellent hum rejection
(>45 dB) while Normal mode provides good hum rejection (>33 dB) with superior immunity
to noise.
An adjustable white clipper is included to limit peak white signal excursions and protect the
following equipment from overload. Two clipping modes are available. Flat mode causes all
frequencies to be clipped equally. Luminance Only mode avoids clipping chroma. The clipper
is of an advanced design which maintains excellent signal linearity to within 1.5% of the
clipping point.
A differential input provides excellent rejection of input ground loop interference.
Temperature drift effects are almost non-existent due to the use of the latest in analog
ASICs combined with meticulous product engineering.
