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.
