Overview
The VEA-8707A Precision Video Equalizing Amplifier with Clamping precisely and easily
equalizes your choice of three popular coaxial cable types: Belden 8281, 1694, or 1505A. This
3-cable type selection ability is achieved to a level of accuracy never before obtained in a single
amplifier. All other amplifiers on the market are designed primarily for one type of cable and
usually achieve mediocre results with other cable types, or require complex and time-consuming
adjustment procedures.
During installation, the setting of a single adjustment is all that is needed to obtain unparalleled
equalization accuracy, thanks to very accurate factory-calibration. The need to use elaborate
frequency response measuring equipment in the field is eliminated.
Back porch clamping is provided to assist in the removal of hum or other signal disturbances.
Two clamping speeds are jumper selectable. A differential input gives excellent ground loop
rejection. The amplifier input may be AC or DC coupled.
Temperature drift effects are almost non-existent due to the use of the latest in analog ASIC’s
combined with meticulous product engineering.
The power to each VEA-8707A is individually fused to prevent failure of any one card from
affecting the rest of the cards in the frame.
