Forward Linear Equalizers
Forward linear equalizers produce linear tilt. A linear equalizer should be used in the plug-in input
or interstage equalizer location if a node output tilt does not have the desired station output tilt. The
EQ value is the amount of tilt from lowest to highest frequency (52
– 1002 MHz).
