These inverse equalizers are cable simulators and produce cable equivalent tilt. An inverse equalizer is plugged in the AUX socket of an amplifier. The inverse equalizer is normally used during amplifier balancing when an amplifier is short spaced, in order to achieve a flat input signal into the first amplifier stage. Each inverse equalizer has a dB value indicating the length of cable that would produce similar tilt (loss differential from 47 MHz to 862 MHz). The value in dB is printed on the top of each inverse equalizer. The inverse equalizer can be used at all frequencies from 5 MHz to 862 MHz with the loss values given in the table below.
