ABSTRACT Circuitry for causing the two wires of a seismic signal channel to appear balanced to hiline signal induced from surrounding power lines and equipment. In this manner, the undesired differential mode hiline signal is eliminated from the channel and the common mode hiline signal on the lines may be eliminated by the input amplifier of seismic signal processing equipment. The lines are balanced by a respective in-phase and quadrature phase components of a correcting signal that is a scaled version of the common mode hiline signal on the lines seismic channel. The scaling is a function of the correlation between the hiline common mode signal and the hiline differential mode signal. The system operates so that the correcting signal causes the differential mode signal and the correlating signal to go to zero.
