One jack is for the input signal; the other is a loop through output of the source signal.The input stage is bridging. If 75 ? termination of the input signal is required, the termination is plugged onto the LOOP OUT jack.Gain is user adjustable from the front panel. The GAIN potentiometer allows adjustment from -1 dB to +7 dB.
