To simplify coupling of a video recording transducer to a recording network, and to improve the fidelity of the signals as actually recorded with respect to the signals applied to the recording network, an amplifier, preferably a current amplifier including emitter-coupled transistors, is connected between a current-supplied compensating network and the transducer, the connection being through a short cable, preferably a coaxial cable which has a length substantially less than the wave length of the signals to be recorded, so that the overall response of the compensating network-amplifier-cable-transducer will be essentially linear with respect to the signals to be recorded.
