A dynamic threshold voltage system for neutralizing the unwanted electrical signals caused by intertrack crosstalk as generated in multi-track electromagnetic transducers. The system is responsive to the amplitudes of intelligence bearing electrical signals to generate a direct current voltage threshold level which is a predetermined ratio of the intelligence bearing signal. This threshold level is applied to all of the data channels for the multi-track electromagnetic transducer to effectively neutralize any unwanted crosstalk originated signal appearing on any channel.
