1. IN COMBINATION FOR USE IN APPARATUS FOR REPRODUCING INFORMATION FROM A STORAGE MEDIUM AS REPRESENTED BY SIGNALS HAVING A WIDE RANGE OF FREQUENCIES AND FOR INTRODUCING SUCH SIGNALS TO A STAGE HAVING A FIRST PARTICULAR IMPEDANCE, A HEAD CONSTRUCTED TO PROVIDE A TRANSDUCING ACTION BETWEEN SIGNALS IN THE HEAD AND INFORMATION IN THE STORAGE MEDIUM AND PROVIDED WITH A SECOND PARTICULAR IMPEDANCE DIFFERENT FROM THE FIRST PARTICULAR IMPEDANCE, A FIRST TRANSFORMER HAVING A PRIMARY WINDING AND A SECONDARY WINDING AND PROVIDED WITH CHARACTERISTICS TO RESPOND TO SIGNALS AT THE HIGH FREQUENCIES IN THE RANGE AND TO PROVIDE AN IMPEDANCE MATCH BETWEEN THE FIRST AND SECOND PARTICULAR IMPEDANCES AT THE HIGH FREQUENCIES, A SECOND TRANSFORMER HAVING A PRIMARY WINDING AND A SECONDARY WINDING AND PROVIDED WITH CHARACTERISTICS TO RESPOND TO SIGNALS AT THE LOW FREQUENCIES IN THE RANGE AND TO PROVIDE AN IMPEDANCE MATCH BETWEEN THE FIRST AND SECOND PARTICULAR IMPEDANCES AT THE LOW FREQUENCIES, MEANS CONNECTED IN A CIRCUIT WITH THE HEAD AND THE PRIMARY WINDINGS OF THE FIRST AND SECOND TRANSFORMERS TO PROVIDE FOR THE PASSAGE OF THE SIGNALS AT THE HIGH FREQUENCIES THROUGH THE FIRST TRANSFORMER AND FOR THE PASSAGE OF THE SIGNALS AT THE LOW FREQUENCIES THROUGH THE SECOND TRANSFORMER AND TO PROVIDE FOR A BY-PASS OF THE SIGNALS AT THE HIGH FREQUENCIES FROM THE PRIMARY WINDING OF THE SECOND TRANSFORMER TO INHIBIT THE PASSAGE OF THE SIGNALS AT THE HIGH FREQUENCIES THROUGH THE SECOND TRANSFORMER, AND MEANS CONNECTED IN A CIRCUIT WITH THE SECONDARY WINDINGS OF THE FIRST AND SECOND TRANSFORMERS TO PROVIDE AN INTEGRATION OF THE SIGNALS AT LOW FREQUENCIES FOR A BOOST OF SUCH SIGNALS AND TO PROVIDE A BY-PASS OF THE SIGNALS AT THE HIGH FREQUENCIES FROM THE SECONDARY WINDING OF THE SECOND TRANSFORMER TO INHIBIT THE PASSAGE OF THE SIGNALS AT THE HIGH FREQUENCIES THROUGH THE SECONDARY WINDING OF THE SECOND TRANSFORMER.
