Abstract
850,259. Stereophonic pick-ups. ERIE RESISTOR CORPORATION. April 13, 1959 [May 26, 1958], No. 12407/59. Class 40 (4). A stereophonic pickup is arranged such that the signals generated in each channel by vertical displacements in a 45-45 cut recording are out of phase so that by shunting the channels with a low pass filter turntable rumble may be attenuated. To obtain the out-of-phase components a rod-shaped transducer may be polarised as shown in Fig. 4. Separate crystal bimorphs set in planes perpendicular to one another and at 45 degrees to the plane of a record also provide suitable out-of-phase components of rumble which may be shunted by a filter.
