<p>An audio step-up circuit for driving an electrostatic loudspeaker of full-range-element configuration from a low voltage, low impedance, audio signal source utilizes two specially designed audio transformers in parallel-bilateral interconnection including R-C networks, one transformer being designed for optimum spectral response in the region of 30 Hz to about 5 kHz, and the other transformer being designed with cooperative added input impedance means for optimum spectral response in the region from a few hundred Hz to 20 kHz in such manner as to achieve an equalized-pass characteristic complementary to the loudspeaker therethrough in the audio range, while at the same time affording resonant conservation of energy at high frequencies.</p> |
