Abstract

788,543. Reproducing music. GRIFFIN, A. A. Oct. 25, 1955 [Aug. 27, 1954], No. 24996/54. Class 40 (4). In a circuit arrangement for feeding a " woofer " and a " tweeter," a signal applied to condenser 19 produces two signals in antiphase in channels 22, 23. The channels include tetrode amplifiers 27, 32 feeding output transformers 36, 39 and the base frequencies are substantially removed from the treble channel 22 by a condenser 24 of small capacity.
