Abstract

323,016. Electramonic Co., Ltd., Tyrrell, S. J., Tyrrell, L. N., and Sayers, D. W. Sept. 18, 1928. Systems for transmitting music. - The invention relates to systems in which an amplified reproduction is obtained selectivelv from several sources, such as gramophone records, and comprises in 'its simplest form the arrangement shown in Fig. 1, in which by moving the contact arm 5 over the high resistances 3, 4 from the central point, either of the sources 1, 2 may be introduced with increasing effect. In a modification, the sources are coupled to the resistances 3, 4 through transformers. Fig. 5 shows an arrangement in' which a third source 19 may be introduced by a contact arm 21 moving over a resistance 20 either independently or superposed on either of the sources 1, 2, while Fig. 7 shows a further development in which any of the four sources may be switched in independently, or either of the sources 1, 2 may be combined with either of the sources 17, 22.
