Abstract
439,307. Distributing music. STANDARD RADIO RELAY SERVICES, Ltd., Bush House, Aldwych, and ADORJAN, P., 13, Gledhow Gardens, Old Brompton Road, both in London. July 10, 1934, No. 20204. Drawings to Specification. [Class 40 (iv)] [See also Group XL] The input to a push-pull audio-frequency amplifier is fed through two series resistances, one in each lead, and two series condensers. Between the resistances and the condensers, a variable resistance is shunted across the leads, the adjustment of which enables a series of amplifiers, when fed from a single source, to share the load equally or in the most suitable proportion. The series resistances impose a lower limit on the input impedance of any of the amplifiers.
