    A central feature of the new design of a stereo amplifier is an output transformer with original features that makes possible reduced cost and improved performance at the same time. This paper discusses a varied possibility of design objectives for a stereo system, and explains the way in which the new output transformer functions. By variation in its method of use, or in choice of parameters, a w... View full abstract»

    Some two-channel stereo systems have employed a third full-range speaker system in the center, reproducing an equal in-phase mixture of the signals in the two channels. Advantages of this arrangement over the usual two-speaker array are better reproduction of the location and size of central sound sources. A disadvantage is the sizeable reduction in the apparent spread, or distance between flankin... View full abstract»

    The response of a loudspeaker to sudden starts and stops of its input signal is analyzed both theoretically and experimentally. Transient distortion occurs when the acoustic output level does not change as suddenly as the input signal. Waveforms of loudspeaker response to various input signals are shown, and a method for plotting a continuous transient response curve is described. The curves indic... View full abstract»

    This paper describes a low-noise two-transistor pre-amplifier which has been developed for use with microphones. For a source resistance of 1000 Ω, a noise figure of 1.3 db has been achieved. A corresponding middle-frequency gain of 40 db, bandwidth of 30 kc and output impedance of 175 Ω resulted. View full abstract»

    Investigation, both theoretically and experimentally, was made into the mode of operation of cathode followers and feedback amplifiers with high-capacitance loads. The capacitance loaded cathode follower compares unfavorably with the resistance loaded cathode follower, particularly regarding operation with fluctuating input signals. Input overdrive of a capacitance loaded cathode follower causes p... View full abstract»
