Michael Faraday http://www.rigb.org/our-history/michael-faraday Electro-magnetism Faraday’s Law of Induction: Basically, any change in the magnetic field of a coil of wire will cause a voltage to be induced in a wire. Conversely, any change in the voltage on a coil of wire will cause the magnetic field to change. This is called electromagnetism, and the field created is called an electro-magnetic field. Capacitance When two conductors are given an opposite charge, an electric or more specifically a capacitive field is generated around them. When the relationship between the two conductors (for example the distance between them) changes it causes measurable effects on the charges. http://hyperphysics.phy-astr.gsu.edu/hbase/electric/imgele/cap.png Capacitance When two conductors are given an opposite charge, a electric or more specifically a capacitive field is generated around them.

This unit is the result of our customers asking us to make a vocal oriented combination from some favorite Manley designs. We combined the Manley Mic Preampli- fier, Electro-Optical Limiter, and Mid Pultec and then went further. Uniquely, we put a compressor before a minimalist mic preamplifier. This can substantially reduce distortion while having no more sonic imprint on the signal than the mic pre by itself because the compressor is just a passive light dependent clamping resistor. For those who want the shortest path to tape, but use compressors, this has to be the ideal solution. We added attack and release controls to the compressor with some “very special” settings such as one that simulates a LA-2A, another “tuned” for drums and a setting that works like a great engineer “riding” a fader. Then we extended the PULTEC MEQ down to 20 Hz and up to 20 kHz so its not just a mid EQ anymore.

  • Maximizing Efficiency in Active Loudspeaker Systems
    Maximizing Efficiency in Active Loudspeaker Systems Wolfgang Klippel, KLIPPEL GmbH, Dresden, Germany Increasing the efficiency of the electro-acoustical conversion is the key to modern audio devices generating the required sound output with minimum size, weight, cost and energy. There is unused potential for increasing the efficiency of the electro-dynamical transducer by using a nonlinear motor topology, a soft suspension and cultivating the modal resonances in the mechanical and acoustical system. However, transducers optimized for maximum efficiency are more prone to nonlinear and unstable behavior. Nonlinear adaptive control can compensate for the undesired signal distortion, protect the transducer against overload, stabilize the voice coil position and cope with time varying properties of the suspension. The paper discusses the design of modern active systems that combine the new opportunities provided by software algorithms with the optimization of the hardware components in the transducer and power amplifier. reducing power consumption in portable 1 Introduction applications with limited battery capacity. The user of loudspeakers, headphone and other For this discussion, the paper provides new audio devices expects that the audio signal can be definitions of the efficiency to consider the influence reproduced at sufficient amplitude and quality but of the spectral properties of the complex audio prefers products which are smaller, lighter, less cost signals (e.g. music). The paper explains the intensive and provide a longer stand-alone operation difference between efficiency and voltage in personal applications. sensitivity, which is a second important Creating such an audio product requires a characteristic of the transducer required to match the combination of hardware and software components transducer with the power amplifier.
