Abstract: An instrument interconnect system that interfaces an instrument, such as a guitar or a bass, to an audio-receiving device, such as an amplifier, effect box, or a mixer. The instrument interconnect system provides enhanced clarity and sonic detail. The instrument interconnect system may allow a musician to select a voltage-buffered output signal, an unbuffered output signal, or may allow a musician to mix a voltage-buffered output signal and an unbuffered output signal. The instrument interconnect system may further allow the musician to selectively activate or deactivate gain-adjustment circuits and equalization circuits.

Abstract: A method for processing the audio signal in a loudspeaker system prior to delivery to the loudspeaker and the apparatus for such processing is disclosed. Uniform acoustic output with respect to frequency at frequencies below the resonant frequency of the loudspeaker system is achieved by changing the strength of the signal at a constant rate in inverse proportion to audio signal frequencies from a frequency below the resonant frequency to a frequency at least one octave above the resonant frequency. A method and apparatus for limiting the audio signal to prevent distortion is also disclosed.

Abstract: A process for transducing acoustical signals, including music, speech, noise, etc. which embodies a method which eliminates the usual discrimination between the frequency spectra of the direct and random incidence acoustical components of the sound being transduced and allows the frequency range of interest to be controlled by adjusting the spacing between the diaphragm or major entry port of an acoustical to electrical transducer and a boundary. The invention requires that the diaphragm or major entry port of the transducer be oriented substantially parallel with and proximate to a boundary.
