Abstract:
1. An acoustic drum set amplifier device specifically calibrated for each instrument within a drum set comprising: an electric power supply input; at least one electro-acoustical sound input channel that receives an electro-acoustical signal captured by a microphone, the electro-acoustical sound input channel comprises of an amplifier that increases the intensity of the signal received by the microphone to generate an electro-acoustic signal, said electro-acoustical sound input channel is connected to said electric power supply input; at least one selectively operable variable frequency filter that filters signals having frequencies ranging from about 40 Hz to about 300 Hz generated from the electro-acoustical sound input channel amplifier, to identify and control any signal having a frequency outside of the desired range, said selectively operable variable frequency filter is connected to said electro-acoustical sound input channel; at least one pre-calibrated dynamic compressor that compresses the electrical signal filtered through the selectively operable variable frequency filter within a predetermined compression range, said pre-calibrated dynamic compressor is connected to said selectively operable variable frequency filter; at least one variable frequency manipulator that manipulates frequencies of the electro-acoustical signal compressed by the pre-calibrated dynamic compressor ranging from about 41 Hz to about 16 Khz, the variable frequency manipulator further comprises of a selectively operable fixed frequency filter that filters electrical signals having frequencies less than 80 Hz, said variable frequency manipulator is connected to said pre-calibrated dynamic compressor; an electro-acoustical signal mixer, said electro-acoustic signal mixer is connected to said variable frequency manipulator, the electrical acoustical signal mixer receives the manipulated frequencies from each frequency manipulator and further mixes the manipulated signal; at least one output channel, said output channel is connected to said electro-acoustic signal mixer, each output channel receives the manipulated signal from the electro-acoustical signal mixer and then provides a mixed manipulated output signal; and an output channel volume control, said output channel volume control is connected to said output channel.
