  • Method and system for equalization of a replacement load
    Patent number: 7684480
    Abstract: A system (10) and method (50) of equalizing an audio signal from an existing radio or head unit (30) using an interface unit (10) between the radio or head unit and a replacement load (34) can include the steps analyzing (64) an existing equalization to provide a measure of an existing frequency response, generating (66) a substantially inverted frequency response to the existing frequency response, and applying (74) the inverted frequency response to the replacement load to provide a desired response. Such as system can include an interface unit (12) having an automatic input level control unit (14), an analog to digital converter or digitizer (16), a DSP (18) providing an output to a DAC (20), a level booster unit (22) and a processor such as a microcontroller unit (24).
    Type: Grant
    Filed: November 30, 2006
    Date of Patent: March 23, 2010
    Assignee: JL Audio, Inc.
    Inventors: Campbell Kelly, Manville Smith, Bruce MacMillan, Felix Matro, Carl Lindquist

  • Method and system for equalization of a replacement load
    Patent number: 7167515
    Abstract: A system (10) and method (50) of equalizing an audio signal from a factory installed radio (30) using an interface unit (10) between the factory installed radio and a replacement load (34) can include the steps of measuring (52) an existing equalization for the factory installed radio in the interface unit, analyzing (64) the existing equalization to provide a measure of an existing frequency response suited for an old load, generating (66) a substantially inverted frequency response to the existing frequency response, and applying (74) the inverted frequency response to the replacement load to provide a desired response. Such as system can include an interface unit (12) having an automatic input level control unit (14), an analog to digital converter or digitizer (16), a DSP (18) providing an output to a DAC (20), a level booster unit (22) and a processor such as a microcontroller unit (24).
