    N T R O D U C T I O N The OEQ is an octave equalizer used to help compensate for acoustical inaccuracies common in the automobile environment. The OEQ is a stereo equalizer with ten bands of frequency adjust- ment spaced at octave intervals.

  • Page 5: Technical Design Features

    ECHNICAL ESIGN EATURES High-Q Filters Hi-Q filters are utilized for adjusting narrow frequency bands in an equalizer. Filter “Q” or Quality Factor is a measure of the “narrow- ness” of the filter response. Using Low-Q (wide) filters in an equalizer allows adjustments made on one control to strongly effect neighbor- ing frequencies during boost or cut.

    OUNTING OCATION The mounting location for the OEQ should allow easy access to the controls for making necessary adjustments. The OEQ will most likely be adjusted only at the time of installation and will not need further adjustment unless changes to the audio system are performed. To ensure optimum performance, care should be taken when mounting the equal- izer in the following locations: Engine Compartment...

    PERATION Boost/Cut Control The Boost/Cut controls are used to increase or reduce emphasis in a specific octave of music. Each control provides up to 12dB of boost or cut to the selected frequency. The following graph shows the effect of each control at the full boost (+12dB) and full cut (–12dB) positions.
  • Page 17 Frequency Warp Control The Frequency Warp controls are used to fine adjust the center frequency of the Boost/Cut controls. Each Warp control allows for a range of 1/2 octave above and below the center frequency. The following graph illustrates the operating range of the 1kHz Warp control at its minus (–), center (•), and plus (+) positions.
  • Page 18 Engage/Bypass Switch The Engage/Bypass Switch is useful in system tuning when comparing the differences between an equalized and non-equalized system. With the switch in the IN position, all EQ functions are engaged and can be heard. With the switch in the OUT position, all EQ functions except the input gains and output attenuators are bypassed from the signal path.
