How An Equalizer Is Used

The Planet Audio PEQ10 parametric equalizer is a high-fidelity signal processor/preamplifier that allows you to control the relative levels within the audible frequency spectrum of a stereophonic system. It is intended for use in a car audio system which includes amplifiers in a signal path after the equalizer, and provides front, rear, and subwoofer low level outputs via RCA connectors.


  • EQ center frequencies: 75Hz – 200Hz – 2kHz – 20kHz
  • Equalization range: +/- 18 dB (boost/cut)
  • Frequency response: 20Hz – 20kHz
  • Subwoofer crossover frequency: Variable 45 – 180Hz
  • Signal to noise ratio: 105 dB
  • THD: 0.05%
  • Subwoofer channel THD: 0.05%
  • Channel separation: 60 dB
  • Low Level Input Voltage: 0.5 V
  • Defeat/Equalizer: 0 dB/ +/-1 dB
  • Power supply: 10-16V negative ground
  • Output voltage: 7V RMS

  5. Subwoofer Gain: This control permits you to increase or decrease the output level of the subwoofer channels.
  6. Boost/Cut Controls: Each of these controls represent a range of frequencies surrounding a center frequency to cover the audio spectrum from subwoofer frequencies to treble frequencies. Adjust these controls to suit your taste and listening environment. Each center frequency can be adjusted +/- 12 dB.

    Parametric equalizer Bought a few peq15 for my customers they are a copy of the soundstream mpx4. The thing people must know is this a parametric witch means you can sweep across the secified range eg: Band 4= 4k-20khz you can boost or cut any frequency 4,001hz to 19,999hz. EG: If your car has resonance problems at 6000 hz with a flat tip screwdriver you can tune to this frequency and fix the issues by a boost or cut. If known how to use correctly it can be the most valuable component in youre system. It made my…
