Adjust an Audio Equalizer


Most people don't have a real-time analyzer so the best way to adjust a stereo audio equalizer is by ear, using personal listening preferences as a guide. Everyone has different opinions about the best sound, so use the following steps to adjust an equalizer to your tastes.
Difficulty: Easy
Time Required: One Hour

Here's How:

  1. Ensure Correct Speaker Placement: Before using an equalizer, make sure the speakers are placed correctly. Follow these guidelines for correct speaker placement. By placing speakers correctly you will be starting from the best sound possible in your listening room.

  2. Set Equalizer Controls to Neutral: Start with the equalizer controls set at the neutral or ‘0’ position.

  3. Adjust Equalizer Controls: Based on your opinion about which frequencies need to be adjusted, or based on your listening preferences, make small adjustments (increase or decrease) in level one frequency control at a time. Make several small adjustments in level rather than large changes.

    It is always best to cut or reduce than to increase a frequency. Increasing a frequency can add small amounts of distortion. If you want to increase high frequencies, try cutting the midrange instead. Or if you want more midrange, try cutting the level of high frequencies.
  4. Evaluate the Sound Quality: After making the first adjustment, listen to the system with a familiar disc or source and evaluate the quality of the sound.

  5. Make Further Adjustments: Re-adjust the controls to make additional changes, or adjust another frequency control and repeat step 3 until you have achieved the sound quality you want.
