Equalizing Reference Guide
Introduction
Equalizing Reference Guide – Equalizers are powerful tools that allow you to shape the sound of your audio system. They work by boosting or cutting specific frequency ranges within the audio signal, allowing you to adjust the tonal balance of your music. This guide will help you understand the different frequency ranges and how to use them to improve your audio experience.

Understanding Frequencies
Low Frequencies (20Hz – 250Hz)
This range is often referred to as the bass. It includes the lowest frequencies that most people can hear and is where you’ll find the deep, booming sounds like the kick drum or bass guitar in a song. Boosting these frequencies can give your music a more powerful, full-bodied sound, but too much can make it sound muddy or boomy.
Mid-Low Frequencies (250Hz – 500Hz)
This range is often referred to as the low-mids or upper bass. It’s where you’ll find the lower notes of most instruments and the ‘body’ of many sounds. Boosting these frequencies can add warmth to your music, but too much can make it sound boxy or muffled.
Mid Frequencies (500Hz – 2kHz)
This range is often referred to as the midrange. It’s where our ears are most sensitive and where you’ll find the fundamental frequencies of most instruments and vocals. Boosting these frequencies can make your music sound more present and forward, but too much can make it sound harsh or nasal.
High-Mid Frequencies (2kHz – 6kHz)
This range is often referred to as the presence range. It’s where you’ll find the higher harmonics of most instruments and vocals, as well as many percussive sounds. Boosting these frequencies can add clarity and detail to your music, but too much can make it sound harsh or brittle.
High Frequencies (6kHz – 20kHz)
This range is often referred to as the treble. It’s where you’ll find the highest frequencies that most people can hear, including the ‘air’ and ‘sparkle’ in a recording. Boosting these frequencies can make your music sound more open and airy, but too much can make it sound thin or hissy.
Equalizing Different Instruments and Vocals
Drums
- Kick Drum: Boost around 60Hz to add more thump. Cut around 400Hz to reduce boxiness. Boost around 3kHz to add more click.
- Snare: Boost around 200Hz for more body. Cut around 1kHz to reduce harshness. Boost around 6kHz for more snap.
Bass Guitar
- Boost around 60Hz to add more bottom-end. Cut around 500Hz to reduce muddiness. Boost around 2.5kHz to add more growl.
Acoustic Guitar
- Boost around 100Hz to add more body. Cut around 1kHz to reduce boxiness. Boost around 10kHz to add more air.
Piano
- Boost around 60Hz to add more weight. Cut around 1kHz to reduce muddiness. Boost around 5kHz to add more presence.
Vocals
- Boost around 120Hz to add more body. Cut around 500Hz to reduce muddiness. Boost around 5kHz to add more presence. Boost around 10kHz to add more air.
Remember, these are just starting points. Every mix is unique, so use your ears and adjust the EQ to taste.
Conclusion
Understanding equalizer frequencies is key to getting the best sound out of your audio system. By knowing what each frequency range does, you can make more informed decisions when adjusting your EQ settings. Remember, the goal is to achieve a balanced sound that suits your personal taste and the acoustics of your listening environment. Happy listening and mixing!
