ReQ·131 Instruction Manual
v1.2
Appendix 1:
Instrument Frequency ranges
To understand EQ and its intricacies you need hands-on experience, but through practice and use of
the ReQ·131 you will start to become accustomed to certain ‘ranges’ of the frequency spectrum.
Also, every sound that you use may sound different to someone else, even if you use the same sound –
different variables come into play (amplitude, pitch, envelope, bit rate,.. etc.), so you need to keep in
mind that the below listed frequency settings can be used with ‘a pinch of salt’; EQing is like seasoning
of your sound, it adds flavour (and can also take it away too).
The Kick Drum
Any apparent muddiness can be rolled off around 300Hz. Try a small boost around 5-7kHz to add some
high end.
50-100Hz ~ Adds bottom to the sound
100-250Hz ~ Adds roundness
250-800Hz ~ Muddiness Area
5-8kHz ~ Adds high end presence
8-12kHz ~ Adds Hiss
The Snare
Try a small boost around 60-120Hz if the sound is a little too wimpy. Try boosting around
6kHz for that 'snappy' sound.
100-250Hz ~ Fills out the sound
6-8kHz ~ Adds presence
The Hi hats, The Cymbals, The Rides & The Other High-end Percussive sounds
Any apparent muddiness can be rolled off around 300Hz. To add some brightness try a small boost
around 3kHz.
250-800Hz ~ Muddiness area
1-6kHz ~ Adds presence
6-8kHz ~ Adds clarity
8-12kHz ~ Adds brightness
The Bass
Try boosting around 60Hz to add more body. Any apparent muddiness can be rolled off around 300Hz.
If more presence is needed, boost around 6kHz.
50-100Hz ~ Adds bottom end
100-250Hz ~ Adds roundness
250-800Hz ~ Muddiness Area
800-1kHz ~ Adds beef to small speakers
1-6kHz ~ Adds presence
6-8kHz ~ Adds high-end presence
8-12kHz ~ Adds hiss
