FxSound Equalizer


Multiband equalizers allow you to selectively boost or cut the audio energy present in multiple frequency ranges of your music and these frequency ranges are referred to as “bands”. Making adjustments to the sound energy in these bands compensates for imperfections in the frequency response of your playback system and environment. These imperfections cause some bands of your music to have their energy levels attenuated while other bands will be accentuated.


The FxSound EQ is a substantial tool to help personalize your audio playback system to best suit your playback environment and personal tastes. As a first step we recommend selecting the FxSound Preset that sounds best with your music. It may be that you find different presets that you like with different types of music, which is common.The FxSound EQ then allows you to further tune your sound system to your personal tastes.With your favorite FxSound Preset selected, using the descriptions above, experiment with the settings in each band to learn how they affect the music and to find the settings that sound best to you.

Note the FxSound EQ displays the center frequency of each band underneath each control and these frequencies start at low values on the left end and move to high values on the right end.Each control will either increase or reduce the music energy in its band with the center setting of zero meaning no change. The boost or cut values are in dB (decibels) and a boost of 6dB approximately doubles the sound level in a particular band while a cut of - 6dB approximately cuts the sound level in half.

Deep Bass and Upper Bass Adjustments

The very lowest controls will boost or cut bass frequencies, typically including bass guitars and the bass drum from drum sets, including both acoustic drums and electronic drum machines. Many older recordings don’t have much deep bass energy levels and the 110Hz control is useful to boost or cut the bass level on these kind of recordings. Also with some lower cost speaker systems you will find the bass to be too “boomy”, giving a loud but not deep bass sound that can distract from the music. In this case decreasing the 110Hz control will decrease the boominess of the bass sound.

Lower Midrange Adjustments

The 220Hz and 400Hz controls allow you to adjust the music energy levels in what is commonly referred to as the “lower midrange”. Increasing these controls, in particular the 400Hz control, can result in what in a warmer sound to the music. However you may have some recordings with what is often described as a “muddy” sound, in this case reducing these controls will eliminate that muddy sound.

Midrange Adjustments

The 2.5kHz and 4.5kHz controls allow you to adjust the music energy levels in what is commonly referred to as the “upper midrange”. Adjustments in the upper midrange nicely complement adjustments of the midrange described above as the audio energy in the upper midrange will primarily be filled with the higher frequency components of vocals, guitars, piano tones and similar instrumentation. This range also heavily affects the level and attack of drums and other percussive instruments. Increasing the controls in this range will increase the impact of both vocals and drums.In some cases if vocals have too much of nasal quality or the drums sounds are too dominant in a song then decreasing these controls will help.

High Frequency Adjustments

The 8.5kHz and 16kHz controls allow you to adjust the music energy levels in the high frequency range. These controls tend to adjust the overall high frequency presence of the sound rather than directly impacting specific instruments. The 8.5kHz control covers the majority of the high frequency range that is highly apparent to your ears while the 16kHz control has an audible but much less impactful effect. The 8.5kHz control can generally be described as impacting the brightness of the sound while the 16kHz is often described as controlling an “airiness” quality of the sound. Music that sounds too dull and lifeless can be improved by increasing these controls while music that sounds too hard and brittle can be improved by reducing these controls.
