One of the most exciting aspects of using a mixer such as the MIXPAD is the ability to shape a sound, using a process called equalization. But there are few areas of sound engineering more misunderstood than equalization, and, just as good EQ can really help a sound, bad EQ can really hurt it, so read on...

Every naturally occurring sound consists of a broad range of pitches, or frequencies, combined together in a unique way. This blend is what gives every sound its distinctive tonal color.

The EQ section in a mixer allows you to alter a sound by boosting or attenuating specific frequency areas. The MIXPAD 12 and MIXPAD 9 both provide independent two-band equalization controls for each of their input channels, while the MIXPAD 4 provides independent three-band equalization controls for each input channel.

In all models, the EQ controls in stereo channels affect both input signals identically.

the MIXPAD 4, ±12 dB in the case of the Mid

frequency). In the MIXPAD 12 and MIXPAD 9, the

High EQ knob affects frequencies above 10 kHz, while the Low EQ knob affects frequencies below 100 Hz (with both using a shelving curve). In the MIXPAD 4, the High EQ knob affects frequencies above 12 kHz, while the Low EQ knob affects frequencies below 80 Hz (with both again using a shelving curve). The MIXPAD 4 also provides an additional Mid EQ knob, affecting frequencies around 2.5 kHz (using a bell, or peaking curve). We provided these particular frequency areas because they have maximum impact on musical signals—that’s why they are sometimes known as “sweet spots.” When an EQ knob is in its center detented position (at “0”), it is having no effect. When it is moved right of center, the particular frequency area is being boosted; when it is moved left of center, the frequency area is being attenuated.
