Low Band Frequency: Sets the center frequency of the EQ’s low-frequency band. You

can adjust the center frequency from 20 to 250 Hz.

Low Band Gain: Sets the attenuation or boost of the EQ’s low band. The gain can be

set between -16 and +16 dB.

Low Band Peak: When the Peak switch is engaged, the low band of the EQ becomes

a standard peak ﬁlter with a ﬁxed Q of 0.6. When it is disengaged, the low band is a

shelving ﬁlter.

Power User Tip: A shelving EQ attenuates or boost frequencies above or below a

speciﬁed cutoﬀ frequency. In practice, these types of EQs are much like the treble

and bass controls on your car stereo. Like a bass control, a low-shelf ﬁlter will raise

or lower the gain on all frequencies below the speciﬁed cutoﬀ frequency. A high-

shelf ﬁlter will raise or lower the gain on all frequencies above the speciﬁed cutoﬀ

frequency, just like a treble control. Shelving EQs can be used to make big changes to

the sound very quickly by adding or removing an entire range of frequencies at once.

In contrast, a peak EQ oﬀers continuous control over the center

frequency of the band and of the level (boost/ cut) of the designated

frequency band, which makes it capable of more subtle changes.

Low Mid Band Frequency: Sets the center frequency of the EQ’s low-mid frequency

band. You can adjust the center frequency from 160 Hz to 2 kHz. The low-mid band

has a ﬁxed Q of 0.6.

Low Mid Band Gain: Sets the attenuation or boost of the EQ’s low-mid band. The

gain can be set between -16 and +16 dB.

High Mid Band Frequency: Sets the center frequency of the EQ’s high-mid band. You

can adjust the center frequency from 800 Hz to 8 kHz. The high-mid band has a ﬁxed

Q of 0.6.
