2.3 EQ Controls
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.
