Four-Band Equalizer

Figure 6-12 Analog Channel 4 BAND EQ

The 24 Mic/Line inputs, eight additional Line Inputs, and eight Flex-Groups 

can each access a four-band EQ. The four bands can be configured in two ways:

• Bands 1–4 are identical with standard parametric controls: Gain, Frequency, 

and Q. 

• Bands 2 and 3 are standard parametric filters while bands 1 and 4 can be 

individually set to be low- and high-shelf filters, respectively. This configu-

ration is common on many analog consoles.

The entire EQ function can be switched in/out of the DSP chain from the Touch-

screen, allowing an A/B signal comparison.

Select an analog channel and press the EQ QuickMix button to display the 

4 BAND EQ Touchscreen. The Band 1 and 4 types are toggled from light switch 

buttons. The graph summarizes the EQ settings.

Gain

Each of the four filter's GAIN is adjustable 

±15 dB in 0.1 dB increments. Each 

band defaults to zero gain.

Frequency

The FREQ parameter determines the filter’s center frequency, at which the gain 

setting is applied. FREQ is adjustable from 20 Hz to 20 kHz in scaled steps. For 

shelf-filter bands, the FREQ setting designates the half-power frequency: the 

frequency at which the power has decreased to half its maximum.
