If the L/R and MONO outputs are linked, they share 

the same EQ and compressor settings. If unlinked, they 

have independent settings. If they are unlinked and 

then linked, the MONO output inherits the L/R settings.

6.4 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 configuration is 

common on many analog consoles. 

The entire EQ function can be switched in/out of the 

DSP chain from the Touchscreen, 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 but-

tons. 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. 

The default frequencies for each band are: 

•  Band 1: 80 Hz  

•  Band 2: 500 Hz  

•  Band 3: 2 kHz  

•  Band 4: 10 kHz
