Equalizer

The possibilities that an equalizer provides when working with the Mid or Side signals corres-
pond to the normal applications of an EQ, the full scope of which is beyond our purpose.

Two  of  the  most  common  functions  of  an  EQ  ought  to  be  more  than  enough  to  illustrate 
the potential of using it as an INSERT: attenuation of low frequencies and boosting of high 
frequencies.

Among the most common problems of a mix are booming synth pads and guitar walls with a 
very deep frequency response. They can make a Side signal too dense or clash with important 
low frequency signals – like bass guitar and bass drum – usually found in the Mid signal. With 
an EQ in the MID and/or SIDE INSERT you can focus on that specific frequency range in order 
to  avoid  conflicts.  The  Mid  signal  is  thus  cleansed  and  the  primal  elements  become  more 
precise and distinguishable. Selective EQ can give the Side signal more air, making cymbals 
and harmonic instruments sound more present without adding too much sharpness to vocals.

Increasing high frequencies in the Side signal usually results in a wider stereo image with a 
solid center image.

Another interesting possibility is the processing of individual elements of a mix to affect posi-
tioning. The depth of a signal is strongly influenced by high-frequency, monophonic diffe-
rences, which are then shaped by the ear. Sounds above 1.5 kHz coming from in front of the 
receiver are more intensely reflected by the ear and are responsible for a good directivity. In 
this situation, an EQ can be used to process the frequency range in question (generally spea-
king, this will affect Mid signals so you will have to use the MID INSERT). Signal presence is 
intensified by emphasizing frequencies between 1.5 kHz and 2 kHz, which results in a small 
increase in the overall level.
