Use -5 it to add sizzle to cymbals, an -10 -15 overall sense of transparency, 20Hz 100Hz 1kHz 10kHz 20kHz or an edge to keyboards, vocals, guitar and bacon frying. Turn it down a little to reduce sibilance or to mask tape hiss. 25. MID EQ FREQUENCY (Ch. 1-4) This knob sets the center frequency of the mid EQ level control [26]. This is sweepable from 100 Hz to 8 kHz. Once this is set, the mid EQ level can be adjusted with the mid EQ level control. Most of the root and lower harmonics that define a sound are located in the 100 Hz-8 kHz frequency range, and you can create drastic changes with these two knobs. Many engineers use mid EQ to cut midrange frequencies, not boost them. One popular trick is to set the mid fully up, turn the frequency knob until you find a point where it sounds just terrible, then back the mid down into the cut range, causing those terrible frequencies to disappear. Sounds silly, but it works. Sometimes. 26.

LOW EQ OO 34 SOLO 1 SOLO 2 SOLO 3 SOLO 4 SOLO 5-6 The low EQ provides up to +15 15 dB of boost or cut below +10 +5 80 Hz. The circuit is flat at the 0 center detent position. This -5 frequency represents the punch -10 -15 in bass drums, bass guitar, fat 20Hz 100Hz 1kHz 10kHz 20kHz synth patches, and some really serious male singers who eat raw beef for breakfast.
