24. HIGH EQ

The high EQ provides up to
15 dB of boost or cut above 12
MAIN OUT
kHz, and it is also flat (no boost
BAL/UNBAL
or cut) at the detent. Use it to
add sizzle to cymbals, an overall
R L R
sense of transparency, or an
LINE IN 7-8 LINE IN 9-10 LINE IN 11-12
edge to keyboards, vocals, guitar and bacon frying. Turn
L L L
it down a little to reduce sibilance or to mask tape hiss.

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
