2 LO MID VARIABLES

LO MID Variable 1: Boost/Cut

LO MID Variable 2: Band Center

Fig. 2

boost or cut of this section, through a range of ±15dB, is set with the top knob. The center frequency is dialed in with the middle knob, and can be set anywhere between 500Hz and 18kHz. Finally, the bandwidth of the bell-shaped response curve around the selected frequency (also somewhat inaccurately referred to as a ratio known as Q) can be selected with the lower knob. The range is from as wide as 3 octaves to as narrow as 1/12 octave. Leave it at the center

detent if you are unfamiliar with the bandwidth feature. This setting will give you a semi-parametric type of EQ.

The 8•Bus console’s set of three HI-MID controls (boost/cut, frequency center and bandwidth) is VERY powerful in its effects. Rarely if ever will you need more than a few dB of boost and cut or, as noted above, will you want to stray from the NORMAL (2 octave) bandwidth until you gain some experience recording and mixing.

The LO MID EQ section is called a semi-parametric equalizer, because the bandwidth is not adjustable (Figure 2). The frequency range is 45Hz to 3kHz and the bandwidth is fixed at 2 octaves.
