Description of Controls
The MID GAIN knob controls how much boost or cut is applied to the band chosen.
At the center detent position, there is no effect (flat response). Turning to the right
amplifies the band, to a maximum of 15 dB. Turning to the left cuts the band, to a
maximum cut of -15 dB.
The Q, or bandwidth, can be adjusted to select the range of frequencies around the
center frequency that will be most affected by the boost or cut. It can be set to as
little as 1/6th of an octave when turned completely left, or to almost 2 octaves
when turned completely clockwise.
To learn how the midrange EQ works, put some broadband material (like a CD) into
a channel at a low level, and press the EQ IN switch down. Boost the mid level to
its maximum, turn the Q control all the way to the left, and then sweep the FREQ
control to hear the effect. You usually won't use such a dramatic EQ setting on a
mix, but it will help you get acquainted with the center frequencies this affects.
