Mid Eq Controls: Level And Freq - Alesis Studio 24 Reference Manual

Description of Controls
MID EQ
For Channels 1 - 8, the Studio 24 features a "semi-parametric midrange", which
means that you can control some of the parameters or aspects of the midrange, besides
just cutting and boosting a predetermined frequency range. Combined with the
HIGH and LOW EQ controls, these make up a 3-band equalizer that can create the
vast majority of tones you may need.
The Mid controls consist of two knobs: FREQuency and MID gain control. Notice
that the FREQ control is a lighter shade of green, to help you identify it.
The FREQ knob changes the center frequency of the EQ. The range is sweepable
between 120 Hz (bass) to 13 kHz (extremely high treble).
The MID 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.
To learn how the midrange EQ works, put some broadband material (like a CD) into
a channel at a low level. Boost the mid level to its maximum, 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.

The Stereo Channels have only a fixed midrange boost/cut knob. These Channels
accept only line-level inputs, and a Frequency control is usually not necessary when
equalizing electronic instruments.
