You can think of the RTA-31 as being comprised of two separate
panels: the EQ Panel and the Analyzer Panel. There is also a
reduced view (Shrunk Screen) that collapses the plug-in window
into the minimized control strip.
The 31-Band Graphic EQ section of the GUI (graphic user
interface) is a fully functional 1/3-octave frequency EQ
controlled by a series of linear sliders. These sliders may
attenuate only (band cut) or, more typically, attenuate and boost
(band cut/boost) the frequency response curve of a given signal.
This can help to reduce resonating peaks and dips associated
with live sound systems and acoustic environments. It does so
by eliminating feedback and other unwanted noise as well as
shaping the frequency response of your mix.
The thirty-one bands of EQ range from 20Hz to 20kHz. Each
band allows for –12 dB to +12 dB of level. All of the linear
sliders can be adjusted up or down independently. The
adjustment of the sliders can have a dramatic or subtle effect on
the EQ depending on the amount of boost/cut applied.
There are four adjustment modes for the EQ sliders (Sweep,
Single Set, Sweep Default, and Sweep Copy). These modes
adjust one or more of the bands at a time. Sweep is the feature
that lets you adjust more than one band at a time using your
mouse in conjunction with selected key commands.
