Press the GEQ Fader Flip key to view and adjust the
GEQ on the faders while a mono or the LR mix is
selected. The screen highlights the active range of
frequencies. Press the switch again to change range
or return to normal mix mode.
The faders toggle between the lower and higher
ranges of frequencies with a useful overlap. The
frequencies are shown on screen and marked on the
panel above the faders.
The fader strip Sel key turns on when the slider is at
0dB mid (flat) position while in fader flip mode. Press a
Sel key to return a slider to 0dB.
It is better to cut rather than boost frequencies when
tuning speakers using the GEQ.
