EQ Controls
Press and hold a fader’s A/B button and the Input Tab opens. Click the EQ button
on the Button Bar at the bottom of the Input screen to display the EQ screen.
To change parameters in the Control Area, click on the Value Window for the param-
eter you wish to change. Then use the INPUT SOURCE knob on the Master Panel to
turn the value up or down as desired. You can also click on the parameter’s slider and
move it up or down.
In the upper part of the screen are the graphical EQ display and VU meters. The stan-
dard audio frequency of 20Hz – 20kHz is ranged in logarithmic form across this graph
with gradations at salient frequencies. The vertical axis scale range is -15dB – +15dB,
with gradations every 3dB.
The level meter is a dual-indicating peak-over-average, with peaks riding as a lone
“dot” over a solid bar-graphed average. An “Over” indication is at the top of the input
level bargraph.
The EQ system consists of a four-band parametric EQ with low band and high band
PEAK/SHELF switching, plus variable frequency high and low pass filters. As any of
the controls are adjusted, a real time graphic display shows the resulting frequency re-
sponse curves.
