The current equalisation curve shown on the display should be
thought of as being in a scratchpad or working area. A curve can be
recalled from a program memory and then adjusted in the working
area without altering the stored program memory. If the curve is edited
wrongly, the program memory can be recalled again or FLAT pressed
to start again. Only when a curve is adjusted correctly in the working
area need it be stored into a more permanent program memory.
Pressing the strip in an area of the curve where there are no filters will
move a spare filter to the chosen frequency. The filter values in the
status bar change to reflect the new frequency and the cursor moves to
the new position. Adjusting the filter Cut/boost using the rotary control
will change the displayed curve and a new arrowhead will appear at
the bottom of the cursor to mark the filter and the filter adjustment
will be sent to the currently selected Varicurve device. If the speed
strip is pressed close to a currently used filter marker, that filter will be
selected and marked with the cursor. When there are two used filters
close together, pressing the speed strip repeatedly near them will step
the filter cursor between them alternately.
Each of the three filter parameters has a separate rotary control on the
900r making it even easier and quicker to adjust filters than the FCS-
926 Varicurve.

Turning the FREQUENCY control will move the centre frequency of
the selected filter. The exact frequency of the peak or dip is
displayed in Hertz (Hz) in the status bar FREQ: box. The adjustment
range is from 20.7Hz to 20kHz.
$
Turning the WIDTH control will broaden or narrow the selected
filter bandwidth. The width of the filter is displayed in octaves (Oct)
in the status bar WIDTH: box. Adjustment is from 0.1 to 2 octaves.
$
Turning the CUT/BOOST control will increase or decrease the gain
of the filter at its centre frequency. The filter cut or boost is
displayed in dB in the status bar BOOST: box. The range available
is from +15dB down to -15dB. Turning the control past -15dB will
change the filter to become a deep notch of around -30dB. The
BOOST: status box will indicate ‘Notch’ in this mode.
