The filter order specifies the change in level relative
to the frequency, i.e., it indicates the “slope” of the
frequency curve. The high-end filter order indicates
the level decrease at the high end of the frequency
curve. A first-order filter decreases the signal level
by 6 decibels per octave (dB/oct). An “octave” is the
point where the frequency is doubled (octave above)
or halved (octave below). Each filter order decreases
the slope of the level change by -6 dB:
1
st
order:
6 dB/oct
2
nd
order:
12 dB/oct
3

order:
18 dB/oct

th
order:
24 dB/oct
The maximum slope available is -24 dB/oct, i.e., a 4
th
order filter. Press “Enter”. The symbol indicates
that the new setting has been applied.
