get or set output EQ frequency for bass EQ band (low shelving): eqf0
get or set output EQ frequency for mid 1 EQ band (peak/dip EQ): eqf1
get or set output EQ frequency for mid 2 EQ band (peak/dip EQ): eqf2
get or set output EQ frequency for mid 3 EQ band (peak/dip EQ): eqf3
get or set output EQ frequency for treble EQ band (high shelving): eqf4
The value indicates the frequency, in Hz, for the specified EQ band. For the bass and treble bands, the frequency is
the edge frequency for the shelving EQ. For the mid bands, the frequency is the center frequency for the peak/dip
EQ. The frequency is an unsigned integer between 20 and 20000. For compatibility with the PC GUI, it is highly
recommended that the frequency set with these commands be restricted to the following values:
20, 25, 32, 40, 50, 63, 80, 100, 125, 160,
200, 250, 315, 400, 500, 630, 800, 1000, 1250, 1600,
2000, 2500, 3150, 4000, 5000, 6300, 8000, 10000, 12500, 16000,
20000
Use of other frequency values is allowed, but the PC GUI will not be able to select values other than what are
specified above.
Examples:
=s@eqf0:100!
set bass EQ frequency to 100 Hz
=s@eqf2:4000!
set mid 2 EQ frequency to 4000 Hz
get or set output EQ boost/cut for bass EQ band: eq0
get or set output EQ boost/cut for mid1 EQ band: eq1
get or set output EQ boost/cut for mid2 EQ band: eq2
get or set output EQ boost/cut for mid3 EQ band: eq3
get or set output EQ boost/cut for treble EQ band: eq4
The value indicates the boost/cut level for the specified EQ band, in ½ dB steps. The boost/cut is an integer between
-24 and 24 (-12.0 to +12.0 dB). A boost/cut of 0 dB indicates flat response (no boost or cut).
Examples:
=seq1:5!
set mid 1 EQ boost/cut to +2.5 dB
=seq4:-20!
set treble EQ boost/cut to -10.0 dB
get or set output EQ Q for mid 1 EQ band: eqq1
get or set output EQ Q for mid 2 EQ band: eqq2
get or set output EQ Q for mid 3 EQ band: eqq3
The value indicates the “Q” of the EQ filter for the specified EQ band, in
1
/
10
steps. The Q is an unsigned integer
between 1 and 100 (i.e., 0.1 to 10.0, in steps of 0.1). The Q for the bass and treble EQ bands is fixed at 0.707 and
cannot be changed. A Q of 1.5 is recommended for the mid EQ bands.
Examples:
=seqq1:8!
set mid 1 EQ Q to 0.8
=seqq2:15!
set mid 2 EQ Q to 1.5
