Polycom Vortex EF2280 User Manual

input channels 1-8 and A-D . Each channel has five bands of parametric EQ that can be independently controlled.
For the Linkwitz-Riley filters, the slope can either be 12 or 24 (dB/Octave).For the low shelf and high shelf filters,
the minimum value for the slope parameter is 1, and the maximum value is 1.2 times the current value of the
gain parameter. See the
PEQIG command for information on the gain parameter.
This command has the same format and restrictions as the
PEQIA command except that only one parameter, the
slope, is specified instead of all the parameters. See the
PEQIA command for more information. To set the slope
parameter for an output parametric EQ filter, use the
PEQOS command. To set all the parameters for an output
parametric EQ filter, use the
PEQOA command.
This command is saved to non-volatile memory only as part of a preset. The state of this command will be
restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description Status Message
F01PEQIS3,2,1
Set the slope of the parametric EQ on
input 3 , band 2 to 1 dB per octave.
F01PEQIS3,2,1
F01PEQISB,1,?
Query current slope setting of
parametric EQ on input B , band 1.
F01PEQISB,1,s , where s is the current setting of
the slope parameter for the parametric EQ on input
B , band 1. If the slope parameter of this filter is set
to the same value given in the example above, then
the status message will be F01PEQISB,1,1 .
8.109. PEQIT -- Set Type Parameter for Specified Parametric EQ
Input Stage
This command sets or queries the type parameter for the parametric equalizer (EQ) filters on input channels 1-8
and A-D . Each channel has five bands of parametric EQ that can be independently controlled.
The type parameter specifies what type of filter is executed for the specified band of the specified input channel.
The different filter types and their corresponding values are shown in the table below.
Filter Type Value of Type Parameter
Parametric 1
Low Shelf 2
High Shelf 3
Lowpass 4
Highpass 5
Linkwitz-Riley Lowpass 6
Linkwitz-Riley Highpass 7
This command has the same format and restrictions as the
PEQIA command except that only one parameter, the
filter type, is specified instead of all the parameters. See the
PEQIA command for more information. To set the
slope parameter for an output parametric EQ filter, use the
PEQOT command. To set all the parameters for an
output parametric EQ filter, use the
PEQOA command.
