Peqoa -- Set All Parameters For Specified Parametric Eq Output Stage - Polycom Vortex EF2280 Programming Manual

restored after power-up only if a preset is saved and that preset is set to be the power-on preset.
Example Description
Set the type of the parametric EQ on
F01PEQIT3,2,1
input 3 , band 2 to parametric.
Query current type setting of
F01PEQITB,1,?
parametric EQ on input B , band 1.
8.110. PEQOA -- Set All Parameters for Specified Parametric EQ
Output Stage
This command sets or queries all of the parameters for the parametric equalizer (EQ) filters on output channels 1-
8, and A-D . Each channel has five bands of parametric EQ that can be independently controlled.
The output parametric EQ filter parameters can be set individually via the PEQOT, PEQOF, PEQOB, PEQOG,
PEQOS, and commands. The input parametric EQ filter parameters can be set simultaneously via the
PEQOE
command or individually with the PEQIT, PEQIF, PEQIB, PEQIG, PEQIS, and
PEQIA
When using this command, you must specify all of the following parameters.
Description Value Range
Channel 1-8, A-D
Band 1-5
Filter Type 1-5
Frequency 20 - 20000
Bandwidth 5 - 200
Gain -20 - 20
Slope 1 - 1.2 * Gain for shelving filters, 12 or 24 for Linkwitz-Riley filters
Enable 0 - 1
The paramters are specified in the order shown and are separated by commas. The wildcard character, *, may
not be used for any of the parameters listed above. If an attempt is made to set one of the parameters outside
the valid range, the command will fail and return an error message of ERROR#002.
Not all of the parameters are valid for each of the filter types. The following table shows which parameters are
used in each of the filter types.
Status Message
F01PEQIT3,2,1
F01PEQITB,1,t , where t is the current setting of
the type parameter for the parametric EQ on input B
, band 1. If the type parameter of this filter is set to
the same value given in the example above, then
the status message will be F01PEQITB,1,1 .
