This command has the same format and restrictions as the
PEQOA command except that only one parameter, the
filter type, is specified instead of all the parameters. See the
PEQOA command for more information. To set the
slope parameter for an input parametric EQ filter, use the
PEQIT command. To set all the parameters for an
input parametric EQ filter, use the
PEQIA 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
F01PEQOT3,2,1
Set the type of the parametric EQ on
output 3 , band 2 to parametric.
F01PEQOT3,2,1
F01PEQOTB,1,?
Query current type setting of
parametric EQ on output B , band 1.
F01PEQOTB,1,t , where t is the current setting of
the type parameter for the parametric EQ on output
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 F01PEQOTB,1,1 .
