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
T01PEQOTT,2,1
Set the type of the parametric EQ 
on output T, band 2 to 
parametric. 
T01PEQOTT,2,1
T01PEQOTT,2,1
Query current type setting of 
parametric EQ on output T, band 
1. 
T01PEQOTT,1,t, where t is the current 
setting of the type parameter for the parametric 
EQ on output T, 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 T01PEQOTT,1,1.
