provided mainly as guidelines for programmers writing control software for the Vortex. If a parameter is not 
valid for a specific filter type, then the control for editing that parameter should be disabled or removed 
when that filter type is selected. 
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
B01PEQIA3,2,1,1250,40,-20,1,1
Set the parametric 
EQ on input 3 , 
band 2 to the 
following 
parameters: type = 
parametric filter, 
frequency = 1250 
Hz, bandwidth = 
40 1/100th 
octaves, gain = -20 
dB, enabled = yes, 
slope = 1 dB per 
octave. The value 
of the slope 
parameter is 
irrelevant for this 
type of filter, we 
could have set it to 
anything. 
B01PEQIA3,2,1,1250,40,-20,1,1
B01PEQIAB,1,?
Query the current 
parameter settings 
for the parametric 
eq filter on input B 
, band 1. 
B01PEQIAB,1,t,f,b,g,s,e , where the 
parameters t, f, b, g, s, and e correspond to 
the current settings of the type, frequency, 
bandwidth, gain, slope, and enabled 
parameters, respectively. If this filter was set 
to the same parameters as given in the above 
example, the status message would be 
B01PEQIAB,1,1,1250,40,-20,1,1 . 
8.119. PEQIB -- Set Bandwidth Parameter for Specified 
Parametric EQ Input Stage
This command sets or queries the bandwidth parameter (in 1/100th octaves) for the parametric equalizer 
(EQ) filters on input channels 1-4, A-D, and T . Each channel has five bands of parametric EQ that can be 
independently controlled. 
The minimum and maximum values for the bandwidth parameter are 5 and 200, respectively. 
This command has the same format and restrictions as the 
PEQIA command except that only one 
parameter, the bandwidth, is specified instead of all the parameters. See the 
PEQIA command for more 
information. To set the bandwidth parameter for an output parametric EQ filter, use the 
PEQOB command. 
To set all the parameters for an output parametric EQ filter, use the 
PEQOA command.
