This dialog box provides the means to remotely control many of the functions of 1/3 octave equalizers, and also provides automatic control and optimization of the equalizer bands to achieve a predetermined target response curve. Manual control of the EQ is also possible, as well as manual operation of the RTAjr analyzer.

The RTAjr can be used to automatically adjust the EQ band levels to match the response measurement to a previously defined target curve entry. The curve entry to be used as the target is selected in the Library Curve Entry for Target list box. This could be a flat line, or any other shape desired.

The PA-422 interface is a serial port protocol standard which is used by several different audio manufacturers for their programmable signal processing equipment. This routine was characterized with the MicroAudio 2.2CQ and White 4700-2 1/3 octave stereo equalizer units. While the PA-422 spec defines the protocol of communication, most PA-422 equalizers will generally still require specific configuration due to their unique parameter tables. The Rane RW-232 is also supported.
