Help with using FilterPro

[Aladin_Rj]

I am trying to make an active bandpass filter with the frequencies of 300Hz and 12000Hz, however I can not configure the filterpro, I am from Brazil and I can not understand the video of ti that is in English. Could anyone tell me how to configure these frequencies in FilterPro?

A bandpass with 300 Hz and 12 kHz cut-off frequencies should be designed as combination of separate high- and low-pass filters. Define the required filter steepness, select a suitable filter characteristic, in case of doubt Butterworth and you are done.
