I am trying to configure above evaluation board with 8 EQ's (125, 250, ..., 16000Hz), using for the EQ “Filters, Second order, Double precision, 2 Ch, Medium Size Eq”. The only thing I have changed is the frequency of each, the remaining parameters being as the program proposes (i.e. Peaking EQ, Q=1.41).
But: Once downloaded into the 1701, the frequencies controlled do not correspond to those I have entered, but approx. to 1/4th of those.
E.g. varying gain of 1kHz, the real variation is around 250Hz. The same thing happens with all the other frequencies, e.g. the 16kHz EQ varies frequencies around 4kHz.
Am I doing something wrong here?
