Hello,

I have purchased recently a JA11 dongle, that works great.

However, there is a bug either in the Fiio control app or in the dongle itself.

When i set custom EQ filters, the frequency i enter in the Fiio control app gets doubled when i save the filters to the JA11.

example:

if i set a peak at 1 kHz and i save it to the JA11, then i measure the frequency response of the JA11, the measurement shows a peak at 2 kHz. If is set a peak at 3 kHz, i measure a peak at 6 kHz, and so on.

The same happens to shelf filters.

Another owner of the JA11 has confirmed the same bug in his unit.

Firmware 1.7 does not solve the issue.

Could you please help to solve this bug?

thanks!
