The K3 filter is a little unusual in that the receiver equalizer is part
of the DSP bandpass filter, not a different or subsequent filter. This
helps minimize latency.
As a result, the equalization is applied before the audio paths are
separated, so it is on all receive paths.
In data modes, the equalizer is disabled (the filter coefficients are
re-computed ignoring the equalizer settings).

Prob the first 3. The 4th is mostly for digital and thus not needed.

I understand that the K3 has two separate equalizer settings for CW and
SSB. I also understand it is not active in the Data modes.
However, there are four sources of audio output:
1) Internal Speaker
2) SPKRS (rear panel)
3) Phones (front panel)
4) Line Out (rear panel)
Does the equalizer operate for all four outputs?
