This can happen especially with weak signals.

In LPASS mode or BYPASS mode, the hiss will be present. It shouldn't be
there with other filters, though.

I am not sure where to fit the parts on the PC board! :-(

This would require a change in the K2 MCU firmware.

If you leave the clock displaying from the KDSP2, then press DISPLAY, you
will find the clock in the normal DISPLAY sequence just like the KAF2.  But,
to alter the DSP settings, you will have to exit the clock menu.
