Re: K3 Rev C DSP with Low Freq Enhancement

[Bruce Beford-2]

Eric,

Would it be possible to release an app note listing the component value
changes you mention:

"We increased coupling caps and a few other values in the audio chain to
increase low freq audio response below 300 Hz."

This way, those of us who feel up to the task can modify our own early DSP
boards. I assume the changes are similar to, or an extension of what has
been published privately by Paul and Ed. It would be very nice to see the
"official" changes.

Thanks,
Bruce N1RX
K3 #559

It would also be interesting to compare this with the unofficial mods posted on a Russian site that have been mentioned a couple of times recently.

Personally I am quite happy with the sound of my K3 as it is now with the latest firmware. But reading about these mods make me wonder whether I am really missing out on something.
