What is missing for the next official release is the FIR/IIR mix. I'm also looking at some more enhancements of the GUI.

There is probably something wrong about your approach to input gain. Normally, you should set the output level of your digital sources to 0 dB. This way you ensure that full resolution audio is feeding the DSP. Then you should set the analogue gain on your source such a way that the signal is near to full scale in the ADC. The clipping led will help you to set the appropriate gain.
If you proceed like this, then all you signals take profit of the full dynamic range and you don't need to set different gains on the DSP.

The 0db I am aware of,but the optical and the analog source dont have variable level only the laptop.

Hej Åke.
Have you tried turning of the "bass/treble" option ? Under settings.

Best regards. Bengt

Yes, the bass/treble is off.Wondering if it has sommething to do with the post gain (and pre gain)?How they are in relation to each other.

Here's a photo of my Najda. I've now got the hard work of sorting out the filters, but I'm really pleased so far. Thank you so much! (NB: I used the Meanwell 35B power supply - it seems to work well. The 'buttons' are all spring return switches - the up/down and left/right being two way. I've yet to do the IR. The LED is from eb@y - despite the fact that I live in HK, sourcing that was painful!)

The Najda is now playing music through my "big" DIY speakers (Seas T25CF002, prop 6.5" mids and prop 12" woofers) with my three channel LM4780 amps. If it works out I'll build another amp that will be 6 channels in one.

For some reason the IR receiver is not working but I'm sure that's my fault so I'll fixa that later. First I want to adjust the Najda for a rough initial setup. So far I'm just testing with woofers crossed at LR24-80Hz, mids at LR24-80Hz/2500 Hz and highs at LR24-2500 Hz. Sounds pretty good so far.

Excellent stuff Nick!

Nice to hear that your getting the builds to work.

But one problem here is that the clip warnings don`t turn on instead I get a cracking sound if the digital level seems to high,don`t how yours Nadja does?
