Can do, no problem.
I actually happen to have an encoder lying around (this model http://www.adafruit.com/datasheets/pec11.pdf).
I'll report how it goes by mid-December (in the meantime I'm busy with some other stuff eg NUC control application and analogue expansion).

NUC 1.0.2 tests
I tested NUC 1.0.2 and find it not updates settings to device in Synced state. First all works OK but after 10 or something change times new parameter changes where not updated to DSP.
I get them working only when saved preset ot DSP memory, reset DSP and load presest from DSP memory with DSP keypad.
I made just ordinary IIR settings and 3 channel filters, DSP core loads where about 50%.
Can it be PC problem or... monitoring was working fine when parameters where not updated.
One question also: how long is output channel processing delay, how to calculate it and did this delay need also compensation if different channels had different processing delay?

Hi Meelis,
I'll have a look at this. Is there a procedure that I can repeat so that I can observe the same behavior? I don't believe this could be connected to your computer.
The input/output delay in the channel processing flow is 1 sample (provided the delay is set to 0). This applies to all channels.
Hi,
I have had this issue 4-5 times the last 6 months. Especially if Najda has been in standby for a long time. I Wonder if it started after I changed to the Meanwell 35B. It does not help to push the Remote or stby button on Najda. I have to remove the mains Power from the Power supply.
best,
Paal
Back to this issue you've reported. I've just uploaded NUC v1.0.3 BETA. It includes several changes related to pairing, maybe solving your problem (maybe not).
Please note that this is a beta release as not fully tested.
Hi Paal,
No I don't think this could be related to your power supply. Thanks for reporting, I'll try to reproduce that.

What I did was: Made changes in IIR settings (mainly PEQ) made measurement of results and on about 10ths time I start to measure new changes, I realised that changes in NUC where not updated to DSP.
Thanks Meelis. I'll investigate and try to reproduce the bug. If you can try the latest version (1.0.3) and see if it still happens, that would be quite helpful.
Sorry if a little OT. Just interested to know what Najda users are doing for interconnect solutions. Eight cables to the amps attached to my speakers - that is about 30-40mtrs of cable🙁
Apart from cost, the bulk of the cable is ugly in itself. Hence I am thinking about Cat5 in my desperation.
Suggestions welcome.

Good to know it works in a decent set-up like that, thanks. I can see the first challenge is a good connection to the RCAs without it snapping - maybe avoid solid core therefore, go for multi-stranded, and research heavy duty Cat5.
Multi-stranded is good anyway unless you nail down the cable. My system has cat 5 connectors, but if you are stuck with RCA's, I would suggest a wood or particle board plate with a cable clamp to attach the cat5 cable to (to remove strain from the cable), and splitting off the individual twisted pairs to RCA's from there.
I'd say that terminating CAT5 AND making it look even half decent will be hard. I use a triple RCA aka "component" cables and place my amps close to the speakers. The fact that those cables are stuck together from the Najda all the way to the amps make it look quite neat. If you have 4 channel I'd simply use two stereo cables. IMHO it's not a big problem and a great component cable is easy to find for USD 25-30 or so.

Najda can come with RCAs not connected I recall. I have not ordered yet since this is a consideration. I could then use Cat5 connectors, very tidy.
Two stereo cables, of decent quality, will be expensive and more bulk then I care for.

Not sure if thera are any options yet as I seem to recall that all orders so far have been for Najda WITH the volume control chip and connectors and thus the only options right now is "standard". That might have changed though.
Obviously you are making you own choices but I really can't see how two stereo cables could be sigificantly more bulky or more expensive than CAT5 connectors and cables. The difference must be hardly noticeable. Then again, there are ways one can spend lots of money on cables if so inclined.

I have seen one build picture with the RCAs not connected - I hate desoldering - so hopefully Nick can confirm.
Cost for 5 channel (one too many, I know) terminated cable as an example - two times 5 meter cables is £232
Belden 1694A Multi-Channel Audio Cables
Multichannel Audio Cables at Blue Jeans Cable
Obviously two 5 meter lengths of Cat5 is not £232. Cat5 definitely the frugal option. Bulk may be subjective but I Cat5 is tiny in comparison.

Right, as I suspected there are indeed ways of spending lots of money. For me it was about GBP 50 for RCA cables including speaker wires. In total. That would be about the same as CAT5 stuff give or take. On the others hand it seems a bit odd to compare really expensive cables with "almost for free" cables. However, there are really excellent build quality cables that would set ju back about GBP 60 for four 5 m lenghts of stereo cables. That comparison would be a bit more fair IMHO. So for me CAT5 is not frugal but an akward and extremely sub optimal solution as I can get studd ready-made and just plug in without any hassle. We do however have the opportunity to make any decision we want.
I'm sure Nick will chime in and let us know if there are Najdas without connectors.

Yeah, ready made is expensive, though the raw materials are not cheap either. I'd make my own probably whatever way I go. My amps have no connectors currently so I am open to hearing any alternative ideas from Najda builders.
