As the nc400 inputs are true differential inputs, I am assuming you'd be totally OK with a simple Y cable that just has one of the nc400 input pairs reversed.
Hello Jan-Peter,
witch diagram is to be used.
Seen this one in on page 8 :

And is there a difference for the 4 ohm or 8 speakers?

If I order now will I get my amp from the wk21 batch?
Do the amps from this batch still require DC tweaking?

Is anybody else still waiting for their wk18 delivery?
Also, can somebody tell me how to open the holes on the 10mm front aluminum plate? I want to open a 19mm hole for the power button, do I use a 19mm drill or a smaller one and work my way up to 19mm?

Yes, I'm. Was told that they would ship out next week after e-mailing them.
I would have appreciated if Hypex could have written a specific message about here earlier. That would give them less e-mails to answer as well. Good for both parties.
Do this
I find that increasing the diameter in 2mm steps works quite well with a hand drill
and a vertical drill stand or bench drill also helps but isn't essential
Use nice sharp drills

Well, I placed my order week 15, and still haven't gotten a shipping confirmation. 🙁
I received mine last thursday, but I placed the order on 27th february! Already assembled and working, but don't ask me about sound quality (I'm still experimenting).
About the holes, you get a much easier and precise work with a vertical drill (a €50 chinese one is enough) and the right drill bit like this:

I tried with a cheaper wood bit too http://www.pianetautensili.it/Public/Prodotti/resize/20105894326748Localmecchialegno.jpg and it worked. It gets ruined easily, but you can sharpen it again with a file.

I ordered for delivery earlier this year but was deferred to wk18.
I have been told my order will be shipped next week.
Metalwork ready waiting

Mmm lucky me. I ordered and paid them 6 days before (21st of February). I received my 5 NCore's on the 26th of March and enjoyed them in good working order already from the 1st of April.... I should already start thinking on upgrading my amps.😀
Jan-Peter,
Perhaps you could help with the below question, which as far as I know remains unanswered.
Thanks

This question is answered once every 100 pages of this thread or so. The gist of it is, as spelled out in sections 7.2 and 8.1 of the data sheet, use a supply that shuts down when pin 5 of the power connector is pulled low. This pin is pulled low when the NC400 finds the speaker output stuck at a high voltage.
The SMPS600 has this function. If, for reasons of philosophy*, you want to build your own linear supply, add disconnect relays between it and the power amp and make them respond to this line.
DO NOT USE SPEAKER RELAYS. Speakers are inductive little buggers and will sustain an arc across the relay contact long enough for it to weld shut. Speaker relays CAN AND WILL FAIL at the exact moment that you need them.

Hi Sherlock, I have had very good results using a stepless pyramid drill, as used for automobile antennas, and using household spirit as ´drilling oil´. Use high speed and low pressure, and do it in small steps, and measure with the switch continually when you are working.File and sand smoothly afterwards.

Arthur.

I don't think that would work for a 10mm front plate
(I like pyramid drills too but on thinner sheet)
The 'tank cuttter'/'core drill' type of cutters suggested by antbom work well
