Agree. I have a HTPC from the same company with a very similar case.That is one cool case... It's got enough floor area but the height specification is unclear.
It says 6 cm height, but you are probably questioning if that's the internal or external dimension?
HFX - HFX mini storage
Would be awesome if it could fit.
Well... Something of the sort could be done but if we are to avoid having to add a standby supply it'd have to be connected to the primary side. Which means: properly insulated wiring and switch, and potential difficulty explaining to people that the pushbutton connection is dangerous live. I think we have to mull that one over.If the capability of using your push button switch was built into the SMPS's, just like in the separate soft start module, that would be perfect 🙂
Pretty critical I'd say 🙂It says 6 cm height, but you are probably questioning if that's the internal or external dimension?

If I buy some soft start modules and go that route, what do i do to bypass the soft start section (since the SMPS already has one) and just use it for it's switching capability. Maybe I'm wrong but it seems that adding unnecessary elements into the signal path, would subtract the advantages of using high end power cables, connectors etc.

Pretty much. It's used to program the microcontroller.(Is this where we hack into the Matrix or something...)
There's nothing left to bypass since the relay already does so.If I buy some soft start modules and go that route, what do i do to bypass the soft start section (since the SMPS already has one) and just use it for it's switching capability.

Ah... so we can expect software updates then ? 😀

Ahhh I see. So after the soft start absorbs the energy surge, a relay kicks in and completely bypasses everything as if it's a direct connection to the mains? Excuse my ignorance, this is all new to me 😕

1 final question and I will shut up (for now 🙂 ) If I want to connect 2 SMPS600's to a single soft start module, would I connect 1 to the F5-F6 output and 1 to the F7-F8?

Oh, we are likely to see those who will modify the software for "improved sonic performance" you see. We see that over on the Squeezebox Touch forum, where wild claims are made for dramatic improvemens by adjusting the thread priority in the firmware .... yeah right.
That's the alternative - add a standby supply to the smps with (possibly) a jumper to enable/disable it.Well...

We could then use that to power external control circuitry without having to install/connect a 2nd mains device

@bavmike the 2 pairs are parallelled directly.
@StigErik. You know you've just scared me out of my wits, don't you? Anyhow I'm not going to release the source code. I think Logitech have called this sort of thing up over themselves through their semi-open source policy. It's amazing though that some people can understand enough about the box to tinker with the software whilst not understanding that so long as there aren't any actual glitches in the data there's nothing to improve. There is certainly a possibility that the changes in processor load modulate the clock oscillator via the supply, but juggling thread priorities isn't going to fix that.
Should anyone have plans: the firmware on the NC400 does nothing with the amplifier other than turn it on and off. Its only job is working out when to do so.
@ChrisPa I'm not sure if we want to weigh the product down with a standby supply as standard. We'll do a bit of brainstorming here once the joint gets rolling again (january 2nd).

Hello,
In my simple setup the toroids (Reichelt -> cheap) buzz mechanically (off if switched off 😉 ) and magnetically into the DCX2496 - annoying:
04.07.2005: 4-Kanal-Amp mit Hypex UcD180 komplettiert
Only distance helps.
But the softstart with very low relaxation time and without NTC works quite well and reliable:
UcD180_Softstart
Bruno:
I measured the out voltage of one PSC2.400 directly at the board connectors:
HF: ~20...25mV (decreasing tendency after a while)
LF: ~430mV
I would like to correct it by myself, if allowed. We can discuss it by Email, if you want.
Thanks!
Happy New Year!
...Usually the dangerous bit of a toroid is where the wires come out. So make sure they are long enough so you can rotate them away from whatever bit is picking up hum.

Bruno, I can't believe you just wrote that 😱 never underestimate the amount of insane audiophile tweaks an otherwise perfectly down to earth person would do.It's amazing though that some people can understand enough about the box to tinker with the software whilst not understanding that so long as there aren't any actual glitches in the data there's nothing to improve.
don't tell me you've never seen those "Linux sounds better than Windows" or "foobar sounds better than Winamp" discussions...
Happy New Year folks
There could be a hint of truth in those. ITunes for instance is known to do sample rate conversion by the simple expedient of dropping or repeating samples. I'm not making this up, I discovered this myself. Few audio players know how to get dithering right. It's not all bunk. But reassigning thread priorities certainly is, and so are flac vs wav discussions.don't tell me you've never seen those "Linux sounds better than Windows" or "foobar sounds better than Winamp" discussions...
Not to mention the need for "high-end" SATA harddrive cables....
There has always been a lot of BS among audiophiles, and when they move up to computer audio the BS comes along.

Indeed. Was going to mention USB cables, but your example of hard drive cables is even better. And I guess you need a few resonant crystals on top of your amp box too... 🙂
Well... there are things we dont need to worry about, and this is one of those. And that list of things is VERY long....
But power amplifier quality is something to worry about. At least I did worry until now, the Ncore has cured my upgrade-disease for a long time I think. 🙂

SRC by dropping samples? Whoever coded that got dropped on his head.
