I wondered about that, I guess that switch is ok to use while the unit is powered on 
Anyone that’s using “Instant On” … what do you do?
Thanks
IIRC Steve Sells went through this on one of the New Classic threads, if you have a search around you may find it

Ok thanks, I’ll see if I can find it! 
I think Steve Harris (stevesky) posted about the instant on functionality, so possibly worth searching for both Steves (Mr Sells being 110db) with appropriate other search terms.

I’m trawling through all the posts I can find, lots of explanations of how the two modes work but haven’t seen anything yet about disconnecting from “Instant On”
I did find a post that confirms something else for me, that the source (332 in my case) overrides the setting on the power amps, so if they’re set to “Auto Standby” and the pre is set to “Instant On” then the amps will not go into standby. That’s nice.
This is the post I was referring to above, only post from Steve that I can see regarding standby modes

I can’t remember this specific question coming up, but wouldn’t necessarily remember it as I’m not an NC owner (I have olive amps). It’s possible one of @110db or @stevesky has time to answer during the week, I’ve tagged them here. (Not sure whether this comes under hardware or software.

I think it was in an early review of the Uniti Atom, but I can’t really remember .
When I received my 222/250 and set them up for automation, I just tried it and it appears to work - perhaps @Stevesky or @110dB might confirm next week?

Cheers @Eoink, would be good to get clarification on this, I’ll keep “Auto Standby” on with the radio playing until then, would hate to pull the plug on fully powered boxes thinking they’re in low power standby
I think @robert_h‘s suggestion above is the most likely solution.
I suspect this actually means “don’t surprise the amp by switching it off at the wall. Press the front panel standby button first so it can put itself to standby properly. Then you can switch off at the wall. Doesn’t matter if it’s in “instant on” mode or auto standby mode.”

Ok so it sounds like there could be different behaviour when using system automation and the front panel buttons, system automation just turns off the logo and the buttons put it into full standby … I think 
Edit … although I’ve reread it and it says turn off from the pre (i.e. system automation) or the front panel buttons … my head hurts 
I’ll try phoning Naim support to get a definitive answer on this.
Another issue, got my AV system setup after relocating it and when using AV bypass (Unity Gain) it goes into standby after 20 mins cutting off the front speakers 
Nothing going through the preamp! So it goes into standby automatically. You’ll need to put in on “instant on”.
Yes but I’d like to use auto standby, so this is a bit of an issue for me. Seems like when the input is set to AV and unity gain is set (you have to set it) then auto standby should be disabled automatically, a bit of an oversight really.
2 questions:
- when the NC 250 is on standby, what is the average time for reaching its full potential when it’s fully powered again?
- can I unplug the power cord when the 250 is on standby? Is it safe?
Hi, it’s probably dependent on how long it has been in standby, the few times I’ve had to wake mine I’ve usually left them playing quietly in the background for an hour or so … so nothing remotely scientific
Regarding unplugging, if your 250 is set to auto standby then pulling the plug when it’s in standby is safe. If it’s set to instant on then it’s not so clear, to me at least, from what I highlighted in the first post.

To add to the confusion is instant on only an issue for the power amps? I have changed the switch on my 332 in the beginning and in both situations the amp seem to turn itself off after nbeing left with no input for the amount of time specified. Usually sleep is ok in my wworld, but instant on would have been nice during the first few weeks.
Thanks Mark.

I don’t think so, the highlighted text in my first post is from the 332 manual. If you’ve changed yours to instant on and the amp is still set to the default auto standby then the pre should keep the amp powered up as well.
Spoke to Naim technical support today and got an answer for a couple of things mentioned above.
Regarding the standby switch on the rear of the units, it can be switched from auto standby to instant on while the unit is powered on, however switching from instant on to auto standby requires a power cycle. So that rules out @robert_h’s suggestion earlier 
The issue regarding the AV bypass does sound like an oversight and he will raise it internally. However it may need to be a dealer upgrade thing if they warrant it important enough. It is to me.
On the question about disconnecting from the mains when using instant on, seems like pulling the plug (even though they’re fully powered and the manual says to avoid doing that) is the way to do it, in the order of power amp, pre amp, pre amp power supply, source, source power supply and reverse for reconnecting. So same as the Classic boxes.
In our phone conversation he didn’t sound to be completely sure so I’ve asked for confirmation by email.
It would be nice if we could get a reply like the following for the 300 series as they appear to be different.
I had hoped before reading the manual that the New Classic boxes would work in the same way
