Hi
I have just purchased a headline2 and don’t know which input to use. It says plug 4 on my hi cap but that is already in use for my nac 282. Help!
A Headline requires a Power Supply. Such as a HiCap (or FlatCap or iSupply).
But… a HiCap can only power one item… such as an NAC282.

Can your power amp power your 282? That would free up your HiCap for the Headline during headphone sessions. If not - you’ll require a separate PSU for the Headline.

I have read the Naim tutorial on the headline but the 5 pin din lead I have supplied with it has nowhere in my system to go. I have an ndx2 nac 282, napsc,nap 250dr and hi cap. Any suggestions
250 means you need that extra power supply - sorry. I would have hoped that the seller of the Headline would have mentioned that.

There are two connections on the Headline Power and Signal. The captive cable terminated in a 180deg DIN5 plug takes the audio signal from the pre-amp. This can connect to any of the DIN5 outputs on the 282 (Tape in/out , Av in / out , Aux 1 in / out)
You also need a power cable to connect the Headline to an appropriate Naim PSU. A flatcap / Hicap etc would need a SLIC cable (2 pin plug to 240deg DIN5 plug).

(Of course - I’d forgotten that I had to buy a SLIC as well as a separate item).
I’ve never used a 282 - I don’t suppose the aux2 would power the Headline - as the 552 can - ? (and for best sound quality removing that connection when not in use).
From a power perspective, it supplies 24v on the right 240deg socket, but as you’re connecting the signal too, you’ll end with a ground loop and degraded performance.
On a 552 (and 252), you have the Aux2 socket taking dedicated rails straight from the 552PS / Supercap (via the Burndy). With the 282 you’d be sharing other power rails internal to the pre-amp.

OK - as I say I have no idea about 282 - but I can confirm that powering Headline from 552 sounds better than a dedicated HiCap DR. I just disconnect again when going back to speakers.

Another option for powering a Headline is to buy a second NAPSC, which comes with a built-in secondary power cable with the two pin screw connector (effectively a SLIC, as mentioned above), just like on your 282.
(Note: you cannot “borrow” the existing NAPSC from the 282 - the 282 will not work without it).
Obviously a NAPSC (in either olive or Classic case) will be cheaper than a Hicap. and will still sound pretty reasonable.

Flatcaps and Supercaps at either end of the price scales are additional alternatives. Flatcap gets a VFM vote from me, but confess I haven’t compared to NAPSC which is a very popular otion.

Does that mean another hi cap needed?
Yes, or one of the other power supply options that have been mentioned on the thread.
AIUI, you have a NAC282 and a NAP250. As the 250 does not incorporate a “preamp power supply”, you are using your existing Hicap and NAPSC to power the 282; both are required for that purpose.
You have acquired a Headline. The Headline requires its own dedicated PSU. This PSU can be a iSupply, NAPSC, Flatcap, Hicap or Supercap. Only the NAPSC has an integral secondary power lead suitable for the Headline; all the others will need an adaptor of some sort.
The 282’s Aux2 socket does indeed provide a secondary supply output, but that is intended for a Stageline or Superline phono stage, and probably not recommended for use powering a Headline.
As I said above, your cheapest option is a NAPSC. It’s OK, even “pretty darn good” 
.
(FWIW, I have both a Headline (olive) and a Headline 2 (black case). I have run them both from NAPSC (olive) and NAPSC 2 (black case) . I currently run my Headline 2 from an olive Hicap - because (a) I had a spare Hicap, and (b) it has an on/off switch! 
)
I still don’t understand. I need an input for a 5 pin din slic lead from my Headline
Try
Connect the signal input to one of the spare outputs on your 282
Connect the headline power socket input to a suitable supply. You may need a SLIC cable here depending on the PSU you have.
You’ll need a power supply for the Headline; either an i-Supply (H), NAPSC, Flatcap, HICAP, or Supercap.
Only the Flatcap, HICAP, or Supercap need the SLIC lead, the i-Supply (H), and NAPSC have the necessary captive leads (and adaptor in the case of the i-Supply (H)).
