Changing cd input for 282

Can you be more specific about how you hooked the CD players up? Such as using DIN or RCA cables and specifically to what inputs on the 282? Do you use any preamp automation from a Naim streamer to control source selection?

My "guess" might be that the NAD is connected via RCA to the RCA CD in on the 282 whereas the CDX is on the DIN input for CD - but only one of these should ever be connected at any one time.

On the assumption that your CDX2 is powering up and seems to be playing a CD OK, I'd echo the above reply and try connecting the CDX2 to the Tuner input... if that doesn't work I'll eat my hat  

CDX2 into the standard Din input, Nad CD player into aux1 (I think). Then select aux1 by using the instructions as given in the CDX2 manual. It's quite acceptable to have both connected at the same time, and even both selected at the same time. Obviously Naim recommend Din for best sound quality.

My problem is that having selected the aux1 input for CD I can't go back to Din even though as far as I can see I'm following the instructions in the  manual. I'll try the tuner input if I can find the appropriate  cable. 

If the NAD has its signal ground connected to its main, then having both it and the CDX2 connected to the system at the same time creates an earth loop and impairs performance.  They will both sound similar and under par.  Best to have only one connected at any time.  No need to to have two CD players connected at the same time.

I'm not sure though why you can't change input.  Is the NAC282 set for auto input switching?

Richard, the Nad is a temporary addition to keep me going while I decide whether at the moment I can afford the expense and hassle of sending the CDX2 back to Naim for repair. I want to minimise the changes to my system which is why I have two cd players connected. According to the manual the configuration I have is perfectly valid but if you reckon it's not I won't pursue this. The Nad works well for the time being. It's  a superb player and for the money is a real bargain.

All I want to do is to switch back to the CDX2 as shown on page E11 of the CDX2 manual but I can't get it to work. Works fine for the Nad and that's what I'm listening to at the moment but I can't get back to the CDX2. Should be simple if the manual is correct.

Yup, if the NAD is connected to AUX RCA and the CDX to CD DIN that should be perfectly find. It is just 2 different sources on two different inputs that happen to both be CD players. The 282 doesn't know the difference.

• So can you do something very basic? Press each input button from right to left sequentially and not the behavior. Does the input light change on each press and follow the selection?
• If not, can you power the 282 down (power amp first please, and including the NAPSC), wait 60 seconds, then power it up with no input cables connected and do the same test? What are the results?

If you can confirm selection works for each input after a power cycle and with nothing connected, then start re-connecting the sources paying careful attention that the CDX really goes to CD in DIN and the NAD really goes to AUX in RCA. Of course, if the behavior is funky even with no sources connected, maybe fire off an email to Naim support.

Have you cheked  in the Owners Manual for Preamps 10.2 Input Socket Assignment?

Erich,

Yes I'm doing everything by the manual. That's why I'm so puzzled it doesn't seem to do what I want to do.

I'll probably power the CDX2 down and reboot it and check what happens then I'll just get back to listening to the Nad. I'll worry about it again when I can afford to have the CDX2 repaired.

Cheers.

Yes I agree with the above..CD and AUX1 can either be assigned as Phono or DIN... but clearly not both at the same time. (Again read manual on changing and resetting this)

Also as Richard says, it is best to only have one CD connected to the 282 ( it doesn't have to be selected). If the NAD CD also has an mains earthed ground as the Naim CD players do you will have created a SQ robbing earth loop.

You could always unplug the NAD and plug the CDX2 into that socket on the 282 just to check whether you have fixed the CDX2.

The CDX2 is a very nice player and if you can't be bothered or can't afford to repair it, it will still have significant second hand value, although the way to maximise your return would be to repair it and then sell it.
