NDX not controlling new Pre-amp

Posted by: Dingding on 02 January 2012

I took delivery of a new 252 just before Christmas and seem to be having problems with controlling the pre-amp via the NDX. It all worked perfectly with my old pre-amp and it's still working the NDAC faultlessly. All the controls are on the app but just don't do anything. I have checked the menu on the ndx and it shows that the pre-amp is connected to the remote out and that it's all ok. I have tried disconnecting the dac , swapping the remote outputs,  changing the cables for new ones and shutting the hole system and network down and re-booting it but still nothing.
Thought I would ask if anyone has any ideas or have come across the same problem?
( NDX is running new software )

Thanks in advance and happy new year to all forum members

Hi DingDing -

 

If you are using a 3.5mm-to-RCA cable to connect to your preamp, make sure you are using the left channel.

 

Hope this helps!

 

Hook

 

PS - Congrats on your new 252!

Hi Hook thanks for your reply, Yes I'm using a 3.5mm to RCA left channel cable. I have also tried a RCA to mono 3.5mm. Can't work it out it worked before I think it's got to be the 252.
Thanks again

A few weeks ago, the volume control stopped working on the nServe. I fixed (eventually) by changing inputs. Obviously, you can't do this using the app but try the remote or the front panel.

On a related note, how do you control the pre AND the dac from the NDX? I have a the little wire going from the NDX to the pre. Should I run a second one directly to the dac or daisy chain them? I recently updated the dac software whih scsupposed to mprove NDX/Dac integration, but I guess I need to connect it to the NDX via the remote control socket see any difference?

HI Keith , you will need a 3.5mm to 3.5mm cable to go from your NDX to your NDAC as you have 2 outputs or you can also daisy chain them, eg NDX > NDAC > PREAMP.

Then go into your setup menu on your NDX front panel, System automation, preamp, then enable and all the inputs show up on the app.  You can name them all using the menu on the NDX , the same can be done for the NDAC.

It works rather well plus the volume also shows up on the app too.

Have fun.

Thanks Dingding,

It seems that I need a second 3.5mm-3.5mm lead. I'm off to Maplins as soon as I can!

krm, great if you post how it went. i have same problem w new ndx + new 202. dealer identified 202 as rootcause after checking my cables, setup etc. so will send back for service.

I've had a similar issue too. The nserve and nstream apps worked the volume of my 102, via the NDX, just fine for about a month, and then simply stopped working??!  I spoke with my dealer and they said same thing happened to them. I dont know if the new upgrade helps, as I have not been able to do it yet (I use Mac and the only way to upgrade is via a PC connection

I would love to hear Naim's response to this since it is clearly a common issue.

All working fine for me but I'll flag this thread for Naim tech support.

Thanks Richard! I've tried about every combo of tweaking i know of to fix it and it remains unresponsive.

The last time it stopped working for me I unplugged and reseated the RC5 control wire and it started working again.

 

Has anyone managed to control dimming of the pre lights by remapping the code for one of the inputs to the pre light dimming code? I tried it a while back without success but I may not have had the correct code to dim the lights.

Mine won't work now. I tried plugging the 3.5mm jack into the other (right) output as I intended to use a stereo lead in the left, and it didn't work. So I put it back as it was and won't work. It won't change inputs or control the volume. Arse! As I said in an earlier post, it started working last time when I changed inputs. Sadly, that hasn't worked this time.

AH sorry Keith I feel partly responsible for opening this can of worms.
Posted on: 03 January 2012 by KRM
Don't worry, I've been wanting to try the dac integration ever since I upgraded thso software so this was an accident waiting to happen. I could try the stereo cable (in case the existing one has a dodgy connection) or try it with the dac, but I'll probably call Naim in the morning.

Remote control is back this morning. All I did was change inputs on nServe and the 282 responded. Volume control is back too. It's a rum do!

I need to get hold of your dealer still to find out how he arrived at the 202 being the issue but one thing I can suggest here (that may help the rest of you too) is to try changing the IR output type from "Modulated" to "Demoulated" (or vice versa) in the "System Automation" -> "Advanced" menu. That may get you going...

 

Cheers

I have followed the instructions above but there Is no IR type setting just modulation out Yes/No.
I have tried both ways but neither work.

So is it my new Pre amp or is it the software on the NDX?

I have tried my NDX on another naim Pre-amp and it works fine so my guess is that it has to be the Preamp. But surely Naim haven't changed the control software on there preamps?...

Hi Dingding,

How long did you give it? My system doesn't work at first and takes several minutes/hours to control the amp after I have changed the settings (hence my scare the other evening). I don't know if this is normal but it might be worth leaving your system for a few hours to see if it starts to play the game.

It's teasing me now !!!!!!!!!!

It's been 3 hours and out the blue the volume started working. As I tuned to the wife to show off the new feature then it froze in mute.

It's not a loose cable as the kit is not even in the room and has not been touched. I can still control everything else but not the Pre.

Crazy times.

Very excited Phil - it worked for me!!! Just changed the setting in the advanced menu from "modulated" to "unmodulated" and I got the volume control back on nstream!  THANKS MUCH!  Oh, the little things...that matter!

Ok it's been two weeks or so now so should I return my 252 to naim HQ?.
The app is controling my NDAC and other preamps that I have tried with it.

Thanks for your posting Phil. Tried that setup change, but did not work. I will email you seperately to get your help on this Thanks for great support, Lars

Dear All,

 

I am having the same n-Stream problem with my NDX and new 282. I have tried all the above but still no good. Any further progress on fixing the problem?

 

Thanks

Hi Ast2312,

 

The problems I had were related to the fact that my 282 was old and therefore had a different voltage on the remote input to the newer machines (which meant it worked but was flacky). I now have a newer 252 and (touch wood) haven't had any problems. If your 282 is new you should be fine, in theory. Having said that, the connection is very loose so are you sure that you are getting a good connection? 

 

Is your interconnect stereo or mono? The NDX prefers mono (available at Maplins for not very much) but will cope with stereo if you use the first (left) channel.

Hi KRM,

 

Thanks for the note. All connections seem good and I have checked system automation. My 282 is new but the cable I have used successfully on another 282 (had to get mine replaced).

 

I can only assume its either the n-Stream app, however it does operate all other NDX functions OK (so unlikely to be the app) or poor cable (I have had this cable working ok before) or the NDX is not sending the correct signals to the 282 (dont know too much about this problem).

 

I will keep trying!
