I am trying (unsuccessfully) to automate the operation of my NAC 282 from my NDX. I’ve emailed Naim support, but, while waiting for a reply, I figured I’d ask the community as I am sure that I must be missing something obvious…
I have connections as follows:
NDX connects to AUX1 on the 282 over DIN.
A 3.5mm jack in the NDX’s ‘remote out 1’ runs to the ‘RC5 in’ on the 282. This is a mono 3.5mm to RCA cable (I’ve tried with a stereo cable as well).
Preamp automation is turned on through the NDX’s ‘System automation’ menu.
The preamp source inputs appear in the Naim app as do the volume controls. The NDX responds when selecting these source inputs, but the 282 doesn’t; neither does the 282 respond when changing the volume through the Naim app.
I’m at a loss as to what’s wrong. I’ve reset settings on the NDX and even tried connecting the NDX to the 282’s CD input; no difference: the 282 stubbornly refuses to respond to remote commands from the Naim app. The rc5 codes [viewed in the NDX’s ‘Advanced setup’ menu] are all set to their default values.
Any advice you could give re. what I’m doing incorrectly would be really welcome. Thanks.
Bart, reading the opening post, it appears so. Only time I’ve come across a similar situation, it was down to the lead - trying a different lead and all worked fine. No idea why…
Thanks both. I thought the cable when the stereo one I initially tried didn’t work (on either left or right channel). Unfortunately the mono one I subsequently bought doesn’t work either. Reassured that I’m not doing anything obviously stupid .
Is your 282 a few years old?
There is a hardware mod required on earlier display PCBs to ensure reliable system automation operation.
I cannot recall exactly when it was implemented, but I can check for you?
Assuming the 282 is the same as my Supernait. The following is the NDX display menu I use. It might be worth checking your settings against it
I have the NDX connected to the Supernait’s CD input, also included is a NAT05 FM tuner
NDX Display - System Automation
Pre-Amp > Enabled
Pre CD > No
FM Radio (Pre-Tuner) > Yes
Pre HDD > Disabled
Pre AV > Disabled
Pre Aux1 > Disabled
Pre Aux2 > Disabled
DAC > No
Streamer Audio > Pre CD
CD Player > No
Advanced Setting > No Entry
It absolutely does sound pre-mod!
The mod consists of a resistor value change (surface mount) & a resistor added to the RC5 opto-isolator IC on the display PCB.
I suspect the Class A in Sheffield or similar competent dealer could do it, or of course back to base.
Mike-B : Thanks for taking the time to reply - appreciate it. That matches one of the settings combinations I tried with no joy. Good to know I wasn’t been dumb.
Neil : Thanks again. That’s definitely going to be the problem. Frustratingly, I only had the 282 serviced back at base mid-Jan. Would have been nice to take control from the app, but I can live with using the remote or hand cranking the volume control (first world problem ).
I was expecting some paperwork listing what had been done, but there wasn’t any in the nice new box that I did get. If it accompanied the shipping docs then the dealer took those.
No problem, I’m a bit obsessive about keeping notes & I’m on the beta test team & you need those setting each time I run a factory reset. So 1 minute to copy/paste & you have it.
Hope you get it sorted.
Mark - while you are waiting for Neil to check out the service details, have you tried ‘remote out 2’ on the NDX just to rule out any issues with ‘remote out 1’. Worth checking if you haven’t done so already.
