252 Selecting Wrong Channel

[What_Are_You_To_Me]

Hi there, I’m sure I’m going to kick myself when I work out what the root cause is, but for the life of me I cannot work it out…

Basically, I was previously using Aux 2 to play music through my 252 using RCA cables. I now use a DIN cable via the CD input. Despite having re-programmed Aux 2 back to DIN from RCA, whenever I play music (either via Roon or the Naim app), the 252 switches to Aux 2 rather than CD. Any ideas on what I’m doing wrong as it’s very frustrating?

NDX 2 to Nap 252 System Automation enigma

Hey everyone. Got my new NDX 2 today. Coming from Unity Star Universe I immediately connected an 3.5 jack from the NDX 2 to the Nap 252’s RC5 in to control the volume of the Nac 252 from the app. The NDX 2 is connected to the HDD din input of my Nac 252. In the Naim app, each time I select a new album to listen to and tap play, the Nac 252 jumps to the cd input and no sound, unless I use the remote to switch back to the HDD input source. If someone in the community can put me on the right pat…

Perfect, thank you very much. The fix was under system automation settings - the preamp was routed to channel 6. Simple change to #1 and it now works.

Thanks again, I would never have thought to look there
