I have invested in a Chord Mojo and Poly combo for mobile and headphone listening but understand it can be used as a Roon endpoint. I don’t currently use Roon but thought I might trial it, given the downtime we have at the moment. However, I’m not sure how to connect it to the 272? Is it from the headphone out on Chord Poly and then into one of the 3 analog inputs on the 272?? Thank you.
I dont have a Poly but I do have a Mojo, and before I purchased the NDX2 thats exactly how I connected it to my NAC282. I even have a cable with a (Naim type) locking DIN plug for use at the Pre-amp end.
I used one of the aux ports on the Pre-Amp. Didnt use Roon but did stream Hi-Res Qobuz through my iPad. Worked very well.
The cable came from Flashback Sales. You can find them on the Internet.
I think you mean the headphone out on the Mojo, rather than the Poly. Yes, you can use it into an analogue input on the 272. You’ll need a 3.5mm jack to 5-pin DIN lead (probably best) or jack to 2 x RCA.
If you set the Mojo to line level, the output is a rather high 3Volts, so you might want to dial down the volume level a bit. Certainly it was best to do this using Chord Hugo into a separate Naim preamp.
One other point… This was in conjunction with a Mojo. The DAC in the apple device, itself, doesnt support hi-res as I understand it.
As for potential damage by turning the volume up (in the absence of a Mojo or similar) I’d guess it would depend on how much distortion was in the signal. There might be some potential for speaker damage - though I’m no expert in this matter.
