Looking some help connecting Onkyo TX-RZ50 pre out FRONTS to my Naim NAC 272 with Power amp NAP250.
Have connected with RCA cable to analogue in on the 272 and set volume to fixed, getting sound out of all surround speakers but nothing from fronts!
Check the audio menu on the Onkyo, you may have to enable the pre-out outputs.
@Richard.Dane , as always in these situations, is called.
I would check all three analogue inputs (make sure they are enabled in the menu). Otherwise as Moondrifter advises above, check whether the Onkyo has to have the pre-out enabled.
