Denon 1909 Auto Setup - Help Please


Distinguished Member

I installed a new Denon AVR-1909 yesterday and ran the auto sound setup.

It completed, and correctly determined the distances, sizes and cut-offs but after the first pass it reported an cautionary error.



L\R : Phase

I simply thought I had one or more of my speakers connected with the wrong polarity.

This morning, using a continuity tester I checked connection between the Amplifier and Speakers binding posts.

Everything checked out - negative connected to negative, positive connected to positive.

I tested the two fronts and the centre.

I haven't checked the two rears yet as I need to rig up an extension wire for my continuity tester so that it will reach.

Any ideas, as I'm perplexed.

1 - Could the Auto-Setup be mistaken?
2 - Could there be an internal wiring error in the Speakers?

What else could I try - if the Auto Setup was indictating one speaker then I would just swap the polarity regardless but it hasn't been so specific.

As it states in the manual, ignore this error once you have checked the wiring is set up correctly
