Just quick fyi- I took delivery of my Mallard M27 yesterday. Everything was demo'd well. I guess due to the other noises in the area i never noticed how my speakers were wired. Zone 1 had one speaker indoors and 1 speaker outdoors. Zone 2 was the same. I assume this was just wired incorrectly and corrected the issue myself ensuring zone 1 and zone 2 were inside \outside with right and left speakers in each zone. Glad I noticed before we sent camping and disturbed the neighbors.
