Summary: This was my 1st ONKYO brand. In the warranty period I had numerous failures with HDMI issues but each time was walked through ways to attempt fixes. Had TERRIBLE luck with customer service but LOVED that they were USA based and spoke perfect English (SHOCK!). By the time I got to the point this device would no longer even limp along with constant "tweaking" and I could no longer get picture using HDMI cables (ANY brand, ANY price!), I gave up.
Summary: Zone B does not work with digital input. We can only listen to the radio tuner on our 'patio zone'. I think they over engineered it by making the zones discreet. If I want to crank the tunes outside, I am used to just pressint the B button. This unit requires you to also chose the input source for the zone.
