I just replaced my AVR-2500 with the 3805. The 'MULTI' light is always on and I haven't found a way to get it to turn off. I have nothing connected to the Zone 2 or Zone 3 OUT jacks, zone 2 and zone 3 power is off on the status display and both are selected to source. Selecting multi out to source extinguished the multi light on my 2500. Admittedly this doesn't affect operation, but I can't figure out why the light stays on.
