When the receiver was asked to produce

more than about 50 watts in four or more channels

with steady-state test signals (sine tones),

it activated its protection modes after about 4

seconds, limiting drive level to a maximum of

about 45 watts. Single-channel performance

was unaffected, but I noted the same protection

operating in full-power stereo tests, though the

limiting interval was longer, nearly 10 seconds.

However, this standard lab-bench measurement

condition is unlikely to be encountered

with real-world music or movie signals.

amp was pushed too hard, went into protection mode.

it is like turning up your gain very high. you pull too much from the amp and it cannot handle it well. the main way that this can be deduced is that it is ASKED for 50, but only pulls 45 so you try and make it get 50 by stressing it. kind of like pulling more than it can make. then, you try and pull that wattage across multiple channels and the problem compounds. this is why it works out of only one channel, because it isn't stressed that hard. correct me if i'm incorrect.

if you go to soundandvisionmag.com and type in Onkyo TX-NR901 in the search box in the upper right hand corner, you can find it ( it's the very first link)
