*Power-Sharing: On 125W models only, each channel pair has a power
supply which cannot exceed 250W. Either channel can deliver 250W if
the supply allows. For example, you can pull out 250W from CH1 if you
don't use CH2. Similarly, you could pull 50W from CH1 and 200W from
CH2, or 125W from both channels. In any combination, the maximum
power for each channel pair is 250W.
