I was curious as to how much power my Sure TA2024 (pictured below) was using at different volumes, so I used a mains power meter to read the power usage in real time. I would have thought that the amplifier would draw less at low volumes and more at high volumes, but what I saw was a constant 2.5W draw. This doesn't sound right to me.
I'm using a laptop switching PSU rated at 12V 5A. Even turning the volume to 50% makes no difference to the power draw.
What's going on?

An externally hosted image should be here but it was not working when we last tested it.
Because that 2.5W is all quiscent power draw.
Remember that 1W is enough to drive a 88dB/W @ 1m to... er... 88dB, which is what many consider unsafely loud.

That makes sense, thanks. It's amazing how efficient these amplifiers are. So, in theory, a 1 amp adapter should be more than ample.
