[QUOTE="Ivan Beaver, post: 141236, member: 30"] Re: Calculating Consumption in Watts, Total System Draw Where did you get the power consumption (1/8th watt) for the amps? I did not look to find out-sorry. If it is just the "calculated power", then that would be wrong. All electronics have idle current, that will add power consumption to the actual power output. Also amps are not 100% efficient, so they pull more than they put out. Also-just because the amps are not clipping does not mean they are not delivering more than you think With some styles of music, it is quite possible to be close to full output power and still not clip the amp. It depends on they dynamic range/crest factor of the music. A sine wave draws and delivers quite a bit of power with a very small crest factor (3dB). [/QUOTE]
