Remarks[edit]
The above performance data are original data according to data sheet. I have made my own measurements with 1000 Hz sine input signal:
- 350 W at 8 Ohm / channel
480 W into 4 Ohm / channel
The measurements were made with a bifilar and pure resistive 1000 W load resistor up to the clipping limit. The power ratings are valid permanently (as long as there is current). They do not change significantly at other frequencies.
This power amp is obviously capable of far more load as well, as it turned out for me. 'For years the WFA-220 runs with me at 2.66 ohms and that also with relatively long and very high levels and that without any problem!!! That is already very remarkable with this model.
