If you want to test an audio amplifier, here is a compact fan-cooled dummy load that can be used to provide any of the three commonly needed load impedances (4 Ω, 6 Ω or 8 Ω), with power rating varying from 125 W to 250 W. Interestingly, this dummy load can be made using readily available and relativity low-cost parts.

The schematic below shows two dummy loads, built into one enclosure. With a speaker connected, the amplifier will see either a 4.3 or 7.4 ohm load while the attached speaker will receive less than about 1% of the output power. You can check the net load for yourself by following the basic electronics formulas. With a simple setup like this you can test at high …

Re: Dummy load for audio amplifier. As mentioned you want a non reactive dummy load, this is the way it's been done for years, you want to measure the performance of the amp not how a speaker loads the amp. High wattage dummy load resistors are fairly expensive but there happens to be a cheap alternative.
Audio Dummy Load

A nice dummy load. I've been building audio amplifiers for years. And until now I've always used just a bare wirewound resistor with some banana plugs as a test load. Well, no longer! I now have a very nice dummy load: It's a simple thing, really, but I thought others might get some inspiration and/or at least be interested in the sources for ...
