Heat losses are the thermal emissions from an amplifier while it is operating. It comes from dissipated waste power—i.e., real AC power in minus audio power out. Measurements are provided for various loads at idle, 1/8 of average full power, 1/3 of average full power, and full power, with all channels driven simultaneously.
Amplifiers: Amplifier Power - Lenard Audio

20V x 5A = 100 Watts. The 5A is supplied from the 30V supply (through the transistor) to the 4R speaker. 5A x 30V = 150W. 50W heat is dissipated by the transistor into the heat sink. Therefore at full power the amplifier is approx 65% to 70% efficient. 70% efficient Class B solid state amplifiers are described as being 70% efficient at full power. In academic text, the …

amplifier model and "nr" means the model is not rated for the particular load. This data is measured from representative samples; due to production tolerances, actual heat emissions may vary slightly from one unit to another. Bridged mono into 8 ohms is equivalent to 4 ohms per channel; into 4 ohms is equivalent to 2 ohms per channel.

Heatsinks And Amplifiers
https://sound-au.com/articles/heatsink-amp.htm
When an amplifier is driven with a sinewave to just below clipping, a suitably pessimistic assumption is that transistor dissipation (two devices in push-pull) is roughly 50% (both devices) of the power delivered to the load. The worst case is to run the amplifier at half output voltage (one quarter of full power), when the total transistor dissipation will be close to double the …

speakers have a low impedance, typically 8-Ohm. Even for a low-power 0.5W audio amplifier, PIR 2 /2 requires that the amplifier must be able to source a peak AC current of around 350 mA with an 8-Ohm load. This is a lot more than a typical op-amp is designed to provide. For example, the LM358 and LF353 (two op-amps used in this lab) can source

Audio Connections. Connect the amplifier outputs to the Load terminals on the Active LoadBox. Be sure to use a short length of heavy guage speaker wire so that wire resistance does not impace the results, This is especially important when testing with a 1 O load. Connect the Signal jacks on the Loadbox to the analog inputs on the analyzer. Usage

16777. 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.

DIY Audio Home. A nice dummy load. ... series with two in parallel). Really, the only reason for the 12 ohm load is that I use this to measure Zout of an amplifier, by measuring the output voltage difference form 8 to 12 ohms. The switch is a little odd... it is a DPDT switch but has three positions. ... (it would probably take an hour to heat ...
