SLOA105 4 Calculating Gain for Audio Amplifiers 2.3 SE Example Questions: An engineer’s design requires 100 mW of RMS output power to be driven into his 16-Ω speaker. The audio amplifier runs off a 5-V supply and is driven by an audio CODEC that has a maximum
How Much Amplifier Power | Crown Audio - Professional ...
https://www.crownaudio.com/how-much-amplifier-power
If you are playing light dance music, the amplifier's 4-ohm power should be 1.6 x 100 W or 160 W continuous per channel. To handle heavy metal/grunge, the amplifier's 4-ohm power should be 2.5 x 100 W or 250 W continuous per channel. If you use much more power, you are likely to damage the speaker by forcing the speaker cone to its limits.

Where: APR = amplifier required power L P = required SPL at listener H = desired amplifier headroom L S = loudspeaker sensitivity at 1 watt and 1 meter D 2 = distance to farthest listener D R = 1 meter or 3.28 feet reference distance

20/4R = 5 Amperes of current into the speaker. 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.

Extron Audio Calculators. Extron provides a series of audio calculators that sound system designers, engineers, and technicians frequently need to access, such as determining amplifier power requirements, converting between dBu and dBV or volts, or estimating the loss in sound pressure level with an increase in distance.
What is the Power Consumption of my amplifier? – MESA ...
https://mesaboogie.zendesk.com/hc/en-us/articles/115003818313-What-is-the-Power-Consumption-of-my-amplifier-
How to determine the power consumption of your amplifier. The most power that any amp will ever draw is the AC line voltage multiplied by the amplifier's fuse value and even then, it is unlikely to ever reach its maximum level. For example, in the case of a domestic model Bass Strategy Eight:88 this calculates as 10A x 120V = 1200W. Since much of the power is dissipated …
