Definition
A radio or audio system specification indicating the maximum audio output level (typically measured in milliwatts or volts) that the equipment is permitted to deliver to a connected speaker without exceeding design or certification limits.
Plain English
The most audio power the radio is rated to send to its speaker. Pushing beyond this level can distort the sound or damage the speaker.
Context Anchor
Seen in descriptions of aircraft radios, intercoms, and audio control panels that explain which sounds the pilot can hear.
Why Pilots Care
Maintains focus by restricting non-essential audio that could distract during critical flight phases.
Intuition Check
“Allowed” does not mean air traffic control gave permission. Here it means the audio system is letting the sound pass through to the speaker.
Example Sentence 1
The installation manual lists the maximum power allowed to come from the speaker as 5 watts, so the technician selected a speaker rated above that figure.
Example Sentence 2
After landing the crew permitted the ground controller's taxi instructions to come from the speaker.
