Typepassive
Electronic symbol
100 Watt power attenuator

An attenuator is a passive broadband electronic device that reduces the power of a signal without appreciably distorting its waveform.

An attenuator is effectively the opposite of an amplifier, though the two work by different methods. While an amplifier provides gain, an attenuator provides loss, or gain less than unity. An attenuator is often referred to as a "pad" in audio electronics.[a]
