-
Impedance Matching
Amplifier power output is typically specified at a given impedance, usually 8 ohms or 4 ohms. Loudspeaker impedance varies, and an amplifier’s ability to deliver power consistently across different impedances is crucial. A well-designed amplifier will often double its power output when impedance is halved (e.g., from 8 ohms to 4 ohms). This indicates its ability to maintain control over the loudspeaker across a wider range of frequencies and load conditions, but the reverse may be a sign the amp is not capable of handling the load placed on it.
-
Dynamic Headroom
Power output figures provide a steady-state indication of amplifier performance. Dynamic headroom, however, describes the amplifier’s ability to deliver short bursts of power above its rated output. Music is dynamic, and amplifiers require some extra power to drive the speakers as the sound gets louder. Adequate dynamic headroom is essential for accurately reproducing transient musical peaks and preventing clipping, a form of distortion that occurs when the amplifier is driven beyond its capabilities. Without dynamic headroom, the sound may be compressed.
-
