headphone amp(redirected from Headphone amplifier)
Also found in: Wikipedia.
headphone amp(1) A device that drives multiple headphones from a mixing console for studio recording.
(2) An amplifier designed to output the required wattage for headphones. The sound in low-end headphones can be improved; however, music lovers claim that a headphone amp is essential when high-quality headphones are used. Headphone amps can be analog only, boosting the stereo signal from any preamp output or from the headphone jack of a music player. However, they are often combined with a DAC and accept digital audio from computers, providing support for higher resolutions than the built-in sound card (see DAC/headphone amp and USB DAC).
