The Mackie HM-4 is a 4-way headphone amplifier designed to provide simple and effective headphone amplification for artists, musicians, and engineers monitoring through headphones in home, project, commercial, and mobile-recording studios. Its single 1/4" TRS stereo input and four 1/4" TRS stereo outputs allow you to distribute a stereo source to up to four pairs of headphones.
Each output is controlled via a dedicated level knob, allowing varied listening volumes for each person. The compact heavy-gauge steel chassis offers rugged durability and a convenient power status indicator on its front panel. Use the included 12 VDC power supply to power the HM-4.
