Mackie HM-4 Headphone Preamp


Here's What Mackie Say About the HM-4 Headphone Preamp

Perfect for studios, practice spaces, quiet stages, and more, the HM Series offers everything you need whether it is just splitting a single signal to your band, or more complex headphone distribution.

The ultra-compact HM-4 offers a simple yet effective way to split a single stereo signal out into four pairs of headphones. Perfect for quickly splitting a phones mix in the studio or even crowding around a tablet to watch a movie at home.

Excellent Sound Quality

Premium analog circuitry and design delivers an ultra-low noise floor and high headroom. 


With a heavy-gauge steel chassis, long wear potentiometers and switches, the HM Series is built to last.
