The Mackie HM-4 is the ultimate, no-nonsense solution for expanding your studio’s monitoring capacity without breaking the bank. Most entry-to-mid-tier audio interfaces only provide one or two headphone jacks; this ultra-compact desktop unit solves that bottleneck by cleanly splitting a single stereo signal into four separate outputs.

For composers and producers tracking live musicians, vocalists, or collaborating side-by-side in the studio, the HM-4 is a workflow lifesaver. Each of the four outputs features its own dedicated level control, allowing everyone in the room to customize their own listening volume without impacting the main mix.

True to Mackie’s legendary "Built-Like-A-Tank™" philosophy, the heavy-gauge steel chassis and long-wear potentiometers are engineered to handle the daily rigors of studio life. Despite its incredibly budget-friendly price point, its premium analog circuitry ensures maximum headroom and a remarkably low noise floor, ensuring your cue mixes remain crystal clear and distortion-free.
