Estimated Year: 2018–Present

Made in: China

Overview

The Mackie HM-4 is a compact 4-way headphone amplifier designed to distribute a single stereo audio signal to multiple listeners. Ideal for home studios, rehearsal spaces, podcast setups, and recording sessions, the HM-4 allows up to four pairs of headphones to monitor the same source while each user controls their own listening level.

The unit features one 1/4" TRS stereo input and four 1/4" headphone outputs with independent volume knobs. This makes it perfect for situations where several musicians or engineers need to hear the same mix during tracking or rehearsal. Its durable steel chassis and simple tabletop design make it easy to integrate into a studio desk or portable recording setup.

Powered by the included 12-volt adapter, the HM-4 offers a straightforward and reliable way to expand headphone monitoring without needing a larger rackmount system. :contentReference[oaicite:1]{index=1}
