MACKIE Headphone amplifier HM-4 4-channel

The Mackie HM-4 is a highly compact four-channel headphone amplifier that distributes a single stereo source to up to four pairs of headphones. The stereo input uses a 6.3 mm (1/4 inch) jack, and each of the four 6.3 mm headphone outputs has its own independent volume control, so every listener can set their level without affecting the others.

It suits studio work as well as shared listening at home, for example when four people want to hear the same audio source at the same time. At 200 g and with a compact footprint, it fits easily on a desk or shelf.

The sturdy metal chassis protects the electronics in everyday use. Power is supplied through the included 12 V mains adapter.
