HM-4

Mackie HM-4: headphone amplifier for podcasting, home recording.

The Mackie HM-4 is a headphone amplifier used to distribute or amplify monitoring. The number of headphone sockets does not automatically mean the same number of independent mixes. SONORYN checks the source feeding the unit, the connection and the monitoring requirement separately.

THE IDEA IN A FEW WORDS

Where the Mackie HM-4 fits in a creator setup.

What it brings

Headphone outputs: 4.
Headphone connector: 6.35 mm TRS.
Headphone Output Impedance Ohm: 47 Ω.

A good fit if…

Fits your setup.

Several listeners need the same monitored program and the source feeding the amplifier is defined.
You have counted actual headphone outputs and adapters.
You understand the difference between independent volume and independent mixes.

Consider another option if…

Do not overbuy.

Each listener needs a different mix rather than only individual volume.
There is no defined source output available to feed the amplifier.
You are expecting the number of sockets alone to prove level capability.

What you need

Complete the chain.

A defined source output and compatible input cable.
One output path per listener.
Power and load requirements checked for the actual headphones.

First steps

Identify the exact model and the devices it will connect to.
