Oz Audio HM6 QMix Headphone Amplifier and Mixer

Six headphone output channels and lots of input and mixing capability. It starts with a stereo main input and adds 4 auxiliary inputs, an effects send, and stereo effect return. Each channel has level control over the main volume, all 4 aux inputs, and the stereo effects return. It offers clean audio performance through the use of balanced connections throughout, sealed controls that keep dirt and grime from making pots sound scratchy, as well as super heavy-duty construction. The HM6 provides enough gain to push 60 ohm headphones to 128dB into each ear.
