Presonus HP4

Tired of straining to hear your headphones? The Presonus HP4's four 130 mW headphone outputs are clear, clean, and screaming loud, all packed in a compact, 1/3 RU chassis. The Presonus HP4 includes balanced L/R line inputs and outputs, global mute, overall level control, and sum to mono. Versatile enough so that your line outputs can feed another external input.
