This is a personal mixer for the PreSonus range, best way to get information is on the PreSonus website by checking out the PreSonus EarMix 16M Personal Monitor.

Designed to work seamlessly with PreSonus' StudioLive Series III family of mixers, yet compatible with other AVB-enabled systems, the PreSonus EarMix™ 16M personal monitor mixer accepts 16 mono channels of input via AVB networking. An aux input admits an external source to the local mix. You get stereo channel linking and channel grouping, along with three-band EQ and limiting for each channel and the main mix, balanced ¼-inch TRS L/R outputs, and a loud, clear headphone amplifier that can drive low impedance devices such as high quality in-ear-monitors. Two AVB jacks enable daisy chaining; network up to 24 units with a StudioLive Series III mixer. The EarMix 16M can be powered from the included external power supply or over Ethernet (PoE) from a compatible switch.
