The IED1544AIO-D is a 4-input x 4-output mic / line level analog pre-amplifier that converts analog audio signals to Dante network audio. Multiple channels of Dante network audio can be transported over standard IP networks. The IED1544AIO-D 4x4 Dante I/O Module features four analog balanced mic or line inputs (selectable) and four balanced line outputs. The four analog inputs are converted into Dante network audio and can be routed via Dante Controller™. The four outputs convert Dante digital audio received over the LAN into analog audio. There are indicators for network connection, network audio traffic, and power. Each input can be selected to Line or Mic level. In Mic mode, each input has 3 gain selections with Phantom Power. The IED1544AIO-D requires no external power supply. It is powered via a network PoE port or a PoE injector.
