The DGX-AIE is an audio insert / extract board for the Enova DGX 8, 16, 32 and Enova DGX 64. The board provides insert or extract access to the first 16 video input or output positions. The Enova DGX 8, 16 and Enova DGX 32 enclosures both support one audio insert/extract board on the input side and one on the output side. The Enova DGX 64 supports 4 audio insert / extract boards on the input side and four on the output side. The audio insert/extract board simplifies system design by allowing audio from a source located near the Enova DGX to be plugged directly into the system. This can dramatically reduce the overall cost of the system by eliminating the need for additional Transmitters or Receivers. Extract embedded audio and send to a separate audio system to be distributed throughout an environment.
