It takes AES3 digital audio and converts a 5.1 program to analog for the amplifier rack, with routing for Hearing Impaired (HI) and Visually Impaired Narration (VI-N) channels. It is a compact rack unit, 19 inches wide and 1.75 inches high.\u003c\/p\u003e\n\n\u003ch2\u003eHow does the Dolby CAT 1796 work?\u003c\/h2\u003e\n\u003cp\u003eDigital audio arrives on a 4xAES DB25-female connector that follows the DMA8Plus\/CP750\/CP850 pinout, or on RJ45 inputs for channels 1-8 and 15\/16. The RJ45 and DB25 AES inputs are wired in parallel, so one connector is used and the other is left unconnected. Eight channels are accepted, with channels 7\/8 or 15\/16 selectable for HI\/VI-N.\u003c\/p\u003e\n\u003cp\u003eHI and VI-N can leave the unit digitally, on pair 4 of a single RJ45 that matches the pinout of Sony transmitters, Odyssey HI\/VI-N RJ breakout boards and others, or as balanced analog on a 5-position, 3.81 mm Phoenix plug. Jumpers select the AES channels used for HI\/VI and whether that output is digital or analog.\u003c\/p\u003e\n\u003cp\u003eInternal jumpers set the unit for 5.1 plus HI\/VI-N (the default) or Dolby Surround 7.1. In a 7.1 installation, HI\/VI-N must be routed outside this device.
