DAX-202 USER MANUAL Introduction Hearing impaired audio has traditionally been generated by the cinema processor as a mix of the left, center, and right audio channels. With digital cinema, it is possible to include a separate hearing impaired (HI) and visual narration (VI-N) track in the digital cinema package. Most digital cinema servers place the HI/VI-N pair on AES channels 7/8 or AES channels 15/16.
Setup 1. Using the chart below, determine where the HI/VI-N AES sources will come from. Source DB25 pins Dolby 7/8 6 / 19 DCI 7/8 7 / 20 DCI 15/16 1 / 14 DCI 9/10 18 / 6 DCI 13/14 15 / 3 — BNC 2. Remove the four cover screws holding the DAX box together. 3. Close the PAIR of DIP switches that correspond to your source selection. See Figure 3. 4. Replace the cover screws. 5. Connect the HI output of the cinema processor to the HI input on the Phoenix connector.
to the Gnd pin. 7. The HI signal can be sourced from either the cinema processor or the cinema server. With no connection to the HI CTL (Pin 9 Phoenix Connector), the HI source will be the cinema processor. If HI CTL is grounded, the source will be the cinema server. The cinema automation system can also be used to select HI sources. Connect and Test 8. Plug in the Phoenix connector, BNC, DB25 input and output as needed. 9. Plug in the power supply into the DAX and into the line. 10.
