  • Page 2: Important Warning

    Never try auto-maintenance or repairs on any machine without the written authorisation of IDT Sound Processing Corporation or a maintenance expert mandated by the company (a list can be supplied by IDT Sound Processing Corporation). Should these conditions not be respected IDT Sound Processing Corporation shall suspend all guarantees.
  • Page 3: Something To Read Before Setting Up

    IDT Sound Processing Corporation has loaned you a processor. This loan is not invoiced but care must, naturally, be taken to make sure that it is returned to IDT Sound Processing Corporation in exactly the same condition it was delivered to you.
  • Page 4: Maintenance Of Your Processor

    Should your processor have been exposed to fluids, smoke or dust it must be thoroughly cleaned. However, your processor should not be opened unless you have the authorization from a technician from IDT Sound Processing Corporation without which your guarantee can be cancelled. Call IDT Sound Processing Corporation in any such case.

  • Page 19: Local Switches/Gpio

    Local Switches/GPIO The "Local Switches & Alarms" is aimed at switching presets by local switch and the feeding of the LEDs. On the DEP the connector is a SUB D 25 points. The DEP allows the switching between presets. This is done by the grounding of one of the 8 pins of the connector.
  • Page 20 When you have placed your cursor on one of the pins of the connector it will change colour to show which pin has been selected. . When you click it you will access the various programmable functions of the connector. In the example below we will set pin 1 of the connector to switch a preset.
  • Page 21 The next window shows that pin n°1 of the connector is programmed to switch to the preset Mid + APC + HF Opt. In the same way you can programme outgoing information or alarms. In the example below we have programmed the pin n° 14 of the connector an alarm will be set off if the TX1 Level goes over 75 kHz.
  • Page 22 The window below indicates the programmation of the pin n° 14 that we have just done as well as other programmations. When a command is effective or an alarm has been set off this will be indicated by a red LED on the connector. In the example above an alarm shows that the modulation of the TX2 is under that fixed by the TX2 programmation.
