  • Page 19: Setting The Unit Name

    ENTER Before your PC can take control of the iDR-4 you need to set up its unit name and communication settings. This is done using a simple front panel menu system. Once communication is established between the PC and iDR-4 you use the iDR System Manager software to configure the DSP resources and parameters.

  • Page 20: Getting Started - Checking The Hardware

    Getting Started – Checking the Hardware The iDR-4 is supplied with its settings pre-configured so that you can turn it on and immediately get audio passing through it. This can be useful when you are installing a unit on site and need to carry out initial tests on the hardware before the custom configuration software is loaded.

    It is also possible that the PC you use to configure iDR-4 the iDR-4 is also used with a network at your place of work. If it AUDIO MIX PROCESSOR is served by a DHCP server then it is likely that it does not have its own permanent IP address as this is leased by the server.

    DHCP should be turned off (see below). If an address change is needed, consider whether you want to change it on the iDR-4 unit or your PC. To make this decision you may need to consult with the network administrator if the unit or the PC is also used with a network, or the site engineer if other PCs are to be used with the unit.

Note the connection of DR-Link which is daisy chained from one unit to the next. If an iDR-switch unit is also fitted then daisy chain DR-LINK DR-Link from the last expander to the switch box.

  • Page 32: Linking Idr-4 Units

    Linking iDR Units Several iDR-4 and iDR-8 units can be daisy chained together such that audio is passed between them using the 8 channel expander bus. An iDR-in expander can be added to the first unit in the chain, and an iDR-out expander can be added to the last unit.

You need to select two of the three options using the iDR System Manager software Communications Option window.

  • Page 38: The Idr-4 Memory System

    The iDR-4 Memory System The iDR-4 has onboard flash memory. This is non-volatile memory that retains its settings when power is removed. Although the unit is configured using a PC, it holds its own operating code and settings in this memory for stand alone operation once the PC is removed.

  • Page 39: Starting With Patches

    The patch system is the key to the iDR system’s unique flexibility. Unlike some systems which simply take a ‘snapshot’ of all the current settings, the iDR-4 can store and recall any number of chosen settings from an extensive list of parameters.
