The graph is a representation of the transfer function. Fig 4.4.6.2.2. DLP Transfer Function The values represented on the axes are with reference to a -22dBv saturation level.
  • Page 97 The transfer function without DLP would be x=y which corresponds to the 45º line shown in the graph. The practical result in this situation is that there would be no modification in the dynamic range. The system will not allow any dynamic modification at less than -61dB below saturation level.
  • Page 98 4.4.6.2.3. Configuring the DLP When the DLP button is pressed, the Digital Level Processor window appears (fig. 4.4.6.2.3.A). This window is only intended to select a preprogrammed DLP transfer function. To select a previously set configuration, click on the selection list labeled Description.
  • Page 99 • Transition level : is the separation between the upper and lower regions of the transfer function. This separation is used to apply the attack and release times. • Attack time and Release Time on the upper and lower regions : This four parameters show the attack and release time of the DLP on two separated regions of the transfer function : upper (above the transition level) and lower (below the transition level).
  • Page 100 • A new set of buttons appear on the lower left side of the window. This buttons are used to manage the database. From left to right, their actions are the following : - Go to first record - Go to previous record - Go to next record - Go to last record - Add a new record...
  • Page 101 • The attack and release times can be modified (we are editing the DLP). • A new button labeled Graphic appears. By pressing this button, the Digital Level Processor graphic Editor appears. Each record may be edited searching it with the database buttons and pressing the button for editing current record.
  • Page 102 The transfer function is composed by a maximum of 5 points. The lower point is always at the lower left corner and cannot be changed. The upper point has it x value (input level) also fixed to the maximum value. The other 3 possible points of the transfer function are defined through their coordinates on the table below or directly moving them with the mouse on the layout.

Store audio parameters button In this window, the current CU configuration can be stored to a database, or alternately, to a specific CU preset configuration, the destination is user selectable. If the Commentary Unit label is selected, a preset configuration number (from 0 to 1) must be selected (see fig.

Retrieve audio parameters button With this option, the user can load a previously saved configuration from a preset CU configuration, selecting it by number (see fig. 4.4.6.5.A) or from the database, selecting it by name (see fig. 4.4.6.5.B). fig. 4.4.6.5.A.

To access at this option, the user must select the File option and the Direct Connection sub-option at the menu bar.
  • Page 107 Fig 4.5.1 Direct connection set up screen The first task is the configuration of the computer serial port connection to the CU and the communications parameters to be used. The following parameters can be set: • Port: It is possible to select the serial port of the computer to be used (COM1, COM2, COM3, etc.).
  • Page 108 If you wish to control remotely the CU through a ISDN connection using the data channel of an AEQ Codec, contact with AEQ technical staff, who will supply you of a software version with a data channel of 1200 bps.

Using the DCS Engineering Planning software This software is intended to create and manage the configuration of the network composed by several Commentary Control Units (CCU), Control Modules (CM) and Commentary Units (CU). The difference with the software named DCS Realtime Control is that the managing of this network is made in an off-line mode.
  • Page 110 4.6.1. Menu options When the program starts, a plain window appears (fig. 4.6.1.). This window has a little menu bar with the following options : • File - New : Creates a new blank configuration file. - Open : Open a existing configuration file - Configurations : Used to import, export and delete configuration files.
  • Page 111 4.6.2. Creating a new configuration file When the New sub-option of the File option is selected, a new empty network structure appears. The network is represented by a tree which main node is the Control Computer. So, the new tree only has one component (fig. 4.6.2). Fig.
  • Page 112 • Save as : Saves the current structure with a new name • Close : Close the current structure. Once the new file has been created, there are several task to be performed in order to compose the total network structure. These tasks are described in the following sections.
  • Page 113 4.6.4. Adding and deleting elements in the network structure Once the Structure window is opened, the 3 different types of components (CCU, CM, CU) may be added to the structure. This may be done through the Components tool window. The Components window contents an icon corresponding to each type of element.
  • Page 114 • Select the element and press Del key on the keyboard. A warning message will appear. • Drag and drop the element to the trash box. 4.6.5. Assigning profiles to the elements The DCS Engineering Planning software allows to create any number of elements profiles in order to assign them to the different elements of the structure.
  • Page 115 4.6.5.1. Special Profiles : <NEW> To select this option, double-click on the line <NEW>. When this option is selected, the configuration window corresponding to the type of element will appear. These windows are copies of those used on the DCS Realtime Control but having less elements, So, the components of these windows are a subset of the windows in the DCS Realtime Control.

Commentary Unit Profile window Note that when you are changing parameters in any of this windows, you are not really changing any physical device. These parameters are only intended to be saved on a profile that will be assigned to an element of a structure that, later, could be transferred to an actual network.
