  • Page 14 3 - INSTALLATION Start the installation by selecting the directory where the software will be installed. If you do not want to change it, it will be installed in the default directory, click with the mouse on the Browse button, and another window appears in which you pick where you want to install the Software.
  • Page 15 3 - INSTALLATION Now the drivers installation screen will appear. Once the drivers has being installed on your PC, the program will inform you of the status of the installation. Then the next screen will report that the entire installation process has been done correctly. To complete the entire installation process of the software and drivers, the following window information appears, confirming that the process is correct and that we must restart the computer for the changes to be implemented.
  • Page 16 3 - INSTALLATION TIPS: When connecting the processor for the first time, as in all peripherals that use USB, we leave a reasonable time for Windows™ to recognize the device and install the specified drivers. The first time you connect the amplifier DSX into a USB port, Windows will detect and install the device on the PC.

By clicking on the "Link" boxes you can give the same parameters to other channels.

  • Page 33: Output Delay

    4 - EDITING WITH DSX You can adjust Output Gains for example: in order to get the right signal to each of the connected amplifiers, according to their own input sensitivity. And/or to compensate elctrically the diferent ways depending of the sensibility of the transducers in a multi way system, knowing that most of the times High and Mid frequencies needs an acoustical adjustment.
  • Page 34 4 - EDITING WITH DSX You also have the option of Temperature change, through which you can introduce the temperature (in Celsius or Fahrenheit) making the calculation of the speed of sound as accurate as possible. The calculation of the speed of sound (Vs) depending on the temperature is obtained with the following formula: Vs = 20.06 x (273+ºC) being ºC the temperature in Celsius degrees.
  • Page 35 4 - EDITING WITH DSX For that we include the possibility of introducing the distances between elements on each output referring to a vertical plane. With these distances we can add the necessary delay to each channel, and visualize as the elements are lining up.

    4 - EDITING WITH DSX 4.11.- Dynamics configuration. The last section that we find on the Main window is the audio Dynamics, which consists of a block of RMS Dynamics and followed for another block of Peak limiter. Once the signal reaches this point there will be some parameters already applied, has Route selection, Gain, Crossover, Equalization and delay.

    4 - EDITING WITH DSX By clicking on buttons and sliders, you can access the configuration of each Dynamic, showing all the parameters (threshold, compression ratio, knee, Release time, etc.).. In the left chart it shows the dynamic curve that expresses the relationship between the level of input in dBu and output. If you do not want the dynamic active, you can press the button "Bypass"...
  • Page 38 4 - EDITING WITH DSX In the Compressor, the Output signal follows the Input signal if you are below the threshold. Once it exceeds, the output is mitigated depending on the chosen Ratio. In the next graphic there is a 1:2 ratio, which means that once the signal exceeds the threshold for every 2 dB increase in the input we will have 1 dB ...
  • Page 39 4 - EDITING WITH DSX The third time we can configure is the HOLD. This would be the time that elapses between when we are below the Threshold until the Release enters. The adjustment of these parameters is very important and critical for the final sound quality. These speeds depend on the frequency range of the input signal.
  • Page 40 4 - EDITING WITH DSX The graphic of the C.R.I. limiter shows a "normal" limiter of +4 dB compared with the C.R.I. limiters with +4 dB with a knee ± 2, 4, 6 and 8 decibels of action. There you can see that the dynamic control is becoming more progressive and we still have headroom even when the Limiter acts.

  • Page 57: Security

    5 - CONFIGURATION 5.4.- Security On many occasions you should block the access to the controls of the processor, avoiding undesired persons modifying the parameters, especially in fixed installations or when renting equipment and you do not want anyone to change any settings, like limiters for example. We have five security/blocking levels,plus one with password in every DSX model.
  • Page 58 5 - CONFIGURATION Once the password is activated, depending on the security level if we try to access a "blocked zone" the amplifier will ask for the password. If you do not enter it properly you will not be able to change anything. Even if you know the password, the security level will only allows you to change the settings that you was permited by this level.
