UNIKA advises to carefully consider the correct settings for each driver. The RMS Compressor and Peak Limiter can be valuable tools to protect drivers, but will not guarantee that the driver cannot be damaged.

  • Page 21: Access Control And Locking

    DSP Audio Processor 7. Access Control and Locking This unit has three access levels, plus locked mode. It is intended to enable the right amount of control to each type user. The three levels are: ● User (user of the system) The user is the person that makes use of the system that the DSP product drives.
  • Page 22 DSP Audio Processor Note:that there is no functional relation between the software password in the network window of the control software, the PIN control system and the hardware-related access control functionality for the DSP software. Each operates separately. If you enter your Developer password, the Hardware drop-down menu will show additional options that will not be visible in the other modes.
  • Page 23 DSP Audio Processor For each level, there is a dialog screen with privileges that you can set for that level, accessed through the Hardware / Access Rights menu. You set the User Mode privileges that are required to work with the unit as a user, while with Administrator and Developer level access, you can allow progressively more detailed settings and adjustments to be made.
