Double Dynamics (RMS and Peak) are standard in all ARK-71 models. These double dynamics lowerlevels of distortion and provide protection for all the speaker components and internal electronics.
ARK software has been designed for fast user access to make each processing zone simpler for the user. The Compare function option enables the user to listen to the difference between 2 complete set ups in real time with no fade-ins or fade-outs.
As well as being able to import measurement curves from the principal systems (SMAART LIVE, CLIO, SAT Live etc), they can also be seen directly in the final frequency response window showing the effects ofthe process applied. All ARK processors can be configured and monitored in real time by USB or Ethernet.
