Hailing from Calgary, Canada, PK Sound became a legend in the electronic and bass music festival scene (Excision, Lost Lands, Bass Canyon) before conquering stadium rock and arena tours. PK Sound's crowning breakthrough is the introduction of **Robotic Multi-Axis Variable Directivity**.

1. The Robotic Directivity Breakthrough

In traditional line arrays, if you need to adjust horizontal coverage or vertical splay angles, the sound crew must lower the entire 3-ton array to the stage, pull pins manually, and re-fly the rig. In the **Trinity Black and T10**, every cabinet contains internal high-torque robotic actuators.

  • Remote Horizontal Directivity (60° to 120° in 5° steps): Adjust the horizontal flare of individual boxes from your FOH laptop via PK .toolkit while the array is in the air.
  • Remote Vertical Splay (0.1° resolution): Physically curve or flatten the array mechanically while listening from the audience plane in real time!
