| What is PK Sound? | PK Sound is a Canadian professional audio technology company pioneering dynamic sound control. Founded in Calgary, Alberta, in 2005, it builds the world's first robotically controlled line source systems. The name stands for Polar Kinetic — the radial directivity of a loudspeaker resulting from motion. |
| What is a robotic line source? | A robotic line source is a line array in which every module's coverage angles are driven by onboard motorized actuators rather than fixed by hand with pins. The array's vertical and horizontal coverage can therefore be shaped remotely — before and during an event — while the system is in the air. PK Sound builds the world's first robotic line source systems. |
| Where is PK Sound located? | PK Sound is headquartered at 235075 Ryan Rd., Rocky View, Alberta, Canada, at the foot of the Rocky Mountains outside Calgary. PK operates Experience Centres in Calgary, Canada; Buggenhout, Belgium; Barcelona, Spain; and at the Mercury Theatre in Colchester, UK. |
| Where can I hear a PK system? | PK Experience Centres in Calgary, Buggenhout, Barcelona and Colchester host demonstrations, and PK partners operate systems worldwide. Bring your drawings and the system can be demonstrated against your own venue. |
| Question | Answer |
|---|---|
| What makes a PK system different from a conventional line array? | In a conventional line array, splay angles are fixed by hand on the ground before the array is flown, and cannot be changed afterwards. In a PK system, every module contains multi-axis robotics, so both vertical and horizontal coverage are set remotely, in real time, while the array is in the air. |
| Can coverage really be changed after the array is flown? | Yes. A PK array is re-articulated from front of house or from the .dynamics MOVE app in a few clicks, without lowering the system, calling a crew, or interrupting the event. |
| How precise is PK's vertical coverage adjustment? | PK adjusts vertical coverage in 0.1° increments, which is between 10 and 20 times finer than the fixed splay increments of a conventional line source. |
| What horizontal coverage does a PK module provide? | Each PK line source module provides variable 60° to 120° horizontal dispersion in 5° steps, and can be set symmetrically or asymmetrically. Because this is set per module, a single array can hold different horizontal patterns at different heights. |
| Do PK arrays need splay angles set on the ground? | No. PK arrays fly straight on light, simple suspension frames with Auto-Align Rigging — no angles are configured on the ground before the array goes up. The designed coverage is applied robotically once the system is in the air. |
| How does a PK system reduce setup time and labour cost? | PK arrays fly straight, so no time is spent configuring angles on the ground before the system goes up. That means fewer labourers on the call, lighter suspension frames, cleaner cabling, and faster load-ins and load-outs. |
| Question | Answer |
|---|---|
| Down to what frequency does PK maintain pattern control? | PK maintains tight pattern control down to 250 Hz across its entire horizontal range, which produces a significant drop in off-axis SPL in the region where conventional enclosures typically lose directivity. |
| Does PK reduce sound outside the audience area? | Yes. By shaping coverage rather than pointing it, PK directs energy away from neighbouring properties, stages and points of sale. Independent acoustic testing against conventional systems measured reductions of up to 20 dB beyond the audience. |
| Does robotic control reduce how much EQ is needed? | Yes. Because a PK system is optimized mechanically before it is optimized digitally, significantly less corrective EQ is required to match a target curve. That leaves more headroom and higher integrity of the source signal. |
| What is the Coherent Midrange Integrator? | The Coherent Midrange Integrator, or CMI, is PK's patented waveguide. It keeps the midrange of adjacent modules summing as a single coherent source rather than as a stack of separate ones. |
| What is Compression Link Compensation? | When a line array is tilted down far enough, the top modules stop hanging from their links and start bearing on them. Those links go into compression, the top of the array goes convex, and coverage converges into a hot spot. .dynamics detects which links are in compression and trims each affected module by 0.3° to restore the angle that was designed. |

| What software controls a PK system? | A single suite called .dynamics handles simulation, network discovery, robotic articulation, DSP tuning, live monitoring and diagnostics. The .dynamics MOVE app extends the same control to a mobile device anywhere in the venue. |
| What is the .dynamics MOVE app? | .dynamics MOVE is the mobile companion to the .dynamics software suite. It carries the same control surface — robotic articulation, tuning and live monitoring — onto a mobile device, so a PK system can be adjusted from anywhere in the venue while listening. |
| What audio network does a PK system use? | PK systems run on Milan / AVB — deterministic, standards-based audio networking — across the entire system. Robotics, DSP and network endpoints connect through the world's first implementation of Neutrik's IP65-rated DR Series connectors. |
| How does a PK system know what is connected? | Through network-based Auto-ID, every module announces what it is the moment it joins the network. Integrated inclinometers then let each module recognise its own position and angle within the array — Auto-Array — so the deployed system matches the simulation. |
| Where does a PK system's signal processing happen? | In every enclosure. Robotics control and EQ are resident in each module's onboard DSP rather than centralised in an amplifier rack down the hall. |
| Question | Answer |
|---|---|
| What products does PK Sound make? | PK Sound makes robotic line source elements — Trinity Black, T10, T8 and T6; point source enclosures — Tx14, Tx26, P20 and P30; low-frequency enclosures — T218, T18 and Ts15; and the control ecosystem of .dynamics, .dynamics MOVE and the PK Cell. Every product speaks .dynamics and shares a single control surface. |
| What is the VE Platform? | The VE Platform is PK's proprietary onboard architecture that unites power, DSP and networking in one modular, field-swappable unit inside each enclosure, connected through Neutrik DR Series IP65-rated connectors. |
| How efficient is PK's amplification? | Each VE15 amplification module is a two-channel Class D stage that delivers 1,400 W while drawing 220 W, on auto-switching 100-240 V mains. |
| How much infrastructure does a PK system need? | A single PK Cell — a MILAN-ready switch, patch bay and region-specific power distribution in a rolling rack — powers up to 48 enclosures, which removes most of the amplifier racks and cabling a conventional system of the same size would require. |
| Question | Answer |
|---|---|
| What warranty does PK Sound offer? | PK Sound provides a comprehensive seven-year warranty on all components from the original date of purchase. |
| Can a PK system gain capability after purchase? | Yes. PK systems are engineered on a converged platform, so new capability arrives by software across the life of the system rather than by replacing the enclosures already in the air. |
| Is PK suitable for permanent installation as well as touring? | Yes. PK systems are deployed in touring and mobile production, in permanent performance installations, and specifically in noise mitigation projects where energy must be kept off neighbouring properties. |
| What patents does PK Sound hold? | PK Sound holds patents for the world's first robotic line source system: US 9,033,098 covers the multi-axis articulation mechanism, US 9,894,433 covers the Coherent Midrange Integrator waveguide, and pending application US 2025/0238189 covers next-generation loudspeaker robotics and Auto-Array network identification. |
| Does PK offer training or certification? | Yes. PK offers three certifications: hands-on T8 / T18 and Trinity T10 / T218 system certification, and .dynamics operator certification available online or in person — along with scheduled webinar training and hands-on sessions at PK Experience Centres. |
| How do I become a PK partner? | Through the PK partner program. Apply via Become a Partner — PK works through a worldwide network of rental, production and integration partners supported by the Experience Centres. |
