PK Sound has announced its T8 robotic line source element and T18 intelligent subwoofer, alongside the PK Cell modular touring rack and PK .dynamics control software. Together, these new elements aim to bring PK Sound’s remote and real-time multi-axis robotic coverage control to a wider range of users and applications in the touring and rental, performance installation, theatrical, worship, nightlife and corporate event verticals.
Integrated inclinometers and network-based Auto-Array via .dynamics software enable each T8 module to recognise its position and angle within the system, enhancing the speed, safety and accuracy of any deployment. Robotic control, onboard DSP and network data are routed through the world’s first use of Neutrik’s DR Series of IP65-rated connectors for maximum stability.
A pair of vented 8-inch Tetracoil transducers with custom phase plugs handle the low-frequency response, while a Dual Ring Radiator coaxial compression driver handles mid and high frequencies. This three-way, high-directivity design offers detailed and variable pattern control of frequencies from 20kHz down to 400Hz, resulting in significant SPL reductions between on-axis and off-axis coverage points. A two-channel VE15 1.4kW class-D amplifier offers high headroom and exceptional output.
The elongated waveguide of the T8 is robotically manipulated to offer variable symmetric and asymmetric horizontal dispersion in 49 configurations, from 60° to 120°, so users can shape an array’s radial directivity remotely and in real time. This enables the configuration of tapered arrays, precisely tailored to meet the unique coverage requirements of any venue or event. Users can focus energy on the audience and away from reflective surfaces or obstacles in indoor venues for maximum intelligibility, in addition to mitigating noise impact on on-site points-of-sale or surrounding commercial and residential areas in outdoor applications.
Flown straight, the array’s directivity is then configured remotely using industrial linear actuators. Vertical angles are variable with 0.1° accuracy, and an entire system can easily be configured and flown by a single operator. A combination of FIR and IIR filters is applied to ensure smooth frequency response throughout the listening area.
The high-output, low-profile T18 subwoofer delivers a peak SPL of 140.4dB and an operating range of 25-100Hz. Sharing many internal components with PK Sound’s flagship T218 subwoofer, T18 features a front-loaded, long-excursion 18-inch transducer in a bass reflex design for clean and punchy output. A large, unrestricted vent enables high SPL performance with minimal port distortion.
A single, field-replaceable module located on the rear of the cabinet contains the 2.7kW class-D amplifier, control electronics and power supply. DSP and Milan-ready networking simplify set-up and calibration, while optimising acoustic performance even for advanced deployments including cardioid configurations and arc delays.
