80,000 Actuations (109 years)
Trinity Black is the latest generation of the industry’s first robotically controlled line source. Stunning SPL and clarity can be precisely controlled with variable coverage in both the vertical and horizontal planes, allowing system operators maximum flexibility in making coverage adjustments after the array is flown. Onboard inclinometers and network-based Auto-Array within PK .dynamics software allow each module to recognize its position and angle within the system, improving accuracy and safety. Intelligibility is dramatically improved through directing the systems energy away from reflective surfaces, as system coverage is adjusted to meet the architectural design of the venue.

Horn loaded 12” transducers manage low frequency response. The mid frequency band is supported by 4 x 6.5” midrange transducers affixed to the patented Coherent Midrange Integrator (CMI). Two dual-diaphragm high-frequency transducers, coupled directly to an integrated planar waveguide, significantly reduces distortion across the high frequency band. A 6000 W Class D amplifier maximizes headroom while maintaining crystal clear audio and exceptional output.

The patented CMI Waveguide seamlessly combines mid and high frequencies, coupled with precisely spaced low frequency apertures for smooth and controlled directivity. It allows for variable adjustability from 60°-120° both symmetrically and asymmetrically. Designers can vary the directivity of individual modules within the array to enhance overall system performance.

Flown straight, the directivity is configured remotely using industrial linear actuators with a duty cycle of up to 109 years. Horizontal angles can be set to one of over 30 variable angles allowing for mechanical optimization. Vertical angles are variable with 0.1° accuracy. Finally, a combination of FIR and IIR filters are applied to ensure smooth frequency response in the listening area.
