Bose Professional DeltaQ™ technology defines the next-generation in loudspeaker array design with selectable coverage patterns that more precisely direct sound to audience areas for the best possible sound quality and vocal clarity throughout the listening area.
- DeltaQ™ Arrays improve sound quality and vocal clarity by allowing directivity, or “Q,” to vary with each array module, directing more sound to the audience and less to walls and floors.
- Choice of Horizontal Coverage. Array modules are available with up to 4 different horizontal patterns to reduce unwanted wall reflections and increase projection to back-row seats.
- Choice of Vertical Coverage. Array modules are available with up to 5 different vertical patterns to allow large coverage angles with fewer modules and help equalize front-to-back sound levels.
- Focused Coverage Over Wide Frequency Range. The choice of both horizontal and vertical patterns allows total array coverage to more precisely match the size and shape of audience areas. The result is more consistent coverage over a wide frequency range as compared to that of conventional line arrays. Better sound quality from side-to-side and front-to-back throughout the audience area with higher direct-sound rations to minimize the impact of bad room acoustics.
- Outstanding Vocal Clarity and Midrange Projection. Guiding principles of DeltaQ™ technology include largest-in-class waveguides to control coverage patterns to lower frequencies and proprietary compression drivers that eliminate crossover points in the critical 1-4 kHz vocal clarity range. The result is increased midrange projection and outstanding vocal clarity.
- Get the array coverage you need with fewer boxes. Choice of different vertical coverage patterns gives designers the flexibility to choose the number of boxes in arrays based on output level, coverage control, and budgets -- without sacrificing coverage. Conventional line arrays can require up to twice the box count compared to DeltaQ™ arrays to achieve comparable vertical coverage. DeltaQ™ arrays can improve sight lines, reduce rigging weight, and lower system costs.
