What is the model of the digital crossover used in ISP's FOH systems?

The digital crossover used in ISP's Front of House (FOH) systems is the DBX DriveRack 360. This choice is correct due to the specific features and capabilities that the DriveRack 360 offers for live sound reinforcement.

The DriveRack 360 is designed to manage and optimize signal processing in professional audio setups. It includes advanced features such as automatic feedback suppression, which helps maintain sound quality during performances, and a variety of processing options that are tailored for different types of loudspeakers and performance environments. Its versatility allows sound engineers to effectively manage the crossover points for different frequency ranges, which is crucial for ensuring that speakers handle audio frequencies appropriately without distortion.

While the other options may provide some form of mixing or processing capabilities, they do not offer the comprehensive crossover functionality and specialized features that make the DriveRack 360 particularly suitable for FOH applications in live sound environments. The Behringer DSP 112 is more of a basic signal processor, the Yamaha MG32 is primarily a mixer with limited crossover features, and the Mackie Onyx 1640 focuses on mixing rather than dedicated crossover processing. Hence, the DBX DriveRack 360 stands out as the most practical and effective choice for a high-performance digital crossover in FOH
