Solton KARAT K4 A is an active, bi-amped two-way line array element built for demanding touring applications indoors and outdoors, with a design focus on exceptional vocal intelligibility in difficult acoustic environments. Four 5-inch neodymium woofers and two high-quality 1.75-inch compression drivers work together to deliver strong precision and clarity across the band. A carefully developed time-coherent waveguide ensures consistent sound dispersion and proper phase alignment between modules in a cluster.
Precise Coverage Through DSP and Waveguide Design
A built-in Class D amplifier delivers high energy efficiency, while an advanced DSP system with FIR filtering allows precise control over the system's response and fine-tuning to match a specific acoustic situation. A 100° H x 10° V coverage pattern gives very stable horizontal dispersion, which is key when building consistent line array clusters from multiple modules without gaps or overlaps in audience coverage.
Light Build, Ready to Fly
Thanks to neodymium magnet technology, each module weighs just 17 kg, making it easier to carry by hand, deploy quickly, and rig in flown configurations without extra lifting equipment. An IP45 rating lets the system run in demanding outdoor conditions, and available accessories, including the ST K4A wood stacking frame and the FLC K4A flying frame, support both ground-stacked and flown clusters. Paired with the SUB K15 A subwoofer, the system gains a full, balanced range with strong low-frequency support.
