The CA 1515-9 - SP is an active plug-and-play full-range system with powerful bass reproduction for high quality, assertive near field and medium-range sound reinforcement. Even in situations where relatively little equipment is in use, the CA 1515-9 - SP, with its precise radiation characteristics, achieves a broad and extremely homogeneous acoustic coverage. Natural reproduction of speech and music, even at very high volume levels, characterize the CA 1515-9 - SP. Additional subwoofers can often be dispensed with, even when increased bass response is required. A special phase alignment in the CA 1515-9 - SP optimizes parallel operation with all K&F SP series subwoofers. Whether as active stage monitor or complete P.A. system; the simple handling and high performance are convincing in a wide range of applications, both in mobile use and installed in theatres, opera houses, discos, live clubs, all-purpose halls or TV and radio studios. The fan-free system electronics contain the convection-cooled and highly efficient digital 1 kW Class D power amplifier and take care of the specific basic equalization. The elaborate limiter section with RMS and peak limiters ensures a high level of operating safety. Thus equipped one can do without the addition of a controller. The multifuctional enclosure with 5 flying points, carrying handles and stand adapter make for a quick and secure set-up. The CA 1515-9 - SP is without doubt a highly flexible tool in the highest category of professional active systems.
