    3. VOLTAGE REQUIREMENTS The KH15 operates safely and without audio discontinuity if the AC voltage stays within either of two operating windows: 95-125 (voltage selector on 115 V) or 195-250 V (voltage selector on 230 V), at 50 or 60 Hz.

  • Page 7: Current Requirements

    4. CURRENT REQUIREMENTS The KH15 presents a dynamic load to the AC mains, which causes the amount of current to fluctuate between quiet and loud operating levels. Since different cables and circuit breakers heat up at varying rates, it is essential to understand the types of current ratings and how they correspond to circuit breaker and cable specifications.

However there are wide variations internationally in the regulations and practices applying to suspension of sound systems in public places.

  • Page 18: Maintenance Of The System

    13. MAINTENANCE INSPECTION AND MAINTENANCE The K array flying systems are an assembly of mechanical devices, and are therefore subject to wear and tear over prolonged use, as well as damage from corrosive agents, extreme impact, or inappropriate use. Such inspection includes examination of all load-bearing components for any sign of undue wear, twisting, buckling, cracking, rusting, or other corrosion.
