  • Over-temperature forecasting
  • Thermal, short-circuit and overload protection
  • Temperature controlled air cooling system
  • Clip and permanent signal limiter
  • Digital gain attenuation
  • Interactive LCD matrix
  • PC remote control, monitoring and diagnostics

Applications

  • Live sound reinforcement
  • Fixed installations

Occupying only 1U of rack space, weighing a mere 8kg (17.6lbs) and, with 2 x 2600 watts output into 4 ohms, the MA5.2K is a cost effective, high performance solution to many amplification requirements.
