Powerful and Energy-saving
The digital mono PA power amplifier PA-1250D is part of a new equipment generation which combines a high power capability with an efficient energy utilisation, thus making an important contribution to climate protection. Furthermore, the user also saves electricity costs. Among other things, this is due to the digital 100V power amplifier providing a considerably higher efficiency of more than 90% compared to analogue units (approx. 70%). Furthermore, the thermal loss is considerably lower. Thus, the cooling requirements will be minimised and the service life of the PA-1250D will be further increased.
Digital mono PA power amplifier, with an energy-saving effect.
  • 1 x 250 W
  • Class D concept with a high efficiency of more than 90% to reduce energy costs
  • Additional integrated energy-saving functions, e.g. unit automatically goes to standby mode when no input signal is present (as soon as an input signal is detected, the amplifier is automatically switched on again)
  • Requires a significantly lower rechargeable battery capacity for emergency power operation than 100 V analogue amplifiers
  • Clearly reduced cooling requirements due to low heat dispersion
  • Maintenance-free cooling and silent operation due to fanless cooling concept, thus especially suitable for noise-sensitive areas, e.g. offices, conference rooms or churches
  • Special protective circuits prevent damages caused by short circuit or overheating
  • Extensive, menu-controlled settings
  • Switchable 200 Hz high-pass filter, 6 dB/oct.
  • Additional priority input
  • LCD for the operating parameters
  • Mains operation or 24 V emergency power operation
