Qam, Measurement Power Amplifier

  • High power and light weight measurement amplifier, combining 2.3 kg weight weight with 800 Watt output in a small robust housing.
  • The amplifier is DSP controlled, with a very straightforward operation. Included is a white/pink noise signal generator. The internal signal module provides low crest noise signals to be able to reach high power levels from sound sources or electromagnetic shaker. External input of signal is equally possible, with spectral linearisation or without. This can be used for music, RASTI or any other signal.
  • Low frequency tuning in third-octave bands in the equalization mode over 31 to 200 Hz bands.
  • The standard Qam software is optimized for use with a Qohm or Qom sound source. With a setting for linearisation of the frequency spectrum. Other software versions are available for other products. A 20s pulsating mode for facade isolation or lng distance sound transfer measuremets is provided.
  • The high voltage output, 150 Volt pk-pk, and current limit of 56 Ampere pk-pk allows combination with a wide range sound sound sources or electromagnetic shakers.
  • A remote control is integrated to allow activation/deactivation of the amplifier up to 100 m.
