The new Class D digital power amplifier D-AMP-500 with 500 W power and D-AMP 8x60 with 8x60 W power impress by their high efficiency in a very compact design (2U). The digital technology allows for energy savings of about 42% at full output compared to analog power amplifiers!

The Class D amplifiers with optimized output filter offer load-independent frequency response and are equipped with a floating transformer output with taps for 100 Volt, 70 Volt and 4 ohms. A stable output voltage with very low level difference between idle and full load (<1dB), short- and open circuit-proof and low harmonic distortion (<0.5%) are other features of these highly efficient amplifiers. The electronically balanced input has a sensivity of 0 dBu = 0.775 V. Both digital amplifiers can be operated from 19 to 30V DC via battery.

The D-AMP Series is especially designed for 20 kHz monitored public address systems by very low intermodulation between audio and the 20 kHz test signal and well filtering of switching frequencies.

  • Output stage in Class D
  • Emergency 24V power option
  • Limiter
  • Subsonic filter
  • Variable speed forced cooling.
