DPA Series SPECIFICATION CONFIGURATION

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.

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