Pro-Sound Class-D Amplifier, 2x 700 W, digital




These digital (Class D) 2-channel 19˝ power amplifiers
(1 RU) are ideal for the use in professional acoustic sounding devices.
The devices are manufactured in state-of-the-art production processes using high quality components.
They have been designed for continuous operation. They are absolutely short circuit and open circuit proof and are equipped with all relevant protection devices.


  • The Led`s on the front inform about important signal and operating conditions
  • Special protective circuit against open circuit, short circuit, overhead and a power up delay are naturally.
  • The speaker outputs are designed for 8 ohms, 4 ohms or 2 ohms operation and suitable to be used in almost all types of speaker in the corresponding output classes.
  • Across the digital technology there is a very high efficiency of the amplifiers which achieves results in a very low heat development (natural life of the devices) and a relatively low power consumption.
  • The amplifiers have protection circuitry against short circuit, overheating, power up delay, DC fault protection and a clip limiter to prevent overloading the speakers.The front panel of the amplifiers is designed that all important information’s about the operating status are visually. These indicators are: power LED display, clip LED display, protect and signal LED.
