Modular Professional Power Unit 250W - 70/100V. This new series of audio power amplifiers was designed to fulfil an evolving market in the most flexible and professional manner. The new range responds to precise operating criteria and was designed and tested to guarantee total reliability of use, also with continuous operation. Thanks to the use of power supply switching with SMPS (switch mode power supply) technology and to the constant voltage output 70/100V obtained electronically without transformers, it was possible to design the amplifier in only one rack unit, succeeding in containing the weight and size. La serie DM Power è stata concepita per essere installata in cestello rack 19” 3U in grado di accogliere n° 8 moduli affiancati.
