ACCUSTIC ARTS® POWER I: The long-term audiophile hit

The long-term audiophile “hit” and brilliant integrated power amplifier ACCUSTIC ARTS® POWER I is manufactured since 2002. The current version once again exploits a tried and tested circuitry technology and includes a number of improvements.

POWER I highlights

  • Audiophile integrated stereo power amplifier with high output
  • 12 selected Bipolar output transistors of highest quality
  • Encapsulated 500 VA toroidal core transformer of premium quality for high output reserves; separate windings for preamp section and for power amp section
  • Integrated, switchable headphones amplifier of premium quality
  • Very good smoothing thanks to more than 80,000 µF power supply capacity
  • High damping factor for high output reserves
  • Integrated protective circuit switches ascents off when clipping, HF oscillations, too high temperature or too high DC offset occurs
  • Constant low operating temperature due to generously dimensioned heat sink
  • 2 x balanced high level inputs (XLR)
  • 3 x unbalanced high level inputs (RCA/Chinch), can be configured as high-level input or “SURROUND-BYPASS”
  • 1 x unbalanced pre-output (RCA/Chinch), configurable as RECORD output or preamp output
  • Separate level adjustment for each input
  • Premium quality, gold-plated speaker terminals
  • Premium quality, long-term stable relays
  • Highly accurate microprocessor controlled volume control
  • Encapsulated high grade volume potentiometer Full metal housing for optimum shielding
  • Front panel made of brushed aluminum; turning knobs/push buttons made of massive and chromed brass
  • ACCUSTIC ARTS® remote control RC II
  • ACCUSTIC ARTS® POWER I is “Handmade in Germany”
