Accuphase E-5000 Class AB Precision Integrated Stereo Amplifier

ON DISPLAY IN OUR STORE

The E-5000 is the flagship high-power Class AB integrated amplifier developed to mark Accuphase’s 50-year
anniversary. The preamplifier section features our superior Balanced AAVA volume control, while the power
amplifier section includes an instrumentation amp and power transistors in a five-fold push-pull arrangement
driven in Class AB. These circuits create a balanced circuit from input to output. With its precisely balanced circuits and solidly built output stage, the E-5000 integrated amplifier presents every piece of music in exquisite detail.

• Ample input connectors (Five line level and two balanced)
  
• Line level input and output connectors for a recorder
  
• Individual phase setting for each input
  
• Stereo signal can be switched to monophonic operation
  
• Left / right balance control through Balanced AAVA
  
• Volume attenuator that can instantly reduce sound as low as –20 dB
  
• Loudness compensator to adjust audible sonic balance
  
• Tone controls using summing active filters
• Power amplification stage employs instrumentation amplifier principle
  
• Current feedback amplification circuit topology assures excellent phase characteristics in high range
  
• Speaker output protection circuit guards against short-circuiting
