Accuphase E-5000

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 poweramplifier 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.

•  Balanced AAVA volume control
• Highly reliable logic-control signal switching relays
• 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
• Protection circuitry using low impedance, highly reliable MOS-FET switches
• Two massive speaker connectors for output switching and simultaneous output
• Line level and balanced outputs at the preamplifier section support bi-amping connection
• Line level and balanced inputs at the power amp section allow use as a power amplifier
• Dedicated, high-quality headphone amplifier constructed with discrete components
• Two expansion slots for option board
