Accuphase C-2900 Precision Stereo Preamplifier

To celebrate the 50th anniversary of Accuphase's founding, the development of a new flagship model to incorporate the entire wealth of the company's experience was begun. Now, after five years, the work is complete. The C-3900 represents an uncompromising harmony of technology and sensibility, boasting ultimate performance and sound quality that ushers in a new era of the preamplifier.

The Dual Balanced AAVA design with two balanced AAVA circuits delivers sonic excellence that is transparence itself. Volume adjustment is realized while retaining all the vibrant energy and richness of detail that is the life breath of an artistic performance. The supple elegance of music as reproduced by the top-of-the-line C-3900 is a moving experience that reflects the impressive depth of Accuphase know-how.

FEATURES

  • Balanced AAVA volume control
  • Logic-controlled relays for signal switching assure high sound quality and long-term reliability
  • Printed circuit boards for signal transmission use glass cloth fluorocarbon resin with low dielectric constant and minimum loss along with gold-plating on copper foil surfaces
  • Power supply circuits with separate toroidal transformers and filtering capacitors (10,000 μF × 4 pcs) for the left and right
  • Newly developed volume sensor construction for a quiet and smooth operation feel
  • Versatile arrangement of inputs and outputs (five line level inputs, two balanced inputs, two line level outputs, and two balanced outputs)
  • Line level input and output connectors for a recorder
  • Line level and balanced EXT PRE inputs for connection of an external preamplifier
  • Individual phase setting for each input
  • Switchable overall gain (12 dB / 18 dB / 24 dB)
  • Left / right balance control through Balanced AAVA
  • Stereo signal can be switched to monophonic operation
  • Volume attenuator to instantly reduce sound to as low as –20 dB
  • Loudness compensator for correcting the perceived spectral balance
  • Informative and easy to read input and volume level display with on / off switching
  • Discretely configured, high-quality headphone amplifier with parallel push/pull output stages
