Accuphase C-2900 Precision Stereo Preamplifier

The C-2900 is a reference-grade preamplifier for listeners who want precise, vibrant control over their system without stepping up to the very top of the range.

Its Balanced AAVA volume control is designed to preserve the life in a recording rather than dulling it the way a conventional resistive volume pot can. You get a generous set of connections (five line inputs, two balanced, plus dedicated recorder and external-preamp loops), individual phase settings per input, a discrete headphone amp, and the option to add analog playback later via the matching AD-2900 phono module.

• 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
• Subsonic filter that cuts off ultra-low frequency noise from record warping
• Natural grain wood case with a mirror finish crafted by artisans using carefully selected virgin wood
• High-carbon cast iron insulator feet with superior damping characteristics
• Adding the AD-2900 to the C-2900 allows you to play analog discs.
  
• Front panel switching function for using a phono equalizer expansion unit
  • MC/MM switching
  • MC load impedance switching (10 / 30 / 100 / 200 / 300 ohms)
  • Gain switching (MM: 34 / 40 dB, MC: 64 / 70 dB)
