Accuphase C-2900

The preamplifier’s volume control is a vital component for maintaining vibrancy in the sound source.
Since its founding, Accuphase has spent 50 years in pursuit of creating the ideal volume control circuitry.
The C-2900’s Balanced AAVA system was designed using Accuphase's original AAVA volume control circuits to significantly improve sonic performance. The faithful reproduction of delicate musical performances
by the C-2900 makes it the perfect preamplifier for passionate audiophiles.

• 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)
• Mått: (BxHxD) 477x156x412mm
• Vikt: 24,2 kg

Option: Dedicated add-on

Phono Equalizer Unit

Analog records can be reproduced by installing the dedicated phono equalizer unit AD-2850 in a rear-panel slot.
The AD-2850 features separate input circuitry for MC and MM cartridg- es to ensure optimum matching and realize outstanding S/N ratio. The built-in differential RIAA equalizer circuit is designed to provide super accurate RIAA equalization characteristics. The printed circuit boards are made from glass cloth fluorocarbon resin and housed in a sturdy aluminum enclosure to minimize any kind of external influence.
