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.

Höjdpunkter:

• 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.

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.
