C-2900 är ett helt nytt försteg från Japanska Accuphase. C-2900 har mycket teknik hämtat från Accuphase flaggskepp C-3900 och går även att utrusta med Accuphase stora Riaa-kort, AD-2900.
C-2900 är ett av de absolut bästa förstegen vi hört i prisklassen, rekommenderas varmt!
Finns i butiken för demo!
Egenskaper
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.
