Accuphase C-2900
High-End försteget C-2900 är den femte generationen med AAVA volume control system och med teknik hämtat från C-3900!
Volymkontrollen i en förstärkare är en viktig komponent för att bibehålla livlighet i ljudkällan. Sedan sin grundande har Accuphase ägnat 50 år åt att sträva efter att skapa den perfekta volymkontrollkretsen. C-2900:s Balanced AAVA-system har utformats med hjälp av Accuphases ursprungliga AAVA volymkontrollkretsar för att väsentligt förbättra ljudprestanda. Den trogna återgivningen av delikata musikframträdanden av C-2900 gör den till den perfekta försteget för passionerade ljudälskare.
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.
