For more than half a century, Accuphase has continued its relentless pursuit of creating the ideal volume control circuitry. The C-2300 preamplifier utilizes Balanced AAVA – the successor of the AAVA system – to control volume without sacrificing vibrancy in the source sound. A newly added 4-band tone control enables fine adjustments to sound tone. Experience the sonic depth from the combined sound quality and superior features the C-2300 provides.

• Balanced AAVA volume control
• 4-band tone control
• Quiet and smooth volume sensor construction
• Ample inputs: 5 Line and 2 Balanced
• Independent power supplies and unit amplifiers for left and right
• Phase setting memory for each input
• Highly reliable logic-controlled signal switching relays
• High-quality headphone amplifier
• Additional option boards support digital signals and analog records
