Know before you buy
Balanced AAVA eliminates the traditional variable resistor, ensuring that the signal path remains free from impedance changes. This results in superior signal-to-noise performance and prevents the sound degradation often associated with standard volume potentiometers.
The C-2900 does not come with a phono stage pre-installed. However, it features a dedicated slot for the optional AD-2900 phono equalizer board, which supports both Moving Magnet (MM) and Moving Coil (MC) cartridges.
Yes, the C-2900 offers three selectable gain settings of 12 dB, 18 dB, and 24 dB. This allows you to optimize the volume control range and sensitivity based on the specific power amplifier and speakers in your system.
The C-2900 includes a high-performance, dedicated headphone amplifier designed to drive a wide range of headphones with precision. It provides a clean, high-fidelity output that maintains the same sonic integrity as the main speaker outputs.
By using independent power supplies for each channel, the C-2900 prevents electrical interference and crosstalk between the left and right signals. This design significantly improves channel separation and contributes to a wider, more stable soundstage.
The C-2900 features a fully balanced circuit design throughout. While it provides both RCA unbalanced and XLR balanced inputs and outputs, the balanced XLR connections are recommended to take full advantage of the unit's noise-rejection capabilities.
