Did you check out the feature-packed Accuphase C-2450 Precision Stereo Control Centre? It’s now available on Tecnifi. Amalgamating the purely analog AAVA volume control circuit with functionally sophisticated technology inherited from the C-2850 results in a superb S/N ratio and a refinement of expression that reflects new clarity to the music. The supremely smooth operation feel of the volume sensor assembly and a top plate crafted of brushed aluminum with a hairline finish reflect a level of dedication and hands-on craftsmanship that pervades every aspect of this preamplifier. Each C-2450 is individually honed to impress with an unprecedented level of perfection.
AAVA operation principle is purely analog
The AAVA circuit converts the input music signal into 16 types of weighted currents which are then combined according to the position of the volume control knob. The combination of signal currents forms a variable gain circuit that adjusts the level of the music signal.
High-accuracy, high-rigidity volume sensor assembly with responsive yet solid feel
Separate unit amplifiers for left and right
The main amplification tasks such as input buffering, AAVA, balanced output, and headphone output are handled by a total of six modular amplifiers for each channel. These unit amplifiers are mounted on a glass epoxy motherboard, with left and right sections being kept completely separate. In order to eliminate unwanted mutual interference between the amplifiers, a sturdy frame is used to provide support. As a result, both electrical interference and physical vibrations are reliably suppressed, creating an ideal operation environment.
Separate left/right power supplies
The power supply circuitry not only acts as the energy source of an amplifier, the current that it supplies to the load also has a significant influence on sound quality. The C-2450 incorporates four custom-made filtering capacitors which are rated for 10,000 μF and have been specially tuned for optimum sonic properties. Along with the power transformer, the entire power supply section is duplicated and kept separate for the left and right channel, resulting in a full mono construction. The entire circuitry from the input right through to the output benefits from a strong and stable supply of current which enhances the quality of the musical signal.
