Accuphase Precision Stereo Preamplifier C-2450

Accuphase C-2450

The new C-2450 was launched, inheriting the superior technologies from Accuphase flagship Preamplifier C-3850 and C-2850. Thoroughly seeking the ultimate in the high fidelity music playback, Accuphase is confident that the C-2450 will draw you into the world of true musical performance and soak up the inspired ambience. C-2450 is the 4th generation high-end pre-amplifier descended from brilliant C-2400 series. C-2450’s technical feature is 10 % lower noise performance than C-2420, achieved by the improved AAVA (Accuphase Analog Vari-gain Amplifier) volume control circuit.

The utterly smooth feel of the volume control assembly and a top plate of brushed aluminum with a hairline finish, demonstrate a level of dedication and hands-on craftsmanship that pervades every aspect of this preamplifier. Each C-2450 is individually honed to provide nothing short of perfection. Precision Stereo Preamplifier.

Innovative: At the leading edge of technology

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 full mono construction. The entire circuitry from the input, through to the output, benefits from a strong and stable supply of current. This substantially enhances the quality of the musical signal.

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 discrete. 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.

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.
Although AAVA adjusts the volume level by combining the output of weighted amplifiers, it is operated using a volume knob that appears similar to conventional systems. Internally however, there are major differences. The volume sensor mechanism that detects the angular position of the volume knob, rests on a frame extruded from a massive aluminum block and is finished with utmost accuracy. The volume knob feels both responsive and solid when rotated, and ensures extremely accurate position detection. The entire mechanism is supported on the chassis by a floating suspension using insulators, which has the added advantage of extremely quiet motor-driven operation when the remote commander is used.
