STEREOSTEREO PREAMPLIFIER
PREAMPLIFIER

The C-3900 is Accuphase's new flagship preamplifier developed to celebrate the 50th anniversary of thecompany's founding. Conventional preamplifiers attenuate the input signal by means of resistors and thenamplify the result, which leads to an increase in noise. By contrast, AAVA performs direct volume adjustment
through a combination of V-I (voltage-current) conversion circuits of different gain. Consequently, there are nochanges in impedance or frequency response and sound quality remains impeccable. Any changes in noiselevel depending on the selected volume position are kept to an absolute minimum, thereby realizing
outstanding S/N ratio also at commonly used listening levels. In the C-3900, the Balanced AAVA principle
using two balanced AAVA circuits is further elevated by driving two such units in parallel, resulting in Dual
Balanced AAVA which reduces the noise level by a further 30 percent compared to previous models. The
volume sensor mechanism ensures utterly smooth operation with a solid feel and highly accurate volume knob
position detection. The C-3900 is a top-of-the-line preamplifier that brings music to life with an emotional
appeal such as never known before. Connecting the Stereo Phono Amplifier C-47 enables high-quality
reproduction of analog records as well.

The C-2900 features a balanced circuit from input to output by implementing "Balanced AAVA", which is aunique volume control. Noise is reduced by configuring the major circuits with discrete parts and optimizing
the gain allocation, while rugged aluminum frames separate the left and right channels to suppress bothelectrical interference and vibrations. These technical approaches reduce noise levels in the C-2900 byapproximately 20% over conventional models and control the volume while preserving the vibrancy of thesound source. It also includes Accuphase’s original advanced volume sensor for smoother and quieter volume

Every audio component draws all of its energy from the power supply. The Clean Power Supply
components from Accuphase are products that remove noise and impurities from the AC powerline through a groundbreaking new approach, resulting in a drastic improvement of the soundand picture quality of connected audio and video equipment. Without relying on an oscillator,
the reference waveform is created with further improved accuracy and is linked to the power
section by a balanced connection to ensure incredibly low distortion in the output waveform.
Because the circuitry is fully analog and the input and output frequencies are exactly the same,the unit itself does not generate any high-frequency noise. The PS-1250 can supply up to 900
VA and the PS-550 up to 400 VA to audio components, resulting in a dramatic sound quality
improvement with any system. A built-in meter allows monitoring of output power, input/output
voltage, and distortion. Input/output waveform display is also available.
