This preamplifier combines high-fidelity performance with unparalleled control. The heart of the C-2300 lies in its innovative Balanced AAVA volume control, preserving the vibrancy of your source material at any listening level.\u003c\/p\u003e\u003cp\u003eThe Precision Stereo Control Centre C-2300, while inheriting the outstanding design approach and technology of models such as the C-2150 and C-2450, also brings more control over tone, as well as a further reduction in noise levels.\u003c\/p\u003e\u003ch3\u003eBalanced AAVA volume control\u003c\/h3\u003e\u003cp\u003eConventional preamplifiers use variable resistors to adjust volume, which causes contacts to deteriorate and create grit as well as increase noise at normal volume levels. AAVA, however, produces multiple, widely varying signals from the input signal and controls volume by changing the combination of those signals. This achieves minimum noise at all volume levels without any grit. The C-2300 with its balanced AAVA circuits delivers exceptional noise suppression performance.\u003c\/p\u003e\u003ch3\u003eSeparate unit amplifiers\u003c\/h3\u003e\u003cp\u003eThe C-2300 features separate power supplies for left and right channel, each with a dedicated power transformer, filtering capacitors and peripheral circuitry. The various unit amplifiers are also entirely separate for the two channels, arranged on a motherboard in fully monaural construction. This prevents unwanted crosstalk and interaction both on the electrical and the physical plane.\u003c\/p\u003e\u003cp\u003eThe power source driving the circuits can greatly affect sound quality. Each side of this preamplifier features a high-quality transformer housed inside its own case. The two 10,000 μF high-capacity, high-quality custom-made filtering capacitors mounted on each side supply power with margins and are highly impervious to load fluctuations.\u003c\/p\u003e\u003cp\u003eThe Accuphase C-2300 has a full range of functions suitable for a control center, and is equipped with a total of 4 bands of tone control with BASS, TREBLE, and MID 2 positions, allowing detailed tone adjustments.\u003c\/p\u003e\u003cp\u003eA range of sophisticated option boards opens up even more possibilities. The newly developed Digital Input Board DAC-60 features a USB port and support for high-bit, high-sampling frequency signals up to 384 kHz\/32 bits. This allows for reproduction of high-quality music residing on a computer. The DAC input selector button makes it easy to switch between the optical, coaxial, and USB input. The newly developed Analog Disc Input Board AD-50 is also available, ideal for high-grade reproduction of analog records using either MC or MM phono cartridges.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eFrequency Response:\u003c\/strong\u003e BALANCED\/LINE INPUT, 3 - 200,000Hz +0 -3.0 dB, 20 - 20,000Hz +0 -0.2 dB\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eTotal Harmonic Distortion (for all inputs):\u003c\/strong\u003e 0.005%\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eInput Sensitivity:\u003c\/strong\u003e BALANCED 252mV, 0.5V Output 63mV.
