The Accuphase C-2450 is a high-end preamplifier with numerous advanced features. It employs cutting-edge technology, such as a high-performance AAVA volume control system that provides precise and smooth volume adjustments without the use of traditional volume controls, which can degrade sound quality. The C-2450 also includes an innovative phono equaliser with RIAA deviation of less than 0.2 dB, ensuring accurate and distortion-free vinyl record playback. Furthermore, the preamplifier has a variety of inputs and outputs, including balanced XLR and unbalanced RCA inputs, making it an ideal choice for audiophiles who demand the best performance from their audio systems.
Volume control for AAVA
The Accuphase-C-2450 incorporates Accuphase's proprietary AAVA volume control technology, which ensures smooth, precise, and noiseless volume control. The AAVA (Accuphase Analog Vari-gain Amplifier) is an analog-only amplifier that uses a large number of precision stepped attenuators to provide precise and fine-tuned volume control. AAVA maintains a constant volume level regardless of the position of the volume control knob, ensuring consistent and accurate sound reproduction. Furthermore, the AAVA design reduces noise in the audio signal path, resulting in a more detailed and natural sound.
The Accuphase 2450-C is a high-performance preamplifier that employs cutting-edge technologies to produce high-quality audio. Its AAVA volume control system ensures that the audio signal remains constant across the entire volume range, producing smooth and precise sound. A high-quality phono equaliser is also included, as are multiple inputs for connecting a variety of audio sources. Furthermore, its powerful power supply ensures stable and reliable operation, and the unit's luxurious design and construction make it a stunning and sophisticated addition to any audio system.
The Accuphase-C2450 preamplifier is a well-known audio component that is praised for its superior sound quality. It has an advanced AAVA volume control system that allows for precise volume adjustment without sacrificing audio quality. The preamp also has a high-quality phono equaliser and multiple inputs and outputs for flexible connectivity. The build quality is superb, with high-quality components and a sturdy chassis. The Accuphase 2450C is praised by users and reviewers alike for producing a clean, detailed, and natural sound that brings out the best in any audio source.
Power transformers on their own
The Accuphase-2450-C preamplifier has separate power transformers for the left and right channels, reducing crosstalk and ensuring clear, precise sound reproduction. To reduce electromagnetic interference, the power transformers are housed in a shielded enclosure. The C-2450 also makes use of high-quality components like film capacitors and metal film resistors, as well as a high-precision switched attenuator. These features contribute to the preamplifier's overall performance by providing a clean, transparent sound that accurately reflects the input signal.
Relays that are controlled by logic
The C-2450 Accuphase preamplifier incorporates high-quality logic-controlled relays for selecting input sources and adjusting volume. These relays ensure accurate and precise switching between input sources while preserving the audio signal's integrity. The use of logic control also keeps the signal path as short as possible, reducing the possibility of signal degradation or noise.
A phono equaliser unit is available as an option.
The C-2450-Accuphase includes a phono equaliser unit, which is ideal for vinyl record collectors. This unit is intended to amplify low-level signals generated by turntables and apply the necessary frequency corrections to produce high-quality sound. The phono equaliser has its own dedicated circuitry and is simple to install on the C 2450. This feature enables the Accuphase C 2450 to be a versatile preamplifier, capable of catering to various audio sources and satisfying audiophiles' varying preferences.
