Product Features
The Accuphase P-4500 is a stereo power amplifier that is designed to produce high-quality sound. Its amplification circuitry is based on a push-pull design with a dual power supply, ensuring accurate and distortion-free music reproduction. The P-4500's 450 watts per channel into 1 ohm power output ensures that it can easily drive even the most demanding speakers.
Accuphase's AAVA volume control system, which employs multiple variable gain amplifiers to provide smooth, precise volume adjustment without adding coloration to the sound, is also included in the amplifier. The P-4500 is constructed with high-quality components, making it a dependable and long-lasting investment for any audiophile.
Amplification of power
The Accuphase-P-4500 power amplifier is a pure class A design that incorporates a high-quality instrumentation amplifier as well as a large toroidal transformer. The parallel push-pull amplification in the amplifier provides high output power while minimizing distortion and noise. With 450 watts per channel into 1 ohm, the P4500 is capable of driving even the most demanding speaker systems. Accuphase's original Dynamic Power Supply is also included in the amplifier, ensuring stable and noise-free power delivery to the amplifier circuits, resulting in superior sound quality.
500 W power output
The Accuphase-P4500 power amplifier is capable of producing 500 watts of output power. This is made possible by the power amplifier section of the amplifier, which includes a balanced amplification circuit as well as a large toroidal transformer with a high capacity power supply. The amplifier also has a low output impedance, which contributes to stable and accurate amplification even at high output levels. This powerful amplifier is suitable for a variety of audio applications, including home theater systems and professional recording studios.
Instrument amplification
The Accuphase 4500P is equipped with an instrumentation amplifier and a three-stage Darlington connected amplification circuit for ultra-low distortion and a high S/N ratio. With a frequency range of 20 Hz to 20 kHz, it employs the MCS+ topology for high-speed amplification and excellent linearity. The amplifier also includes a newly developed high-efficiency power MOS-FET output stage, which ensures stable and powerful driving capability. The instrumentation amplifier contributes to the superior sound quality of the P 4500, making it an excellent choice for audiophiles who require high-fidelity sound reproduction.
Design
The P-4500 Accuphase has a sophisticated and elegant design with a symmetrical layout that reduces noise and distortion. For optimum sound quality, the amplifier is constructed with high-quality materials such as a large toroidal power transformer, high-grade capacitors, and high-precision resistors. The front panel has a traditional design with large rotary knobs for volume and source selection. To provide a solid foundation for the electronic components and to reduce external vibrations, the chassis is made of high-rigidity aluminum alloy.
