Description
Monophonic power amplifier Accuphase The A-300 is designed for high-end audiophiles who demand the highest possible sound quality, performance, and precision in speaker driving.
Monophonic power amplifier Accuphase A-300
Monophonic power amplifier Accuphase The A-300 is a premium monoblock power amplifier razredto A, which delivers exceptional sound performance, low noise levels and superior craftsmanship. It is the successor to the model A-250, with the A-300 raising the bar to a new level with improved power, precision and sound quality.
Created for the company's 50th anniversary Accuphase, the A-300 redefines the ideal of power amplifiersreda A. The output stage with 20 parallel push-pull MOS-FET transistors improves performance by 25% compared to conventional models and provides output power 125 W at 8 Ω, 250 W at 4 Ω, 500 W at 2 Ω and 1.000 W at 1 Ω, which enables extremely stable voltage amplification. The fully discrete balanced input amplifier achieves a level of silence that will completely immerse you in the music and make you forget you are listening to audio equipment.
The A-300's unrivaled expressiveness allows you to enjoy the most beautiful works of the world's greatest composers.
Main features
- Clean roomred A-operation – provides extremely natural, warm and detailed sound without switching distortion.
- Strong output power – 125 W at 8 Ω, which doubles when the impedance is halved, reaches 1.000 W at 1 Ω.
- Extremely low noise – 20% lower noise level than the A-250 model, enabling crystal clear sound.
- Damping Factor 1.000+ – excellent nadzor nad speakers and improved sound dynamics.
- MOS-FET transistors in push-pull configuration – tenfold increaseredThis circuit reduces the output impedance and increases the power.
- High power toroidal transformer – reduces magnetic field leakage and improves power efficiency.
- Filter capacitors 100.000 μF – stabilize operation and reduce voltage ripple.
- Digital power meter – shows the actual output power, independent of the speaker impedance.
- Gain switch – four settings (Max, –3 dB, –6 dB, –12 dB) to adjust signal strength and reduce noise.
- Balanced Remote Sensing – reduces output impedance, improves damping factor and reduces distortion.
- MOS-FET switches instead of mechanical relays – improve sound quality, reliability and reduce contact resistance.
- Napredon protection – short circuit, overheating and overcurrent detection, with visual warning on power meters.
- Robust and aesthetic design – aluminum housing, gold-plated connectors and exceptional build quality.
