Product Brand : Accuphase
Product Name : A47 CLASS-A 45W/ch STEREO POWER AMPLIFIER
Product Genre :
Condition : NEW
Description:

The history of Pure Class A power amplifiers from Accuphase began in 1978 with the introduction of the model P-400. The company has been perfecting the technology ever since, developing numerous technologi- cal improvements along the way. The A-47 is a succes- sor model to the A-46, based on the design technology developed for higher-ranked models. It is a full-fledged Pure Class A Stereo Amplifier that produces truly captivating sound.

The output stage of the A-47 uses high-performance power MOS-FETs ideal for audio applications. For each channel, six devices are arranged in a parallel push-pull Pure Class A arrangement. This results in very low output impedance, ensuring that constant drive voltage is available also for low-impedance loads. Superior performance is evident from the linear power progres-

sion of 45 watts into 8 ohms, 90 watts into 4 ohms, and 180 watts into 2 ohms. The amplifier is even capable of driving ultra-low 1-ohm impedances with an amazing 360 watts (music signals only).

The input stage circuitry is configured as an instrumen- tation amplifier. This approach makes it possible to achieve fully balanced signal paths, extending from the signal input all the way to the final power amp stage. Extremely low-distortion, low-noise op amps are used in the input stage, combined with measures to prevent any risk of noise intrusion from the input circuitry. As a result, S/N ratio has been further improved.

The A-47 not only eliminates any possible internal source of noise or distortion, as demonstrated by its outstanding performance ratings, it is also highly impervious to changes in ambient conditions. As a

consequence, operation stability and reliability which are crucial for a power amplifier have been dramatically enhanced.
Only the finest parts and materials, selected as a result of a series of strict testing are used in the A-47. Latest circuit topology raises electrical performance by another notch, ensuring excellent long-term reliability and producing a further improvement in sound quality. The front panel of the amplifier prominently features two large analog power meters, with switchable peak hold and sensitivity. An on/off switch for the meters is also provided. Using the A-47 in bridged mode creates a mono amplifier with even more impressive power output capability, rated for 180 watts into 8 ohms, 360 watts into 4 ohms, and 720 watts into 2 ohms (music signals only).
