SCL AMP-8510A Class-A Single No-NFB Power Amplifier

High-performance amplifier providing the ultimate sound quality experience

The AMP-8510A is an innovative semiconductor Class-A single non-reverting amplifier designed to exceed the expectations of music lovers. It is a product of technology and dedication to pushing the limits of sound quality.

A choice of semiconductors, unlimited sound quality experience

The AMP-8510A offers a choice of the following four output semiconductors:

MOS-FET (Metal-Oxide-Semiconductor Field-Effect Transistor)

MOS-FETs are widely used in audio amplifiers because of their very high switching speed and efficiency; their distinctive advantage is their high input impedance and low output impedance. This gives MOS-FETs the ability to deliver large currents with minimal degradation of sound quality.

SiC (Silicon Carbide)

SiC is a semiconductor material with excellent properties that allow it to operate in high temperature and high voltage environments; SiC devices are ideal for audio amplifiers that require high efficiency and high output power. SiC also offers low on-resistance and fast switching, resulting in clear sound quality with low distortion.

GaN (Gallium Nitride)

GaN offers superior performance in audio amplifiers due to its very fast switching performance and low on-resistance. GaN devices are capable of high-frequency operation, resulting in more accurate and dynamic sound reproduction. GaN can also offer even higher efficiency compared to SiC.

Ultra-low output impedance MOS-FETs

Ultra-low output impedance MOS-FETs are specially designed MOS-FETs with extremely low output impedance. This type of MOS-FET minimizes signal distortion and provides pure and clear sound quality. Its high driving capability also allows precise control of the speaker and reproduction of the finest nuances of music.

The above four semiconductors are the crystallization of semiconductor technologies that play an important role in high-performance audio equipment. These technologies have become indispensable elements in modern high-end audio equipment, providing a richer and clearer musical experience. The unique characteristics of each semiconductor allow you to enjoy minute differences in sound quality and achieve the ideal sound.

Unparalleled Sound Quality and High Precision

With an output of 10W at an 8Ω load, the AMP-8510A has a distortion of only 0.025% at 1W and a frequency response from an astonishing 10Hz to 100kHz. Furthermore, it has the amazing characteristic of passing up to 1 MHz in sine wave, which allows music details to be expressed with breathtaking clarity.

Unparalleled driving power due to direct-coupled design

The greatest feature of the AMP-8510A is that the output semiconductors are directly connected to the speakers without any intermediary between them. This design is impossible to achieve with complementary PP (push-pull). The output power is 10W and the bias current is 1.8A, which requires a larger bias current due to the characteristics of a single Class-A amplifier. Due to this direct-coupled design,The direct-coupled design allows the fine nuances of sound that were previously inaudible to be reproduced clearly, even with SATRI-LINK connections using current signal transmission. The benefits of the direct-coupled design bring out the finest details of music even more clearly, enabling an unprecedentedly deep sound experience.

Precise Control with Digital ATT

The digital ATT (attenuator) using a long-life relay allows precise gain adjustment in 0.5dB steps. Attenuation is displayed numerically and volume settings are intuitive, making it easy to adjust the ideal volume balance.

SATRI-LINK for every detail of sound

Equipped with SATRI-LINK for current signal input, the ultimate amount of information can be obtained by connecting to Bakoon Products / SCL DACs, phono amplifiers, and preamplifiers. You will rediscover the depth of music.

Perfect speaker control and short delay time

The DF (Damping Factor) of the speaker control is very stable at 72.7, 72.7, and 57.1 at 1W, 5W, and 10W, respectively, for optimal speaker control. In addition, a short delay time of 25ns (nanoseconds) ensures extremely fast signal processing and high speed reproduction.
