TERATON ALPHA, The Essence of A&K Audio Technologies

Superior headphone amplifiers achieve genuine and unaltered sound reproduction by not only ensuring a stable output but also meticulously designing and implementing each aspect, including power, noise, signal transition, circuit structures, and more.

The AK PA10, while compact and portable, seamlessly interfaces with a diverse range of headphones and IEMs. It is further enhanced by the incorporation of TERATON ALPHA technology, Astell&Kern’s ultimate sound solution. This technology enables the playback of ultra-high-quality sound without any distortion.

TERATON ALPHA, the result of extensive research over many years, represents Astell&Kern’s distinctive approach to achieving audio playback that faithfully preserves the original sound. It accomplishes this through effective power noise removal, efficient power management, unwavering amplification, and a fully converted audio output interface.

The AK PA10 has been meticulously developed as the embodiment of TERATON ALPHA, delivering pure and immersive analog sounds for an unparalleled audio experience.

Experience Distortion-Free Analog Sound with Class-A AMP

Class-A amplifiers are renowned for providing the best linear output, delivering soft, warm, and natural sounds by amplifying signals without introducing distortions or defects. This sought-after amplification method is highly favored by music enthusiasts, even though it has traditionally been considered impractical for portable audio devices due to its high power consumption and the challenges of implementing it in small devices.

The AK PA10 breaks these barriers by integrating a Class-A amplifier based on Astell&Kern’s unique circuit design technology, ensuring the delivery of signature analog sounds.

Employing a distinctive circuit design from Astell&Kern, the AK PA10 not only reduces power consumption but also increases output while effectively eliminating noise. This design is specifically crafted to bring the exceptional sounds of a Class-A amplifier to any location and at any time.

Introducing the AK PA10, Astell&Kern’s first portable Class-A amplifier, allowing you to enjoy the rich analog sounds through your portable devices without compromising on quality.

Class-A Current Control – Elevating the Analog AMP Experience with Intense and Spatial Sound

Headphone amplifiers go beyond merely providing the necessary output for headphone operation. The AK PA10 takes it a step further by meticulously controlling the current to match different headphones and IEMs, resulting in a more immersive and spatial sound reproduction.

The AK PA10 introduces a three-stage control of Class-A amplifier current, accentuating the distinctive characteristics of Class-A AMP in relation to the current value and producing a more intense audio experience. Addressing the concern of battery drain associated with power consumption—often a hindrance for Class-A AMPs in portable devices—the AK PA10 adeptly manages the current value.

This three-stage current control option empowers users to tailor the sound to the unique characteristics of their headphones and IEMs. Immerse yourself in the textured and spatial sounds that the AK PA10’s Class-A AMP can finely craft, offering a heightened audio experience that caters to your individual preferences.

Immersive Sound Precision with Gain Control

To capture the intricate details in music across different headphones and IEMs, a robust amplifier output is essential.

When utilizing the balanced input, the AK PA10 boasts an impressive capability, supporting up to 6.2 Vrms output at high gain. Tailor the gain level to match the unique characteristics of your headphones and IEMs, ensuring a crystal-clear and vivid sound experience.

With AK PA10, unlock the full potential of your audio device, delivering an unparalleled audio output that accentuates the richness and subtleties of your favorite music. Choose the optimal gain setting to enjoy a truly immersive and refined sound output.

Revolutionary 4.4mm In/Out True Balanced Circuit Design

Unlike many portable headphone amplifiers that convert 3.5mm Unbalanced signals to 4.4mm Balanced signals or lack support for a 4.4mm Balanced connection altogether, the AK PA10 takes a groundbreaking approach. Most devices compromise the purity of the balanced output during signal transition.

In a unique feat for a portable Class-A amplifier, the AK PA10 proudly features 4.4mm True Balanced input/output, ensuring high output and delivering a vivid audio experience without signal loss during the transition process. Additionally, it caters to a broader range of devices by supporting 3.5mm unbalanced input/output ports.

Experience the true potential of balanced audio with the AK PA10’s innovative design, providing users with flexibility and uncompromised sound quality across various devices.
