TERATON ALPHA Technology

• Great headphone amplifiers generate true and pure sound reproduction not only a stable output is realized but also each and every part from power, noise, signal transition, circuit structures, etc., are carefully designed and implemented.
• AK PA10 is small enough to be portable but operates seamlessly with a wide variety of headphones and IEMs, and is enhanced with the addition of TERATON ALPHA technology which is an AK Ultimate Sound Solution allowing for playback of ultrahigh-quality sound without any distortion.
• TERATON ALPHA, engineered through many years of endless research, is Astell & Kern's unique technology that has been designed to produce audio playback that is close to the original sound, through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface.

Distortion-Free Analog Sound of Class-A Amplifier

• Class-A amplifiers offer the best linear output, providing soft, warm, and natural sounds by amplifying signals without distortions or defects. This characteristic makes it the most sought-after amplification method by music lovers, though it is considered impossible for portable audio devices as it requires high power consumption and design that is difficult to be realized for small devices.
• AK PA10 integrates a Class-A amplifier based on the unique circuit design technology of Astell & Kern, offering signature analog sounds.
• With a unique circuit design from Astell & Kern that reduces power consumption and increases output while removing noise, AK PA10 is specifically designed to deliver the amazing sounds of a Class-A amplifier anywhere and at any time.

Class-A Current Control

• Controls current to suit different headphones and IEMs reproducing a more intensive and spatial sound.
• Offers a three-stage control of Class-A AMP current, emphasizing the characteristic of Class-A AMP relative to the current value and creating a more intense sound.
• Helps with power consumption for battery-powered portable devices
• Create sounds that suit the characteristics of headphones and IEMs through the three-stage current control option
• Generates a textured and spatial sound

Vivid Sound Output

• Sufficient amplifier output is required to extract all the subtle nuances in music when played back through varying headphones and IEMs.
• When connected to the balanced input, the AK PA10 can support up to 6.2 Vrms output at high gain.
• Choose the gain level that offers the best sound of the headphone and IEM that you use to enjoy crystal-clear sounds
• Brings out the full potential that your audio device has to offer

4.4mm In/Out True Balanced Circuit Design

• Supports 4.4mm True Balanced input/output for high output and vivid audio
• Supports 3.5mm unbalanced input/output ports, so you can use it with a wider variety of devices

AK Analog Sound Anywhere and at Any Time

• Features a built-in 4200mAh battery for 12 hours of continuous playback time without needing to connect it to a power source.
• Enjoy the analog sound of Astell & Kern anywhere and at any time with great portability and class-leading playtime.

Crossfeed Effect from Hardware Circuit

• Crossfeed mixes some of the signals from one channel and sends them to the opposite channel with a slight delay, creating a more central and natural sound, recreating sounds similar to that of listening via a speaker system, subsequently reducing listening fatigue.
• AK PA10's Crossfeed function is implemented exclusively by hardware circuit design, not by digital software, offering a more seamless and sophisticated crossfeed effect without degrading the original sound.

Perfect Circuit Design of High Output and Low Noise

• Incorporates Astell & Kern's signature analog volume control that seamlessly delivers the sounds of the Class-A amplifier.
• Separate power supply IC per audio block that is divided into crossfeed, volume, AMP, etc., so it can comfortably supply the optimal power required for each audio IC.
• Eliminates the interfering ripple noise (that occurs when power is turned on) of DC-DC power, thereby minimizing audio noises that may be amplified along with the audio.
• Proprietary shield technology is applied, so noises and electromagnetic waves do not affect the audio block and the design that physically separates unbalanced and balanced circuits completes the high-output and low-noise audio.

Design

• Slope is the design concept of AK PA10.
• The exterior design shows the identity of Astell & Kern and is designed with an image that portrays powerful performance and a great ergonomic fit in the hand.
• The processed octagonal pillar-shaped aluminum main body is adorned with a diagonally sloping surface.
• The character side presents the design identity of Astell & Kern and prevents slipping of the device. The unibody design that finishes the fit at the rubber pad is attached to the player, allowing for a seamless design that does not reveal the parting lines to the player.
• The delicately processed volume wheel is one unit that is recessed in the body of the product and the control part and volume identification part are separate. This prevents users from unintentionally operating the volume wheel and allows for visually checking the current output level whilst simultaneously controlling the volume.
• The rubber pad on the front allows the audio player and AK PA10 to stay together without movement and vibration when they are bound together with the supplied rubber bands. Additionally, we added a 3D textured pattern that is inspired by the logo of Astell & Kern for a touch of luxury.
• The side switches are indicators to let users know the setting of each function intuitively while adding to the overall robust and distinctive industrial design of the AK PA10.
