Product description


The Starting Point of Music,AK Jr

Thin and Light
The AK Jr project gives everyone the opportunity to comfortably listen to high resolution audio,anytime and anywhere. Although the Astell&Kern was a portable device, its relatively large size made it less convenient for some. The AK Jr’s compact design delivers the highest sound quality while fitting comfortably in your pocket. The AK Jr is like carrying a small concert in your pocket.

Design Story
The AK Jr simplifies complex features of Hi-Fi audio to a smartphone-like experience. The simplified design exemplifies the original concept of the AK Jr. The raised screen provides secure grip and slims down the profile from 8.9mm to 6.9mm.

Increased output and lowered impedance
The AK Jr's output level of 1.95 VRMS represents a 14% increase over the AK100's 1.5 VRMS. Our engineers have reduced the output impedance to 2 Ohms for a significant gain in sound fidelity from the AK100’s 22 Ohms. As the AK Jr supports many various types of earphones and headphones, a separate amplifier is unnecessary.

The AK Jr supports DSD,the digital audio format widely considered to be the next-generation in high resolution audio. Listen to a greater range of audio through DSD.

The AK Jr can also function as an external DAC (sound card) when connected to a PC or Mac via USB. When playing music stored on a computer,the AK Jr delivers the same high level of audio quality while eliminating the need for a built-in sound card. - The AK Jr's EQ settings are disabled when used as a USB DAC. The USB DAC feature also supports UAC 1.0 (USB Audio Class 1.0 / 24-bit, 96 kHz) audio output.

Full Touch Screen
The AK Jr features a 3.1" LCD touchscreen . The smartphone-like full touch capabilities offer responsive interface and the larger screen displays more information.
