Description

The Astell & Kern AK Jr simplifies complex features of Hi-Fi audio to a smartphone-like experience. The simplified design exemplifies the original concept of the Astell & Kern AK Jr. The raised screen provides secure grip and slims down the profile from 8.9mm to 6.9mm. The full aluminum body and textured aluminum volume wheel allows smooth one-handed operation.

 

Increased output and lowered impedance
The Astell & Kern 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 Astell & Kern AK100’s 22 Ohms.
As the Astell & Kern AK Jr supports many various types of earphones and headphones, a separate amplifier is unnecessary.

 

DSD to PCM
The Astell & Kern 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 Astell & Kern AK Jr converts 2.8 MHz DSD files to PCM.

 

USB DAC
The Astell & Kern 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 Astell & Kern  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 Astell & Kern AK Jr features a 3.1″ LCD touchscreen that is about 1.4 times larger than the AK100’s LCD. The smartphone-like full touch capabilities offer responsive interface and the larger screen displays more information.
Album covers that are in a 4:3 format on the Astell & Kern AK100 are now displayed 1:1 aspect on the Astell & Kern AK Jr’s larger screen.
