The Starting Point of Music, AK Jr

Thin and Light

The AK Jr gives everyone the opportunity to comfortably listen to high resolution audio, anytime and anywhere. The AK Jr’s compact design delivers the highest sound quality while fitting comfortably in your pocket. It's 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. The full aluminum body and textured aluminum volume wheel allows smooth one-handed operation.

Increased output and lowered impedance

What are we talking about here? Simply put, the AK Jr supports many various types of earphones and headphones, a separate amplifier is unnecessary.

DSD to PCM

The AK Jr supports DSD, the digital audio format widely considered to be the next-generation in high resolution audio. DSD is converted to PCM allowing you to listen to a greater range of audio.


USB DAC

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.

Note: 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 screen has full touch capabilities, offers a responsive interface and the large screen displays more information than previous models of our players.


64GB + 256GB* microSD (*largest card size available)

The AK Jr features 64GB of internal memory and supports microSD cards up to 256GB, to store more music than ever before. The AK Jr is capable of offering a whopping total storage capacity of 320GB! The combined 320GB of internal memory and external microSD card capacity is capable of holding more than 3,000 high resolution audio files. (Based on one, 4-minute song @ 24 bit/96 kHz, taking up 90MB) 

Accessories

A great addition for the AK Jr is a AK Jr case! Made from LASKINA® polyurethane fabric by Synt3, a world-class manufacturer of polyurethane located in Milan, Italy. Available in 6 different colors and 2 types of materials. Check them out here!

    tim: The AK Jr does not transmit audio through the USB port. However, you will be able to connect to the USB port of your car, choose the “Connect as removable disk” option, and control the music stored on the AK Jr through your car’s stereo. However, you will be using the AK Jr as a transport at this point and sound processing is done through your car’s stereo and not through the AK Jr’s DAC and sound processor.

    Can thi splay the music thru the USB so I can control it with my car stero?

  • Astell&Kern Online Store

    Mark: The AK Jr is not an Apple product so it will not interface directly with iTunes. However, you can transfer music to the AK Jr with the drag and drop method. Please note it will not support the .M4P format or any copyright protected file. The AK Jr does not support Tidal, as it does not have support for Wi-Fi.

  • Mark

    Two questions:
    Can I play/transfer my iTunes music?
    WiFi to play my Tidal music?

  • Astell&Kern Online Store

    Lionel: Yes, it is compatible with Macintosh computers running OS X version 10.7 and above. It also supports AAC, ALAC (M4A), and AIFF format audio files.

  • Lionel

    Is the AK jr compatible with iMac and will it play apple lossless files?

  • Astell&Kern Online Store

    Mark: the AK Jr does not require any software to transfer music, as it is a drag and drop operation. Please make sure that your music files have the proper ID tags written so that is can be displayed properly. You may also want to initiate a library scan of your music files by navigating to Settings – Auto Library Scan – Library Scan so that it can properly index the music into Song title/Album/Artist/Genre.

    genuino: The USB DAC feature is currently unsupported with 64bit computers using a USB 3.0 port. Please use a USB 2.0 port in order for the USB DAC feature to work.

    David: No problem! If you have any further questions, please contact us at: support.inc@iriver.com.

    Is there a recommended software that you can use to sync your music library to the AK-Jr. I tried using Windows Media Player but the music is only copied, there is nothing in artists, songs, genres albums or playlists :)
