High-Resolution Digital Music Player: Astell & Kern's experience with
technology and portable devices makes it possible for the KANN to offer dynamic
power and performance. KANN is the complete all-around portable high-resolution
digital music player with powerful output and studio quality sound. In
addition to a high-resolution digital music player, the Astell & Kern KANN can be
used an external USB DAC.
AK4490 Single DAC: The Astell & Kern KANN is equipped with a
AK4490 Single DAC (digital-to-analog converter) for 32-bit/382kHz PCM audio
playback and native DSD playback up to 11.2mHz.
Femto Clock: The Astell & Kern KANN uses a
voltage-controlled crystal oscillator (VCXO) high-precision clock with a
reference jitter value of 200 femtoseconds. Femto clocks are typically used in
high-end audio components. The clock is measured in femtosecond units (one
quadrillionth of a second -- or 1/1000 trillion) which allows the device to
create a more accurate frequency value and make fine jitter corrections. Typical
clock jitter in the KANN is measured at 30 picoseconds (or 30/1-trillionth).
Built-in Memory + External Storage: The KANN has a built-in
64GB internal flash memory for downloading and storing you digital music files.
You can also insert a microSD card (up to 256GB) and full-size SD card (up to
512GB) in the memory card slots on the bottom of the device for additional storage
capacity (up to 768GB), for a total maximum storage capacity of 832GB. The
memory cards should be formatted in FAT32.
Media File Transfer: You can download digital music files
from your Windows PC or Mac computer to the Astell & Kern KANN through its
USB-C USB port and the included USB-C to USB cable.
- Supported Audio Formats: The KANN is capable of
download and playback of high resolution digital music files up to
32-bit/382kHz; including FLAC, WAV, ALAC, and AIFF. It also supports
playback of DSD music files up to 11.2mHz. In addition, the KANN will
support highly compressed music files such as MP3, WMA, AAC, OGG, and APE.
- Computer Requirements: The KANN is compatible with
Windows 7, 8, or 10 (32-bit or 64-bit versions of each). It also support Mac
OS X 10.7 and up. Mac users need to download and install the MTP program
from the Astell&Kern website.
USB DAC: The USB DAC functionality allows the KANN to be
recognized as a sound card on a computer. The KANN's micro-B USB port is connected to a free USB
port on your Windows PC or Mac computer (cable not included); the music from your computer is then
played through the KANN's earphones port for an enhanced listening experience.
This USB DAC connection bypasses the inferior soundcard of your computer or
laptop and uses the KANN as the USB DAC for better sound quality. It supports
playback of PCM (8-384kHz; 8/16/24/32-bit) and DSD (2.8/5.6/11.2MHz) high
resolution music files, providing much richer sound through superior ambience
and resolution way beyond the limits of the embedded soundcard of your computer.
- Computer Requirements: Compatible with Windows PC and
- Windows PC: XP (32/64-bit), 7 (32/64-bit), 8
(32/64-bit), and 10 (32/64-bit)
- Mac OS: OS X 10.7 (Lion) or later
- Supported Music Files:
- PCM: sampling rate of 8-384kHz; bit depth of 8, 16,
24, or 32-bit
- DSD: sampling rate of 2.8, 5.6, 11.2MHz; bit depth
Notes: When using the KANN as a USB DAC, its PEQ settings
are not applied.
Balanced & Unbalanced Output: The Astell & Kern KANN is
outfitted with a 2.5mm balanced headphone output (L+/L-/R+/R-) and a 3.5mm
unbalanced headphone output (L+/R+/GND) for connection with a variety of
- 2.5mm Balanced Jack: The KANN features a 2.5-mm/4-pole
balanced output for connection with compatible balanced
earphones & headphones. This type of connection requires that you connect
your compatible headphones to both the unbalanced port (ground) and balanced
audio port (L/R) of the KANN. Unlike the unbalanced type, the balanced
output type is capable of removing noise (common mode noise) that can occur
in "signal + inverting amplifier signal" and has the strength of increasing
output due to its double transmitting signals.
- 3.5mm Unbalanced Jack: The KANN also features a
3.5-mm/3-pole unbalanced output that offers compatibility with a
variety of HiFi earphones and headphones. The 3.5mm headphone jack doubles
as an mini optical digital output with a fixed volume level.
Built-In WiFi: The KANN features built-in 2.4GHz WiFi
(802.11 b/g/n) which allows you to connect to your home's WiFi network
wirelessly with support for AK Connect & DLNA.
- AK Connect: The KANN comes equipped with the AK
Connect feature that can be connected with network-ready Astell & Kern
devices and speakers (sold separately). It will wirelessly output its sound
through Astell & Kern speakers (sold separately).
- DLNA Compliant: It is also appointed with wireless
networking DLNA (Ver. 1.0), which makes it easy to work with NAS/PC on the
same network and through an AK Connect app on your
Apple iOS 7.1+ or
Android OS 3.0 device. The KANN can access and play back music files
stored on a computer on the same wireless network.
Note: Firmware/software updates are done over the KANN's
WiFi network connection.
Bluetooth Transmitter: The KANN has built-in Bluetooth 4.0
for connecting a Bluetooth speaker, headphone, or receiver so you can listen to
your digital music files wirelessly. In addition to support for the standard
Bluetooth SBC codec, the KANN offers support for aptX allowing CD quality
(16-bit/44.1kHz) wireless audio playback for Bluetooth speakers, headphones, and
receivers that also support aptX.
Note: DSD playback is not available via Bluetooth, and
performance may be limited for high-res playback; 48 kHz or lower resolution
is recommended). Car audio Bluetooth connections are not supported.
USB Audio Out: The KANN can be connected to the USB audio
input of an AV receiver or integrated amplifier using an OTG cable (sold
separately). The KANN can output PCM music files to your receiver or amp. It
can also transfer DSD in native through DoP, or convert DSD into PCM for output
to amplifiers that do not support DoP.
User Interface: The Astell & Kern KANN features a
high-quality user interface to make it easy to find and select your music files,
change the volume, and adjust the sound:
- 4" LCD Touchscreen: The full-color 4" LCD touchscreen
has a resolution of 480 x 800 pixels. The screen displays the title and
artist of the currently playing song, along with elapsed and remaining time,
with the album art in the background. You can make adjustments to the EQ, set the repeat and random modes, and add
the song to a playlist, all using the touchscreen interface.
- Rotary Wheel: The KANN has a side-mounted rotary wheel

buttons on the player (four on the front-panel and one on the top). The
top-panel button is for power. The four front-panel buttons include
Home/Menu, Play/Pause, Skip Forward, and Skip Backward.
20-band Parametric EQ: The KANN features a parametric EQ and
an audio DSP to allow you to make detailed adjustments in the original sound to
suit your tastes. The DSP takes the existing 10-band graphic equalizer found in
the KANN with ±0.5dB adjustments and upgrades it to a 20-band EQ with ±0.1dB
adjustments, plus variable gain and Q values. You can set the EQ curve by simply
"drawing" the curve on the touchscreen. The EQ frequency bands include: 30Hz,
45Hz, 60Hz, 90Hz, 120Hz, 180Hz, 250Hz, 380Hz, 500Hz, 750Hz, 1kHz, 1.5kHz, 2kHz,
3kHz, 4kHz, 6kHz, 8kHz, 12kHz, 14kHz, and 18kHz. You can adjust the gain from
-5dB to +5dB in 0.1dB increments, and the Q from 0.1 to 4.0dB in 0.1dB
increments. If you choose not to activate the Parametric EQ, you can use the Pro
EQ presets recommended by professionals.
Gapless Playback: Gapless Playback allows you to play the
next song without any interruptions or silence. Gapless playback is only
supported between two audio files with identical bit rates, sample rates, and
Power Requirements: The KANN is equipped with a rechargeable
Lithium-Polymer battery (6200mAh/3.7V). The battery charges via USB in about 8
hours using a USB port on your computer or about 4 hours using a USB/AC power
adapter (sold separately). A 39" USB-C to USB cable is included to connect
the player to your charging device. A fully charged battery can provide up to
approximately 15 hours of continuous playback time.
Note: The maximum 15-hour continuous play is based on 16-bit/44
kHz, FLAC file format, screen off, 50% of volume, and Normal playback.
Extruded Aluminum Construction: The design of the KANN
stands apart from Astell&Kern's other product lines. During assembly, the parts
are slid into the aluminum extruded body, and the unique, no-joint design
delivers a durable yet sleek appearance. A protective film is included to
protect the LCD touchscreen.
Optional CD Ripper (Sold Separately): The KANN can be expanded to
a variety of devices through the Micro-B USB and balanced audio out ports located
at the bottom of the player. It can be connected to Astell & Kern's CD-RIPPER to conveniently rip audio CD
(all devices sold separately).
