Overview: The Astell & Kern AK120 from iRiver is a portable high-fidelity audio system, capable of playing Mastering Quality Sound (MQS)--high resolution digital audio from music mastering studios. It has a sleek, brushed aluminum body with a 2.4" touch screen display and an analog rotary volume control on the side. The AK120 has a built-in 64 GB flash memory with dual microSD slots for adding even more memory. The unit is powered by a built-in rechargeable battery, and charges via a Micro USB cable. It comes with a leather case to protect it from scratches
Dual Digital-to-Analog Converters: The AK120 is equipped with two Wolfson WM8740 24-bit, 192kHz DACs, the same as found in some high-end audio equipment (AV receivers). Each DAC delivers outstanding performance with a 113dB signal-to-noise ratio, a super-clean 0.0008% THD+N rate, a -128dB Crosstalk specification for superb left-right separation, and a 10Hz-70kHz Frequency Response at +0.02dB to -0.02dB. One DAC is used for the left channel, and one for the right channel.
External DAC: With Optical In and Optical Out ports, the AK120 can be used as an external optical DAC. You can connect the unit to an optical out port on your computer or CD player to convert your digital music files for listening with headphones, a powered speaker, or through the Auxiliary input of your car or home stereo. You can also use the AK120 as an external USB DAC, connecting the unit via USB from your computer and listen to your stored digital music with headphones, powered speaker, or home stereo.
High Fidelity: The AK120 is capable of playing high resolution digital music up to 24-bit, 192kHz, the same as used in the music mastering process. This Mastering Quality Sound (MQS) includes all of the high resolution formats, including WAV, AIFF, FLAC, and ALAC. These lossless files provide approximately 6-1/2 times more detail than a CD (16-bit, 44kHz), and can be played at sample rates of 8kHz-192kHz and 8/16/24-bits per sample. In addition, the unit can play MP3, AAC, WMA, OGG, and APE compressed audio files.
Built-in and Optional Memory: The Astell & Kern AK120 is equipped with 64 GB of internal memory and dual microSD card slots, that support up to 128 GB each. That gives you a total of 320 GB of storage space that can be used for saving music files. The microSD slots have a sliding cover to help keep dust out.
User Interface: The AK120 features a high-quality user interface to make it easy to find and select your music files, change the volume, and adjust the sound
2.4" LCD Touchscreen: The full-color LCD touchscreen has a resolution of 320 x 240 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. On the touchscreen, you can touch the Play/Pause, Previous/Rewind, or Next/Fast Forward icons to control playback. 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 Volume Knob: The AK120 has a side-mounted analog-style rotary volume knob. The volume control range is 00.0 to 75.0 with detents at every 0.5. As you adjust the volume, the volume range is shown numerically on the display.
- Hardware Control Buttons: There are four physical buttons on the unit: a top-mounted power button, along with side-mounted Play/Pause, Previous/Rewind, and Next/Fast Forward buttons.
Drawing Equalizer: The AK120 has a 5-band Equalizer that lets you set the EQ levels by "drawing" the curve on the touchscreen. You can set the levels of each band from -10dB to +10dB at 62Hz, 250Hz, 1kHz, 4kHz, and 16kHz. Each band can be set one at a time by touching the desired level on the screen, or set them all at once by a single swipe of the finger across the screen in the shape you desire.
Micro USB: The AK120 has a Micro USB port on the bottom of the unit for connecting the unit to your computer for downloading music files and for charging the battery. The AK120 is compatible with Windows XP, Vista, 7 and 8, as well as Mac OS X 10.6.5 and up. You can manage music files using a drag-and-drop method on the software interface.
Power Requirements: The AK120 is equipped with a 2350 mAh 3.7V Lithium-Polymer battery. The battery charges via USB in about 6.5 hours. A fully charged battery can provide up to 14 hours of continuous playback time (Standard--Music: FLAC, 16-bit, 44kHz, Volume at 37, EQ off, and LCD off).
