About Astell&Kern AK240

The unique design of the Astell&Kern AK240 High Fidelity Audio System is derived from the combination of light and shadow. The front asymmetric look of the unit was designed from the shape of the shadow when light was shining on it. This shape strongly represents the Astell&Kern brand which expresses uniqueness and class while strongly protecting the volume knob as well. There are 2 parts to the design of the volume knob on the AK240. First is the luxurious and exquisite diamond-pattern design on the knob where it is gripped. Second is the fine hairline design at the end of the knob that shines to emphasize the natural beauty of the AK240. The back of the unit is composed of real carbon fiber plates which blend well with the overall AK240 design.

Duralumin
Even though the body of AK240 is just one piece, it goes through 12 stages of production until it is complete. The initial 6 stages involve the original materials being prepared, and the next 6 stages involve putting together all of those original parts.

More Detailed 10-Band 0.5dB-step EQ Setting
More accurate EQ setting is available on the AK240 by doubling the bands (from 5 to 10 bands) and halving the dB steps (from 1dB to 0.5dB) available. One can also create and save customized preset EQ settings to fit various music genres.

Full Touch Screen
Compared to the AK120, the 3.31 inch AMOLED display on the AK240 is about 82% bigger to provide more information at a glance. With the bigger display, the Full Touch screen makes it easy to navigate especially for smart phone users. The playback and volume control buttons have been upgraded on the AK240. Music tracks with long titles, such as a classical music, are displayed on 2 lines for better navigation. Due to the speedy file scanning functionality, a separate DB scanning function is no longer needed and file search is available for easy access to music.

USB DAC
The AK240 supports Native DSD USB DAC function. (DoP method) Through the USB connection, the AK240 can be used as a USB DAC which supports Native DSD playback. The combination of the exclusive DSD chip and the Dual DAC in the AK240 goes above and beyond most computer sound cards and is able to create a greater sense of space and deeper sound while listening to your music.

AK240 Leather Case
The leather case for the AK240 was made from a process called "Full Vegetable Tanning". This special leather material has a lot of oil in it that will allow the leather to shine the more it is used. Many tests and trials have been done with the creation of the leather case in order to highlight the unique design of the AK240.
