SE180 Combines Innovation and fun
            The third product in the A&futura line, the SE180, continues the trend of exciting innovation for
            Astell&Kern products, while providing the uncompromised sound quality Astell&Kern is famous for.
            
            With the SE180, in addition to superb audio technology, we wanted to show users an element of fun that is
            hard to find in most Hi-Fi products. The DNA of innovation found in the A&futura line continues with the
            SE180. It is an advanced audio system created with the technology Astell&Kern is known for around the
            world. With the SE180, premium Hi-Fi Sound is now available through the use of interchangeable, all-in-one
            modules, by Astell&Kern.

    Next Generation Advanced AMP technology
                It is extremely difficult push beyond your previous best.
                
                With the SE180, we applied Next Generation AMP technology to push beyond the sound quality others feel
                is acceptable for Premium Hi-Fi Sound to produce the best sound possible.
                
                From the selection of OP-AMP parts, to circuit design, board layout and tuning, everything has been
                completely redesigned to produce the best sound.
                
                It is difficult to improve the Signal-to-Noise Ratio (SNR) while maintaining a high output.

Interchangeable All-in-one Module
            With the SE180, we wanted to expand on the multi-DAC idea that was first introduced with the SE200.
            
            Like the SE200, different DACs can be used in one DAP, but we wanted to do something different for the
            SE180. The introduction of Interchangeable All-in-One Modules, carry on the multi-DAC experience, but add a
            new and fun experience. This reflects the DNA of the innovation that the A&futura line is known for.
            
            The SE180 is a module-separated product that increases the convenience of connection between the main body
            of the player and the module. It features an innovative double-locking design that securely connects each
            component while providing smooth lines that naturally flow without any sense of separateness between the two
            pieces.
            
            By applying different DAC/AMP configurations, adjusting tuning and outputs for each module, the user can
            choose the most suitable module for Premium Hi-Fi Sound. The default configuration module contains the ESS
            ES9038PRO, an 8-channel DAC mainly used for premium home audio equipment.
            
            This DAC provides a wider dynamic range and more detailed sophistication. The module supports 2.5mm, 3.5mm
            and 4.4mm connections to allow for a greater variety of headphones/IEMs.
        
Circuit Separation Structure of Main Body and Module
            By physically separating the main body from the All-in-One module, we completely block power and RF noise
            that may occur from the main body. 
            This creates an independent structure that prevents noise from interfering with music playback.

    Astell&Kern Audio Technology Forms the TERATON ALPHA Sound Solution
                AK ULTIMATE SOUND SOLUTION, TERATON ALPHA
                
                TERATON ALPHA is AK's Ultimate Sound Solution to produce audio playback that is close to the original
                sound through the audio output interface by use of effective power noise removal, efficient power
                management and amplification with minimal distortion.
                
                TERATON ALPHA features Astell&Kern's patented technologies, which are the result of tens of
                thousands of
                hours of continuous research and development to produce sound close to the original sound the artist and
                producer intended.
            
Modules Double Lock for Ease of Use
                The biggest difference between the SE180 and other products that use interchangeable modules is that the
                SE180 uses a double-locking mechanism rather than screws to fasten the module to the body. 
                The first locking structure attaches the module and the body. The second locking structure informs the
                user that the module has been securely fastened to the main body.
                
                The spring supported internal connectors of the main body allow reliable audio signal connection and are
                used to prevent connection failure in case of external shock to the player when on the go.
                
            
            Adoption of Full HD Display forImproved Image Quality
The SE180 features a full HD screen to provide a higher quality display.
- 441 PPI High pixel density
 - 16.7M colors Large color gamut
 - 5.0 inch Large display
 - 1920*1080 High resolution
 
Upgrades to Enhance the User Experience
            
                    To provide more convenient movement through the player user interface that is consistent with an
                    Android smartphone experience, the SE180 features a new navigation bar, the first in an
                    Astell&Kern player.
                    
                    Now you can easily navigate with a single touch and deliver music playback information from any
                    screen. The new one swipe feature moves you to the previous screen.
                
                    The new AK File Drop function in the SE180 makes files transfers easier and more convenient.
                    
                    Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP
                    program located on the same network. Music file management is now possible with a cableless,
                    wireless solution.
                
        Wireless Hi-Fi Sound Through BT Sink
The newly introduced BT Sink function connects the SE180 to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker. Music from an external device, such as a smartphone can now be played back in high-quality on the SE180 using the BT Sink function.

        Real-Time Information Confirmed by Light
The SE180 features a LED volume wheel which displays various playback information, including volume level and bit-rate of the track currently playing.
* LED can be turned on or off according to user setting.
Equipped with Bluetooth 5.0 and Support for Wireless 24-bit aptX-HD, LDAC Codecs
            The latest Bluetooth version provides high sound quality with the convenience of wireless playback to
            headphones and IEMs. 
            Bluetooth 5.0 features faster transmission speed, greater range and a more stable wireless connection when
            compared to Bluetooth 4.2. Both LDAC and aptX HD is supported to provide audiophiles with the best wireless
            sound possible.

DESIGN
            A&futura SE180 is Astell&Kern's first DAC interchangeable DAP, created under the pioneering spirit
            of the A&futura lineup.
            
            The design of the SE180 resembles the traces of the wind left behind as natural and flowing
            lines represent an immersed listening experience of great tunes. A smooth yet expanding
            silhouette is the key design element of the SE180. The continuous and seamless outline of
            the SE180 and almost infinite number of acoustic settings users can create represents the
            infinite possibility of tonal scalability.
The volume knob is located in the center of the curves. It symbolizes the way that various
            tones are gathered and harmonized to emit not only the sound but also light as well. The
            control buttons on the left side have been eliminated and a single multi-function button has
            been added for the convenience of one-handed operation.
            The A&futura SE180’s ceramic rear cover is reminiscent of a finely crafted art
            sculpture. You can feel the quality and craftsmanship devoted to your device through the
            subtle beauty. Gold rings are applied to each audio output port, 2.5mm, 3.5mm and 4.4mm
            connectors, for harmony and unity through its details.
