Highest Output Power AK Player Four Stage Amplification Unleash All Potential

Headphones generally have higher requirements for output power, and the headphone unit configuration in the market is constantly being updated, and more different hybrid unit structures are adopted, so that the headphone requires a player with higher output power to fully exert its performance. Because of this, in response to market needs, ACRO CA1000 is equipped with a new independent amplifier, which provides four levels of output power for users to choose from. The maximum output power "Super Gain" reaches 15Vrms, allowing users to fully liberate the potential of the headset and enjoy high reproduction at the same time. perfect sound quality with extremely low distortion.

In addition to super output power, ACRO CA1000 is also equipped with a variety of different terminals to meet the different needs of users, such as 6.35mm and 3.5mm single-ended output commonly used in general headphones, and 2.5mm and 4.4mm balanced output. There are RCA input/output, coaxial input (COAX In) and optical input (Optical In) options, so that the CA1000 can be easily used as a portable player or a member of home desktop and audio systems. In order to minimize the noise floor and interference in the sound, Astell&Kern also specially separate the USB-C plug for charging and the USB-C plug for data/audio transmission (Data/Audio) at the rear of the fuselage, which greatly reduces the fuselage. The interference and noise floor caused by the current when using USB-C as the input achieves a truly pure and unblemished sound enjoyment.

Flagship-level decoding configuration to reproduce perfect sound quality
ACRO CA1000 uses the same four ESS Technology ES9068AS Quad-DAC decoding as the flagship player A&ultima SP2000T, low power consumption and different amplifier circuits can also be retracted and placed freely. It has greater flexibility and plasticity in power supply management of the player. Make the sound cleaner and purer. ES9068AS supports MQA Full Decoder decoding performance, and also supports up to 32Bit/384kHz and DSD512/22.4MHz file formats. Users can liberate all details in music when using HD streaming platforms such as Tidal, greatly improving convenience and maintaining high-resolution. sound quality. The Quad DAC decoding architecture enables the CA1000 to achieve a more detailed and deeper sound performance in sound, and the sound is more three-dimensional and realistic, making the overall sound field and space more complete and realistic, retaining the Astell&Kern high-reduction tuning style .

Patented tuning to isolate the noise floor from the source
After being used for the first time on the SE180, it has been recognized by the market. TERATON ALPHA has created its own patented tuning technology for Astell&Kern after years of research and combined with the player's long-term tuning experience. In order to further improve the sound quality and noise floor control, Astell&Kern also added the patent to the ACRO CA1000. TERATON ALPHA achieves the most careful and precise control in the power supply, signal source, circuit and amplifier design, so that the player can achieve the most efficient power output performance, which not only effectively reduces noise and noise in the sound, but also greatly improves playback. The music reproduction degree of the instrument is improved, so that the sound becomes more detailed and real, and it satisfies the pursuit of the ultimate sound quality by the enthusiasts.

Ad hoc Crossfeed function
Realize a natural two-channel sound field on traditional headphones. Since the left and right channels of music are played independently on both sides, it is easy to cause hearing fatigue for users after long-term use, especially on headphone systems. This results in an unnatural feeling on the sound field. In order to allow users to experience the most realistic and restored sound field and listening experience, Astell&Kern added Crossfeed to ACRO CA1000. By mixing the left and right channel signals with the adjusted frequency band on the acoustic circuit of the earphones, it is possible to achieve a dual The state of stereo playback allows users to experience a wide natural sound field that is difficult to achieve with traditional headphones, and maintains a comfortable listening experience after long-term use. Users can adjust Shelf Cutoff, Shelf Gain and Mixer Level by themselves on the Crossfeed interface, and carefully adjust according to various earphone matching and personal preferences, and choose the most matching and comfortable tone.

Designed from the user's point of view to achieve home portability in one
Although the CA1000 is designed for the needs of headphone users, it still retains the shadow of a portable player in the body design, so that users can convert the CA1000 from a desktop system to a daily attendance partner at any time. The fuselage is equipped with a 4.1-inch touch screen, which can be adjusted to different angles according to the user's needs. The maximum viewing angle can be adjusted upwards up to 60 degrees. Users can easily operate and change songs while enjoying music at the desk. The CA1000 also uses the same operating system as other players.

In addition, the CA1000 also supports the AK File Drop function. Users only need to connect a smartphone, computer or personal FTP file system to the same network to wirelessly transfer music files from their personal devices to the u-body memory. More efficiency in music file management. The CA1000 also supports the BT Connect function. Users only need to connect the player to the audio source device to play in wireless streaming mode.
