Complete Separation of Digital and Analog Signals in a HEXA Structure

Tthe SP3000M id equipped with the same innovative Hexa audio circuit design first found in the SP3000, that has four of AKM’s flagship AK4499EX DACs and two separate AK4191EQ chips that handle digital signals. Thanks to this technology, you can enjoy amazingly vivid sounds only Astell&Kern can create. Most digital players process digital and analog signals together inside the DAC. However, the SP3000’s advanced HEXA structure reduces the noise of the digital signal input through the AK4191EQ, a separate digital delta-sigma modulator, and the AK4499EX DAC is then designed to process the analog signals separately. With such an unparalleled design, SP3000M physically separates digital and analog signals, completely boasting the perfect A&ultima sounds through the unmatched 130 dB SNR, equal to the SP3000, despite its much smaller size.

Silver Plated Shield Can

A shield can is applied to prevent various noise and electromagnetic interference from affecting the audio block. The SP3000M takes it a step further to achieve excellent audio performance and perfect shielding by applying highly conductive, high-purity silver on the existing shield can, and physically separating digital and analog signals.

Stunning Audio Performance with Independent Dual Audio Circuits

In order to create a truly innovative DAP, not just a great DAP, A&K tried to overcome the limitations of sound by envisioning an independent dual audio circuit that has never been attempted by anyone featuring a HEXA structure with unbalanced and balanced outputs. Almost all other DAPs, including Astell&Kern, use an internal DAC for both unbalanced and balanced outputs. Since the signal from the DAC is divided into unbalanced and balanced then delivered to the AMP, an Audio Switch is essential. However, when using a switch, there is a limit to the range that can receive the signal sent by the DAC, so most DAPs reduce the signal size first and then when the signal is transmitted back to the amplifier, it is necessary to restore the original signal size. This causes a limitation in improving the audio performance. To overcome the limitations, the engineers designed a HEXA structure using two AK4191EQs and four AK4499EXs, creating an innovative unbalanced and balanced independent dual audio circuit design. As a result, the SP3000M achieves a SNR of 130dB, the best of any DAP available. You can feel the clean, pure delicacy of sound with the SP3000M that you cannot not experience in any other DAP.

TERATON ALPHA – The Essence of A&K Audio Technologies Merged Into the SP3000M

In order to develop the ultimate audio player that has never been experienced before, not only do A&K use the latest DAC and technology available, but they use the innovative audio technology of TERATON ALPHA, AK’s Ultimate Sound Solution. TERATON ALPHA, engineered through endless research, is Astell&Kern’s unique technology that has been designed to produce audio playback that is close to the original sound through effective power noise removal, efficient power management and unwavering amplification, and a fully converted audio output interface. HEXA-Audio Circuitry structure and independent dual audio circuit  implemented to the SP3000 was completed with TERATON ALPHA’s sound solution, to create the purest  original sound, and was inherited to the SP3000M.

Drive Your Music, Latest Snapdragon Octa-Core CPU

A&ultima SP3000M is equipped with a Snapdragon 6125 Octa-core processor, so you can enjoy the overwhelming sound, with faster system response and a redesigned generation user interface that moves comfortably and smoothly. Featuring a high-performance CPU and improved 8GB of DDR4 memory, which is twice the amount commonly used in other digital audio players, the more powerful system is stable with fast and fluid movement. The CPU, memory and wireless communication parts are configured as one module, with the digital circuit parts arranged in the same area creating a single system on a chip (SoC). This maximizes the efficiency of the overall circuit configuration by providing more dedicated audio-only circuit space as well as reducing heat and noise from digital circuits.

VU Meter GUI for complete musical immersion

SP3000M comes with a VU Meter GUI, which debuted on the SP3000T and was well-received by consumers for an even more immersive experience. The VU Meter, an iconic piece of audio equipment with a long-standing history, displays voltage levels of voice signals to aid volume measurement and adjustment. Beyond its utilitarian function, the VU Meter’s unique design and retro charm help to enhance the immersive music-listening experience.
