The AK240 captured a moment in time at which light had ceased to move, while the AK380 expressed the perpetuity of moving light. Now, the AK300 represents the purity of a shadow as it reflects no light.
The essence of a shadow without being split by light was captured in a restrained yet immaculate shape, and this exemplifies the purity of the original studio sound that only Astell&Kern can deliver.
AK4490's Single DAC-DAC, DSD-to-PCM Playback, Parametric EQ with 20bands 0.01dB, 200 Femto Second VCXO Reference Clock,
Exceptional Expandability, DLNA-based AK Connect App and Metal Touch Sensor Home Button
32bit audio is downsampled using a sample-rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM.
* DSD 64/128 is converted via DSD-to-PCM to PCM 24bit, 176kHz for playback.
This frees up CPU cycles previously needed for calculating graphic equalizers (GEQ), allowing more detailed and accurate calculations via the dedicated DSP.
The audio DSP expands the existing 10-band, ±0.5 dB graphic equalizer (GEQ*2) to 20-band, ±0.01 dB to more precisely adjust the frequency and gain (dB) as well as more accurately specifying the frequency range via Q value adjustments.
Femto clocks are commonly used in high-end audio systems, and the clock is measured in high-precision femtosecond units (one quadrillionth of a second).
By utilizing a femto clock, the AK300 is able to create a more accurate frequency value and make fine jitter corrections.
As a result, the AK300 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal
The AK300 can be connected to a PC or Mac via USB for use as a USB DAC that supports PCM/DSD.
When playing back music stored on a PC or Mac, the Single-DAC is able to deliver richer audio of outstanding soundstage and resolution well beyond the limits of a built-in sound card.
* DSD 64/128 is converted via DSD-to-PCM for playback.
Wireless networking DLNA (version 1.0) connects to a NAS or PC, and is easily controlled with a smartphone or tablet through AK Connect.
Source files on a PC or NAS can be freely transferred and streamed without the hassle of turning on the computer and physically connecting with a cable.
If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA.
Finds a list of content on a media server for selection and playback.
DMC (Digital Media Controller)
Finds a list of content on a media server and establishes a connection to a playback-capable device (renderer). By default, a DMC establishes a connection between a media server and media renderer and controls content playback-related operations.
DMS (Digital Media Server = Network Server)
Actually stores the media content to be shared. When connected to a network, the DMS transmits/distributes the media content for other devices to stream or download.
DMR (Digital Media Renderer = Network Player)
Connects to a media server via media controller for content playback.
The Metal Touch functions as a home key and interfaces with the device via pressure-sensitive touches.
