Details & Highlights

Product Highlights

    The AK300 Hi–Res Music Player puts FLAC audio in the palm of your hand as the latest evolution of the famous AK series portable high–resolution audio players. Pressure–sensitive metal capacitive touch interface and a 4” WVGA touchscreen enables smartphone–like touch capabilities with a responsive interface for an improved user experience including the appearance of album covers. Built–in Bluetooth and Wi–Fi connectivity allows the AK300 to wirelessly connect to speakers and sound systems for listening out loud. With more features than ever before, the 64GB AK300 doesn’t skimp when it comes to your FLAC (Free Lossless Audio Coded) and ALAC (Apple Lossless Audio Codec) files. Like carrying a concert in your pocket, the AK300 is thin, light, and simplifies complex Hi–Fi audio features into a smartphone–like experience with a raised screen for a more secure grip, a full aluminum body with textured volume wheel, and increased output with lowered impedance. Carry even more music with the additional 128GB microSD memory card for a grand total of 192GB of storage capacity, holding approximately 1,875 hi–res audio files. The AK300 supports DSD (Direct–Stream Digital) files with pulse–density modulation encoding and functions as an external DAC (Digital to Analog Converter) when connected to a PC or Mac USB port, bypassing your computer’s internal soundcard to deliver the same high–quality audio you enjoy.

    Enjoying Music

    While succeeding the state–of–the–art DAC and scalability as applied to the AK380 and AK320, the latest model has improved accessibility by being priced at a reasonable level.

    AK300 is capable of bit–to–bit playback up to 24bit, 192kHz.

    32bit audio is downsampled using a sample–rate converter (SRC). In addition, DSD 64/128 can be played back via conversion to PCM.

    PEQ (Parametric EQ)

    A parametric equalizer (PEQ*1) was implemented in the AK380 to deliver detailed adjustment of the original sound, and an audio digital signal processor (DSP) was added to aid in this process. 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.

    What is Parametric Equalization?

    Parametric equalization refers to the ability to increase or decrease the volume within the Q value range. A Q value is a frequency range relative to a selected frequency. The frequency range decreases when the Q value increases and vice versa.

    What is Graphic Equalization?

    Graphic equalization divides the audible frequency register into several registers and increases or decreases the level of each register with a volume slider to adjust the respective frequency's characteristics. The switches of the volume slider are connected like a graph to visually determine the frequency characteristics, hence the name "graphic equalizer."

    Equipped With a Femto Clock to Deliver True Original Sound

    AstellKern implemented a voltage–controlled crystal oscillator (VCXO) high–precision clock with a reference jitter value of 200 femto seconds*3. 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).

    What is VCXO?

    A VCXO, or a voltage–controlled crystal oscillator, is a type of crystal oscillation device that creates oscillation frequencies. External environmental stimuli, which in this case mean voltage inputs, influence the frequency value. Adjustments to the voltage input tunes a precise frequency value.

    What is Jitter?

    Jitter refers to the undesired deviation in time that occurs in a periodic signal. In this case, jitter is the error that occurs in the reference clock required to perform the sampling in digital audio equipment. 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 supports USB DAC functionality.

    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.

    AK Connect App

    AstellKern has further enhanced DLNA functionality via the AK Connect app. 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.

    Pressure–sensitive Metal Capacitive Touch

    The AK300 features the same metal touch interface as the AK380 and AK320. The Metal Touch functions as a home key and interfaces with the device via pressure–sensitive touches.

    More Expandable Options

    The AK300 can be expanded to a variety of devices through the micro–USB and balanced audio out ports located at the bottom of the product. It can be connected with the AMP as well as professional high–impedance headphones for high output and USB for data transfer and charging. It can also be connected to the Cradle for balanced audio functionality as well as the CD–RIPPER to conveniently rip audio CDs.
