Let op: nog slechts 1 st. demo AK320 verkrijgbaar!
Astell & Kern AK320, de nieuwe highend portable mediaspeler, qua performance net onder de AK380, met een milder prijskaartje.
Met als referentie, de onlangs geintroduceerde AK380 (3.999€) heeft A&K een nieuwe portable mediaspeler, de AK320 uitgebracht. Uitgevoerd met dezelfde DACs als de AK380 (AK4490 dual dacs), DSD naar PCM afspeelmogelijkheid, 20 bands eq, Femto Second Clock, DLNA based en en metalen touch home sensor gaat nu bereikbaar worden voor een grotere groep gebruikers.
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.
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, ±0.1 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).
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 AK320 is able to create a more accurate frequency value and make fine jitter corrections.
As a result, the AK320 faithfully reproduces analog sound closer than ever to the original source when transmitting a digital signal as an analog signal.
The AK320 supports USB DAC functionality.
The AK320 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 Dual-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
