The Evolution of a Masterpiece, AK380.

Evolved to Serve Pro-Audio>
Astell&Kern has stayed on the course, offering the truest and most natural sound possible. The new AK380 offers the most authentic sound from any digital music format with enhanced features that are sought-after by Pro-Audio. Every bit of the AK380 was designed for Pro-Audio in mind. The sound that Pro-Audio people have been looking for starts with the AK380.

32-bit 384kHz Bit-to-Bit Playback.
All of the AK380’s circuit design including the digital-analog converter (DAC) are ready for 32-bit processing to handle 32-bit music natively. Other products have traditionally used sample rate converter (SRC) method down sampling for playback. However, the AK380 is capable of playing back 32-bit, 384 kHz original sound without any down sampling. The result is the AK380 plays up to 32-bit, 384 kHz, any 24-bit music files, or double layer DSD 5.6MHz natively, without conversion or compression.

PEQ (Parametric EQ)
A parametric equalizer (PEQ1) 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 (GEQ2) 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.

Equipped with a Femto Clock to Deliver True Original Sound.
Astell&Kern 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).

AK Connect App.
Astell&Kern 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 AK380 is the first Astell&Kern product to utilize a metal capacitive touch interface. The pressure-sensitive Metal Touch home button responds to fine pressure changes so users operate the device with just a light touch on the metallic pad.
