More Expandable Options

The AK380 offers great expandable options through its micro USB connection and balanced out ports on the bottom of the unit.

The AK380's functionality is expandable by connecting to a variety of devices. You can increase the output and connect to a greater variety of high-impedance professional headphones through the upcoming AK380 Amp. The AK380 Cradle features balanced output in addition to USB data transfer and charging capabilities, and the AK380 CD-ROM drive rips audio CDs directly to 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 (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.

* The PEQ supports up to 8 kHz – 192 kHz (8/16/24-bit) formats, but DSD and 32-bit audio are not supported.

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.

If on the same access point (AP) network, music files on a PC or NAS can be played back via DLNA.

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.
