Compact high-res digital audio player. 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. 32bit 384 kHz Bit to Bit Playback, Native DSD (up to 5.6 MHz) Playback, Parametric EQ with 20bands 0.01 dB, 200 Femto Seconds VCXO Reference Clock, Scalable Amp, DNLA based AK Connect App, Metal Touch Sensor Home Button. 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. 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. 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. 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.
