A blend of ‘Environment’ and ‘Tune,’ EnviroTune is an intelligent sound-tuning technology that analyzes
listening surroundings in real time to restore musical details easily lost to ambient noise.
The built-in microphone detects changes in ambient noise in real time, analyzing input sound by frequency
band to automatically compensate for frequencies masked by noise.
Without unnecessarily raising the volume, the sound continuously adapts to your environment—allowing
complete immersion in the original detail of your music, anywhere, anytime.
The PD5 drastically improves group delay—a chronic issue in audio systems—through proprietary ESA
(Enhanced Signal Alignment) technology.
By aligning frequency signals to arrive with greater uniformity,
ESA
minimizes frequency distortion and elevates sound quality to be clearer and more pristine.

*What is Group Delay?
It refers to the time difference required for various frequencies to pass through an audio system, causing
sound signals across different frequencies to arrive at slightly different times rather than simultaneously.
To deliver the ultimate DAP experience like never before, we incorporated the latest DACs and upgraded
specifications, while further advancing TERATON ALPHA—Astell&Kern’s Ultimate Sound Solution.
Perfected through relentless research, TERATON ALPHA is Astell&Kern’s proprietary audio technology
designed to deliver sound closest to the original source through effective power noise removal,
efficient power consumption, unwavering amplification, and a seamlessly converted audio output
interface.
The PD5 features Digital Audio Remaster (DAR) technology, developed to deliver the refined sound of
higher sample rates.
DAR upsamples the sample rate of played audio tracks to transcend the physical
limitations of the original source format. Higher sample rates enable more delicate and precise
playback,
bringing sound closer to true analog expression.
It vividly reproduces original recordings, allowing
you
to experience subtle musical nuances and rich sound at an elevated level.
Select from four distinct DAC filters to tailor your personal listening preference.
Take full control of your sound characteristics with custom signal shaping.
Crossfeed blends a portion of the original signal from one channel and sends it to the opposite channel with a slight time delay, centering the soundstage. This recreates the natural spatial presentation of listening through loudspeakers while reducing ear fatigue during extended listening. Tailor the sound to your preference with detailed settings including Shelf Cutoff, Shelf Gain, and Mixer Level.
ReplayGain automatically normalizes track volumes across different music files, ensuring a consistent
playback level throughout your playlist without manual adjustments.
* ReplayGain supports audio tracks up to 24-bit/192kHz.
Equipped with Dual-Band Wi-Fi (2.4/5GHz), the device provides enhanced network performance for seamless high-resolution music streaming and Roon Ready integration.
