Key Features
Dual DAC module with audio sampling
The A&futura SE180 digital audio player allows music fans to customise their sound with different audio-flavoured DAC modules to find the hi-fi-grade sonics that suit.
Shape your sound
Following the SEM2 and SEM3, the SEM4 Asahi Kasei AK4493SEQ dual DAC is the latest in a series of optional modules available for the A&futura SE180 digital audio player. This DAC possesses the ability to play high resolution audio files up to 32-bit/768kHz PCM and native DSD512, so music fans can enjoy studio-grade sounds as the artist intended.
Introducing Digital Audio Remaster (DAR)
Specially developed for the SEM4, DAR upsamples the sound source up to a maximum PCM sample rate of 384 kHz/DSD256. Whatever file you are playing, the SEM4 will convert to a higher sample rate that suits the source. The result will be a more refined and richer sonic performance, revealing detail and nuances in your favourite music otherwise unheard.
DAC with Velvet Sound
The SEM4 is the first Astell&Kern product to be equipped with a premium dual AK4493SEQ DAC from Asahi Kasei. Featuring VELVET SOUND™ technology, this DAC aims to deliver a more natural audio with even lower noise and distortion, along with a wider dynamic range. Carefully selected advanced switch and capacitor components allows the low-power consumption design to provide a stunning low-noise playback performance of up to 14 hours - the longest among SE180 modules.
Hand-pick your headphone
The SEM4 DAC module supports 2.5mm, 3.5mm and 4.4mm headphones connections for accommodating and driving a greater variety of headphones and in-ear monitors (IEM).
