Desciption

Sound in ultra-high resolution from AKM 4493s DAC

To achieve the highest audio quality achievable with a USB DAC, the AK HC4 is the first in the USB DAC Cable lineup to incorporate AKM’s DAC. AKM’s DAC has earned much love when featured in Astell&Kern’s digital audio players, but due to the small size of USB DAC Cables and the challenges of amp design, it has been difficult to implement in the USB DAC Cable lineup until now.

The AK4493s DAC from AKM, used in the AK HC4, is further enhanced with improved noise control, lower power design, and ultra-precise amp design technology, delivering exceptionally high-quality Hi-Fi sound. Furthermore, it supports Native DSD256 and up to 32bit/384kHz to handle any high-quality audio source, allowing you to experience the high-grade sound quality that Astell&Kern delivers.

Precision DAC and AMP design for Hi-Fi Sound

In order to gain stable output power and ultra-high-quality Hi-Fi sound through the Dual Output, AK HC4 introduces an exclusive AMP circuitry that supersedes the standard built-in DAC AMP.

While maintaining a compact form factor 29.5 x 64.5x 14.5mm, we used micro resistors and capacitor parts to achieve a small footprint without compromising performance. Carefully selected ultra-small tantalum capacitors, which are used in AK player products to create a stable system and audio performance by controlling the power fluctuations, are also included to create an optimal audio circuit design. In addition, the output and audio performance are enhanced with Astell&Kern’s unique power management technology to minimize current consumption in respect of the connected device.

3.5mm, 4.4mm Dual Output

The AK HC4 features Dual Output with both 3.5mm and 4.4mm connectors, allowing you to use AK HC4 with most Hi-Fi IEMs and head- phones without the need for adapters or additional cables. The 4.4mm Balanced output provides a high output of 3Vrms, maximizing the performance of sensitive headphones and IEMs, while ensuring clear channel separation and minimal noise. The 3.5mm Unbalanced output is compatible with the majority of existing IEMs and headphones, offering a sufficient output of 2Vrms to fully experience the capabilities of your IEMs.

Digital Audio Remaster Technology for Even More Vivid Original Sound

The AK HC4 is equipped with digital audio remaster (DAR) technology, which was only applicable to the latest digital audio players from Astell&Kern.

DAR technology is developed to upsample the sample rate of the sound source being played to go beyond the limits of the source format. The high sample rate allows more refined play and offers delicate and analog-like original sound, helping you to enjoy the richness of the original sound, subtle differences in the nuance of the music and rich sounds at a higher level. In addition, the DAR slide key on the side of the product gives you a more intuitive selection of DAR options.
