SINGAPORE, @mcgallen #microwireinfo, February 10, 2022 – Astell&Kern, the world leader in high-end high-resolution audio devices, has redefined the headphone amplifier with the introduction of the ACRO CA1000.

Headphone amplifier

To realize any hidden potential and power the most sophisticated and power-hungry headphones, a dedicated amplifier is essential. The ACRO CA1000 supports a four-step gain level adjustment that can drive high-impedance headphones with an output level of 15 Vrms (no-load condition) – without sound quality deterioration.

Equipped with balanced 2.5mm and 4.4mm and unbalanced 3.5mm and 6.35mm outputs, the ACRO CA1000 can accommodate a wide variety of headphones. By using ultra-small relay parts, the circuits of each output are physically separated from each other to minimize any internal noise interference that can adversely affect signal and sound quality.

DAC magic

A digital-to-analog converter (DAC) primarily contributes to the closeness to the original recording that the listener will feel. With a design and engineering pedigree of award-winning premium DAPs, Astell&Kern’s knowledge of DAC technology is unparalleled. The ACRO CA1000 comes with a high-quality, high-performance Quad ES9068AS DAC that delivers clear, detailed and balanced sound without distortion. The Quad-DAC also supports Hi-Res Audio playback up to native DSD512 and 32-bit/384kHz, allowing the music fan to get even closer to original studio sound, while revealing musical detail never before seen. heard before.

The result of extensive research and development, this sound solution is designed to deliver audio playback close to the original sound through the audio output interface using effective power noise suppression, efficient noise management power and amplification with minimal distortion.

The speaker effect with headphones

In a headphone environment where the left and right channels are clearly separated, ear fatigue may increase during prolonged listening.

This mode has the effect of blending the left and right channels, relieving ear fatigue by creating a more natural sound close to listening through the speakers. In this setting, Shelf Cutoff, Shelf Gain and Mixer Levels are adjustable to suit listening tastes.

DAP identifiers

A 4.1-inch tilting touchscreen (up to 60 degrees) allows for easy control of player and amp settings with an intuitive Android operating system and feature set taken from its award-winning portable DAPs.

Although not fully mobile like an Astell&Kern DAP, this hybrid amp player system is compact and portable. Equipped with a large capacity 8400mAh battery, the ACRO CA1000 can provide up to 10.5 hours of playtime without a separate power supply. As the CA1000 supports USB-PD 2.0 (9V/3A), anyone with a fast charger that supports USB Power Delivery (USB PD) can benefit from fast charging. – a one hour charge provides 50% of the battery, while it takes 2.5 hours for a full charge.
