PERFECTLY DRIVE ANY HEADPHONE/IEM WITH 4 LEVELS OF GAIN AND UP TO 15VRMS OUTPUT
In order to perfectly drive the most sophisticated headphones, a device must be able to fully deliver output that matches the characteristics of the headphone. ACRO CA1000 supports 4 levels of gain settings so that almost any existing headphones can be driven to an optimal state.
The gain setting circuitry implemented in the CA1000 can drive even high-impedance headphones without degrading the sound quality using a max output of 15Vrms.
The ACRO CA1000 unlocks the potential of headphones for a fully immersive experience.
SUPPORTS A WIDE RANGE OF INPUTS/OUTPUTS
ACRO CA1000 features a variety of outputs that can be used by everyone from general users to audiophiles.
3.5mm, 6.35mm Unbalanced, 2.5mm and 4.4mm Balanced output jacks are available to accommodate a variety of headphones/earphones.
The ACRO CA1000 can be used as a Hi-Fi audio system by connecting devices using a variety of digital inputs/output (Optical, Coaxial, Type-C USB) and analog inputs/outputs (RCA). All Input/output settings can be easily and conveniently selected using the CA1000 touch screen.
QUAD-DAC WITH HIGH OUTPUT AND NOISE-FREE SOUND
The ACRO CA1000 is equipped with four ES9068AS DACs, providing perfect decoding capabilities with Astell&Kern's amplifier circuit technology. The clear and overwhelming output expresses the original sound without distortion. 2.5mm, 3.5mm, 4.4mm and 6.35mm output circuits are physically separated by applying tiny, independent relay components.
If the signal from each output stage of a high-power headphone amplifier is not blocked properly, this can cause noise interference. ACRO CA1000 boasts a noise-free output with an independent circuit structure by using relays to completely block connectors that are not in use.
32BIT/384KHZ, NATIVE DSD512 SUPPORT
ACRO CA1000 features premium sound using Astell&Kern’s proven technology.
You can enjoy your favorite music to your heart's content with support for native DSD512 and 32bit/384kHz PCM playback.
Bit-to-bit playback is possible up to 32-bit/384kHz PCM and 22.4MHz native DSD, so even the smallest details the artist wanted to express in the music can be heard without distortion.

PREMIUM SOUND ANYWHERE
ACRO CA1000 features powerful output with various input and output options that can only be found in a stationary headphone amplifier. A portable amplifier that can operate without an external power source adds utility beyond existing products.
A headphone amp should be able to deliver perfectly noise-free sound for an extended period of time. The ACRO CA1000 is equipped with an 8,400mAh large-capacity battery to provide clear, distortion-free premium sound without the need for a separate power connection.
In order to solve the problem of relatively reduced playback time due to the small size and powerful output, all power-related parts were examined and the power circuit was redesigned several times. The result is continuous playback for more than 10 hours. With the Astell&Kern ACRO CA1000’s excellent sound reproduction ability, you can hear the full, original sound of your music anywhere.
