Powerful Audio Anywhere, CA1000

Introducing the Astell&Kern CA1000 Carriable Headphone Amp.
The ACRO CA1000 is a headphone amplifier that combines the functions and portability of a high-performance amplifier and DAP based on Astell&Kern’s fundamental philosophy of delivering original sound.

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.

Supports a Wide Range of Inputs/Outputs

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).

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.

Faster Charging with USB-PD 2.0 Support

The ACRO CA1000 features USB-PD 2.0 charging that supports 9V/3A for faster charging. When used with a USB-C adapter that supports USB-PD 2.0 fast charging, the ACRO CA1000 can charge to 50% in one hour, and fully charge in about 2 hours and 30 minutes.

Speaker Effect When Listening Through Headphones – Crossfeed

Crossfeed mixes parts of the original signal from one channel and sends that signal to the opposite channel with a time difference to center the sound image.

Through the use of detailed settings such as Shelf Cutoff, Shelf Gain, and Mixer Level, you can set the level of crossfeed according to your listening preferences.

Equipped with Bluetooth 5.0 and Support for Wireless 24-Bit aptX-HD, LDAC Codecs

The latest Bluetooth version provides high sound quality with the convenience of wireless playback to headphones and IEMs. Bluetooth 5.0 features faster transmission speed, greater range and a more stable wireless connection when compared to Bluetooth 4.2. Both LDAC and aptX HD is supported to provide audiophiles with the best wireless sound possible.

Wireless Hi-Fi Sound Through BT Sink

The newly introduced BT Sink function connects the CA1000 to an external device via Bluetooth, similar to connecting a smartphone with a BT speaker.
Music from an external device, such as a smartphone can now be played back in high-quality on the CA1000 using the BT Sink function.
