        The ACRO CA1000T has a battery protection mode feature that helps extend battery life. When battery protection mode is enabled, the battery is charged up to 85%, and then the charge stops. If the battery drops below 80%, the battery will start charging again and charge up to 85%.

        Enjoy the ACRO CA1000T's powerful sound while being optimized for longer with the ACRO CA1000T's battery protection mode.

        *Battery protection mode will be supported through a firmware update.

        Real-Time Information Using Light

        The LED light reminiscent of the vacuum tube light allows you to check bit depth information of currently playing music or the amp mode being used.

        Playback mode - 16bit: Red / 24bit: Green / 32bit: Blue / DSD: Purple
        Amp mode - OP AMP: Red / Tube Amp: Orange / Hybrid Amp: Blue Green

        Silver Plating Shield Can

        A shield can is applied to prevent various noise and electromagnetic interference from affecting the audio block. The ACRO CA1000T takes a step further to achieve excellent audio performance and perfect shielding by applying highly conductive, high-purity silver on the existing shield can and physically separating digital and analog signals.

        AK File Drop to Enjoy Wireless Transfers

        The new AK File Drop function in the CA1000T makes files transfers easier and more convenient.

        Using AK File Drop, you can freely transfer files wirelessly through a PC, smartphone, or FTP program located on the same network.
        Music file management is now possible with a cableless, wireless solution.

        Supports Native DSD512, 32bit/768kHz

        ACRO CA1000T supports Native DSD512 and up to 32bit/768kHz with Astell&Kern's excellent audio technology, allowing you to fully enjoy your favorite music.

        MQA 16X Full Decoder and Optical In/Out Support

        The ACRO CA1000T supports the MQA 16X Full Decoder via the hardware renderer.  In addition, MQA sound sources can be input and output through Optical In/Out.

        *Input: Hardware rendering of the primary unfold signal of the connected output device*Output: CA1000T outputs signal after MQA primary unfold

         

        ReplayGain Automatically and Uniformly Adjusts Playback Volume

        ReplayGain, which adjusts sound sources with different volumes to an identical level, has been applied. Now, enjoy your own playlists seamlessly through the ReplayGain feature on the ACRO CA1000T.

        *ReplayGain supports up to 24bit/192kHz sound sources.

        Wireless Hi-Fi Sound Through BT Sink

        BT Sink function connects the ACRO CA1000T 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 ACRO CA1000T using the BT Sink function.
