Aurora UI and Color Display

The D70 Pro OCTO features a full-color screen with three touch buttons, offering a refreshed and intuitive user experience. The display provides playback information, FFT, and VU meter options, which can be customized to your preferences. The Aurora UI enhances the visual appeal and interaction with the device.

The device supports switching between Chinese and English language interfaces, selectable during the initial setup.

Bluetooth 5.1 Transmission

Experience high-quality wireless audio with Bluetooth 5.1 support, including advanced audio encoding formats such as LDAC, aptX-Adaptive, aptX HD, aptX, AAC, and SBC. This ensures a stable and superior sound experience when streaming wirelessly.

Plug and Play Compatibility

The D70 Pro OCTO boasts wide compatibility across multiple operating systems, including Windows 10, Windows 11, macOS, Linux, and iOS/Android. Simply connect the device to your audio source for immediate use.

For Windows users, ASIO applications require driver installation and setup using the XMOS XU316 hardware and Thesycon custom driver. Other operating systems function without the need for a specific driver.

Versatile Output Modes

The D70 Pro OCTO offers flexible output options, including single-ended RCA and balanced XLR outputs. Users can choose to activate only the desired output channel or use both simultaneously, catering to various system configurations and output needs.

Additionally, the device provides selectable output levels for XLR (4V/5V) and RCA (2V/2.5V), allowing for adaptation to a wider range of devices and optimized performance.

Integrated Preamp Function

Beyond its DAC capabilities, the D70 Pro OCTO includes an integrated preamp mode. In this mode, the device can directly control volume and output to power amplifiers or active speakers, simplifying your audio setup.

Independent Volume Memory

The D70 Pro OCTO intelligently memorizes the output volume for "Single Ended", "Balanced", and "All" modes. Upon selecting a mode again, the device automatically recalls the last used volume setting.

12V Trigger Interface

Equipped with a 12V Trigger input and output interface, the D70 Pro OCTO can be synchronized with other devices for power on/off operations. This feature allows for seamless integration and automated control within your audio system.

Best Match: A70 Pro

The Topping A70 Pro serves as an ideal companion to the D70 Pro OCTO, sharing identical design aesthetics. Both devices can be linked via the 12V Trigger connector for synchronized power management, ensuring a cohesive and efficient user experience for driving headphones and active speakers.

System Configuration Example

A typical audio setup may involve connecting a PC to the D70 Pro OCTO, which then outputs to a Headphone Amplifier, finally connecting to Headphones.
