The D70 Pro OCTO Topping DAC is packed with the refinements of a high-end audio product. With its high-performance chips (8x CS43198), ultra-low jitter clocks, latest-generation interfaces and great versatility, this converter offers exceptional audio reproduction, characterized by magnificent transparency and richness of sound, as well as practical, useful features.
The D70 PRO OCTO features no less than 8 CS43198 DAC chips, enabling it to support PCM audio streams up to 32bit 768kHz and DSD up to DSD512.
This DAC supports the best Bluetooth formats such as LDAC, aptx-Adaptive and apt XHD. High-resolution files can therefore be transmitted to it for a superb listening experience, all with the convenience of wireless.
The extraordinary measurements of the OCTO D70 Pro ensure a very rich and detailed level of sound reproduction.
The OCTO D70 Pro has a wide system compatibility: Windows 10, Windows 11, Mac OS, Linux, IOS, Android. Simply connect it to your audio source and start playing. The USB plug is based on the XMOS XU316 chip and a custom Thesycon driver, so it's very stable.
A driver and settings are required for the ASIO application on Windows.
With its multitude of functions and connectors, Topping's D70 PRO OCTO can be integrated into the vast majority of audio systems, offering numerous options for use and installation. Input connections include AES/EBU, Coaxial SPDIF, Optical Toslink and USB.
Outputs include balanced XLR and unbalanced RCA. The D70 PRO OCTO lets you select the output so as to send the audio stream to just one of them, or to both at the same time.
In addition, XLR 4V and RCA 2V outputs can be boosted to XLR 5V and RCA 2.5V.

The D70 PRO OCTO also acts as a preamplifier, since it includes a volume controller. This volume control function can be deactivated, however, so that the D70 PRO OCTO can be used only as a DAC with output levels constantly at their maximums, i.e. 4Vrms for the XLR output and 2Vrms for the RCA output.
This function enables the D70 PRO OCTO to be controlled or to control other devices so that they can be switched on and off simultaneously.
The D70 Pro OCTO comes with a new color screen and 3 control buttons for an even better experience. What's more, this screen can display certain information (FTT and VU) according to your needs.
