Product Description

Audioengine D2 Premium Wireless 24-bit DAC streams wireless HD audio from PC to any music system, independent of your wifi network. It has USB and optical inputs, a high-performance DAC plus wireless support.

Set Up in Seconds

Bypass your computer’s sound card and transmit high-res wireless audio to any music system. D2 transmitter accepts USB or optical inputs and the D2 Receiver output optical or analogue audio. The 100ft (30m) range, low latency and opposition to interference and dropouts make D2 a superior HD wireless system. Setup is effortless with no need to install software or driver and without the frustration of trying to link to your network.

Three in One

D2 Wireless DAC is a three in one unit; a wireless USB computer DAC, USB-to-SPDIF converter, and a digital optical-to-stereo link. Support for streaming high-res audio wirelessly from PC direct to your music system distances your computer from audio gear minimising issues such as ground loops, induced cable noise and jitter.

Hear the Difference

D2 Wireless DAC offers audio fidelity and DAC properties associated with units costing several times more. D2 handles digital audio at up to 24 bit depth and to 192KHz sample rates then relays your music over-the-air at 24-bit/96kHz (in comparison to 16-bit/44.1kHz W1 and 16/48KHz W3 adapters). It accepts USB or PCM optical and configures itself to match either input. Volume data is transmitted via an entirely isolated I2C channel and used at the internal DAC output to attenuate an analogue output.


D2 transmits bit-perfect PCM-stereo to up to 3 receivers simultaneously. This is directed between components (optical transmitter/receiver, USB controller and DAC) via the I2S bus which retains data integrity throughout the system. Since the source/sink components are separated by the wireless subsystem, common anomalies of wired DACs such as jitter, grounding and induced cable noise are lowered.


D2 employs the industry standard TI1020B USB controller chip used in premium USB audio products. The transmitter can be powered straight from the USB bus or from the external power adapter. USB power is passed through two stages of regulation to grant top stability and least noise. D2's USB receiver uses "adaptive mode", keeping track of data from the PC and adjusts it so no incoming data is missed. The nature of the wireless link means data becomes asynchronous before arriving at the Receiver. It is recommended that you position the D2 at least 12" from other wireless products.


The D2 Receiver employs the PCM1792 DAC, renowned for it’s low noise and high fidelity. Due to the PCM1792’s high signal-to-noise specs and the benefit of triple redundancy power source conversion and filtering, the D2 presents incredible low noise and distortion characteristics.

I2C Volume Control

D2 uses a separate-path wireless channel to convey volume data from the Sender volume control to the analogue section of the Receiver so as to never affect the digital audio stream.

Key Features

- Plug-n-play functionality
- Broadcast to up to 3 receivers
- Precision re-clocking for low jitter
- Asynchronous data transfer
- USB + optical inputs
- Optical and analog outputs
- Digital volume control on separate channel
