Audioengine D2 Premium 24-bit Wireless DAC

Audioengine D2 Premium 24-bit Wireless DAC allows you to stream wireless HD audio from your computer to any music system, independent of your Wi-Fi network. D2 has USB and optical inputs, a high-performance DAC, plus the isolation benefits of wireless. Setup is fast and simple, with no software to install and without the frustration of trying to connect to your network.

Audioengine D2 is Versatile

The D2 is actually three products in one - a high-quality USB wireless computer DAC, a wireless USB-to-SPDIF converter, and a wireless optical PCM-to-stereo link. The ability to stream HD audio wirelessly from your computer direct to your music system not only keeps your computer away from your audio gear, but also minimizes nagging problems such as ground loops, induced cable noise, and jitter. And if you already have a favorite DAC, the D2 can provide bit-perfect wireless USB-to-SPDIF conversion or serve as a wireless link for your PCM-stereo stream.

Audioengine D2 Designed for the Computer Audiophile

The D2 sends a 24bit/96KHz PCM stereo digital stream over-the-air in a "closed-system" Wi-Fi configuration. The system's proprietary RF technology ensures data integrity with no impact on existing routers or networks. The volume control on the D2 Sender is transmitted over an entirely separate channel so there is no impact on the digital audio stream.

Audioengine D2 Easy Setup

Bypass your computer's sound card or headphone jack and send wireless HD audio to any music system. D2 transmits all music file formats from any computer media player and can simultaneously transmit HD audio to up to 3 wireless receivers. The 100ft (30m) typical range, low latency, built-in DAC, and resistance to interference and dropouts makes D2 the best-sounding HD wireless system available.

Audioengine D2 See and Hear the Difference

Audioengine designers, with your attention to audio quality as well as visual aesthetics, have created a feast for both the eyes and ears. The rounded anodized aluminum case of the D2 reflects traditional Audioengine design and the audio fidelity is typical of Audioengine's commitment to great sound at an affordable price. The Audioengine D2 continues to close the gap between your computer music and home hi-fi and even if you're not an audio enthusiast we guarantee your music will sound better!

Audioengine D2 Advantages of wireless

The D2 wireless system transmits bit-perfect PCM-stereo simultaneously to up to 3 receivers. This PCM stream is routed from/to the various components of the system (optical transmitter/receiver, USB controller, and DAC) via the I2S bus, which maintains data integrity throughout the system. Because the various source/sink components are segregated by the wireless subsystem, various anomalies which plague many wired DACs such as jitter, grounding, and induced cable noise are greatly reduced. In addition, the D2 allows the user to physically isolate a potentially noisy computer from the sensitive audio components in your system.

Audioengine D2 USB

The D2 utilizes the TI1020B USB controller chip, widely recognized as the industry standard for higher-end USB audio products. The Sender can be powered directly from the USB bus or from the included external power adapter. The USB power is passed through two stages of regulation to ensure high stability and low noise.

Audioengine D2 DAC

The D2 Receiver utilizes the PCM1792 DAC, widely know for it's low noise and high fidelity. Due to the PCM1792's high signal-to-noise specs and the added benefit of triple redundancy power source conversion and filtering, the D2 presents impressive low noise and low distortion characteristics.

Audioengine D2 I2C Volume Control

The D2 incorporates a separate-path wireless channel to transmit volume information from the Sender volume control to the analog section of the Receiver. This means that the volume information never affects the digital audio stream.

Audioengine D2 and LAN

The D2 system divides the band between 2405 MHz and 2477 MHz into 37 discrete, 2 MHz wide channels. Channels numbered 2 through 38 inclusive are used for system operation. The system scans the spectrum and selects two channels that are 18 channels (or 36 mHz) apart and transmits with 50% of the time on one channel (for example channel 2) and 50% on the other channel (for example channel 20). The system stays on these selected channels until the error detection rate reaches a pre-determined level indicating deteriorating RF conditions. The system will then select a cleaner channel for transmission and move there without any drop in audio. In this way the D2 not only maintains it's own audio integrity, but co-exists nicely with other LAN devices.
