Game-Changing Computer Audio

Audioengine D2 DAC offers audio hi-fi and features of DACs that cost several times more and with a plus one essential feature – it’s wireless! D2 is a simple to use a yet powerful digital-to-analog converter. The performance and features are mostly found in much more expensive DACs. The D2 processes digital audio at any bit depth up to 24 bits and sample rates to 192 kHz, and then sends your music over-the-air at 24/96. It works fine with USB or PCM-stereo optical and will automatically configure to match either of these inputs.

Product Description

Easy Setup and Simple Operation

Setting up the D2 units to pair with either an Apple Mac Book or Windows desktop and the primary audio system took less time than unpacking and reading the brief but informative manual. D2 allows you to transmit and control a digital audio signal from one place, and receive it as either a digital or DAC-converted analog signal elsewhere. Bypass your computer’s sound card or headphone jack and send wireless HD audio to any music system. And if you have music of different file formats from your computer media player, D2 has got you covered 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 are the features that make D2 the best-sounding HD wireless system available.

Versatile

If you call D2, three products in one; you are right! It is a high-quality USB wireless computer DAC, a wireless USB-to-SPDIF converter, and a wireless optical PCM-to-stereo link. D2 can stream HD audio wirelessly from your computer directly to your music system and also minimizes nagging problems such as ground loops, induced cable noise, and jitter. This will allow you to keep your computer away from your audio gear. 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.

Join the Computer Audio Revolution

There’s no need to have to synchronize anything or install anything on a computer, or even use a computer at all. 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 was built to ensure 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. Interestingly, the volume is always at the same level for the same position of the volume control, as it should be.

See and Hear the Difference

Listening to the D2 DAC, the one word that keeps coming to mind is “smooth.”  The D2 is a budget DAC that successfully avoids the dreaded listener fatigue. Paying much attention to audio quality and visual aesthetics, Audioengine D2 DAC is a must have. The rounded anodized aluminum case of the D2 reflects the typical Audioengine design, and the hi-fi depicts Audioengine’s commitment to great sound at an affordable price. A product with high standard and more value for the money; even if you’re not an audio enthusiast we guarantee your music will sound better!

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.

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.

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.

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.

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.
