Setup Guide


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.
