Absolutely! If you use the USB input of the D2 Sender, then connect the D2 Receiver optical output to your DAC and the D2 will act as a wireless 24-bit USB-to-SPDIF converter and stream high-resolution digital audio to your favorite DAC. You can also use the optical input on the D2, in which case the […]
We chose optical over coax inputs and outputs for D2 (and D1) primarily because TVs, Apple TV, and computers all have optical outputs. Regarding optical vs. coax quality, there are various thoughts and theories on which is better but our experience is that as long as optical is implemented correctly and the connectors are high-quality, […]
The D2 Sender can simultaneously broadcast to (3) D2 Receiver units. See the Pairing section in the D2 Setup Guide for pairing additional receivers.
If you use a wireless 802.11g router, set the channel to either 1 or 11. If you have a 2.4G WLAN-N access point in your home, make sure it is set to 20MHz bandwidth and not 40MHz.
No. The volume information is transmitted via a completely separate I2C channel over the air and is used at the output of the internal DAC of the D2 Receiver to attenuate an analog output.
The D2 uses “adaptive mode” in it’s USB receiver. This means that the USB receiver (Texas Instruments 1020B) will keep track of the data coming in from the computer and adjust so as not to miss any incoming data. Due to the nature of the wireless link, the data then becomes asynchronous before arriving at […]
If using a Mac, open the Audio MIDI Setup utility in Applications->Utilities, choose “Audioengine D2” under audio devices and check that the format is set to 96 and the bit depth is set to 24bit.
USB cable performance will vary with construction and length, however, for the best results we recommend using the shortest cable possible (2′ or less).
The free Remote app for iTunes works nicely on an iPhone/iPad and there are plenty of free apps for non-iTunes based systems as well as Android-based apps.
Yes! You will need an Apple USB camera adapter, and a self powered USB hub. We’ve tested this with the D-link DUB-H4 and DUB-H7, and it works well. Here’s an example of how this would be connected: iDevice w/ USB Camera Adapter –USB-> Powered hub –USB-> D2 Sender –wireless-> D2 Receiver –RCA-> Speakers
