AudioEngine D2, Setup Manual

5

The D2 can process digital audio at any bit depth up to 24 bits, and 

any sample rate up to 192KHz.  The D2 USB input can accept a USB 

audio stream from your computer or other USB source device.  The D2 

optical input can accept optical (PCM stereo) streams from any optical 

(TOSLINK) source, such as computers, TVs, Apple TV, DVD/BluRay 

players, CD players, etc.  

Note

:  Optical sources must be set to PCM Stereo.

The D2 Receiver output can be connected to any gear with an analog 

(RCA or minijack) audio input, such as powered speakers, stereo 

system, etc.

The D2 Receiver also includes an optical output, which can be used to 

connect your own DAC or stereo receiver.  Thus the D2 system can act 

as a wireless USB to S/PDIF converter, as well as a wireless optical link!

Power for the D2 Sender can be provided via USB or the included 

power adapter.  

Note

:  Use only the provided Audioengine power adapter.  The 

Audioengine adapter is specifically designed for maximum audio 

performance, and the use of other adapters may damage your D2.

Note

:  When using the D2 with the optical output of your computer, 

the USB port on the computer can provide power.  The D2 will sense 

that an optical input is present and give that input priority.  

Internally, USB power is “double regulated” to ensure that no USB bus 

power variations affect the audio.

The D2 Sender can simultaneously broadcast to (3) D2 Receiver units.  

See the Pairing section for pairing additional receivers.
