We take great pride in our products, and go through great lengths to ensure consistency and quality. For that reason, this item was randomly selected for an additional step of Quality Assurance.

When using the optical input of the D1 DAC or the HD6 speakers, you'll need to make sure your TV's audio output is set to PCM (not Dolby, DTS, or 5.1/surround).  Special hardware is needed to process Dolby audio signals.  If your TV is set to Dolby, it's likely you'll hear some audio but it will be intermittent in nature with dropouts.  Once the output is set to PCM, this should resolve the issue.  Check with your TV manufacturer for directions on how to make this adjustment.

The D2 is designed to play well with most wireless devices, especially computers and routers. We do, however, recommend that you locate the D2 at least 12" from other wireless products.

We use 2-pin non-polarized IEC 320-C7 cables, which is common and can be purchased at most electronics stores.

Your D2 will sound great out of the box and will get better over time.  However, it's best to play music for 40 to 50 hours before doing any critical listening.

In the Foobar control panel, under Preferences->Output, set the buffer length to minimum. A few customers have mentioned that WASAPI mode is more stable when used under WinAmp, so try that as well.

Yes, however, note that 24/96 HD digital audio pushes the limits of USB 1.1 speeds. Due to this, it's highly recommended that you connect to a higher speed USB 2.0 port.

Although D2 may work just fine when connected to most USB hubs, this is not recommended as the data rate may not be fast enough for higher-resolution music. We therefore suggest you select a high-speed USB bus all by itself and don't use a USB port on your keyboard, for example.

The D2 is a USB Plug-and-Play audio device. This means that the drivers it uses are developed and provided by the developer of your computer’s operating system. In the case of a Windows PC for example, these drivers are provided by Microsoft, and are a part of Windows.

The following diagrams show the most common configurations for D2 Setup.

Note: For maximum range, ensure that both antennae are upright.

USB from your computer

Step 1 -- Connect the D2 Sender to your computer USB port.

For PC, the D2 should be recognized automatically.

For Mac, under System Preferences/Sound, select “Audioengine D2”

Step 2 –- Connect the analog output of your D2 Receiver to any audio input of your active speakers, stereo, etc.

Step 3 -- Connect the D2 power adapter to the D2 Receiver, and to an AC power source.

Optical Source

Step 1 -- Connect an optical output of your computer, TV, Blu-Ray, DVD, etc. to the optical input of the D2 Sender.Step 2 -- Connect the D2 power adapter to the D2 Sender, and to an AC power source.Note: Verify that your source is set to PCM Stereo.

Step 3 –- Connect the analog output of your D2 Receiver to any audio input of your active speakers, stereo, etc.

Step 4 -- Connect the D2 power adapter to the D2 Receiver, and to an AC power source.

Pairing

Pairing is the function by which two devices become acquainted. Once a Sender and Receiver(s) are paired, they will remember one another.

Note: D2 Senders and Receivers packaged together are paired out of the box, so if you’re only using one Sender/Receiver set, no further configuration is needed.

To pair an additional Receiver or to re-pair a Sender/Receiver set, press the Pair button on the Receiver (the Pair LED will blink), then press the Pair button on the Sender. Both Sender and Receiver pair lights should now be solid, indicating that they are paired.

D2 Setup Video

The D2 offers bit-perfect 24/96 transmission, while the W1 and W3 wireless are 16-bit adapters (16/44.1 and 16/48KHz).

Yes, D2 uses switching power supplies so they will automatically convert to the different voltage. The AC power cord is detachable which makes it convenient to replace the AC plug with a different type if you don't want to use an adapter plug.
