Can I use the D2 with an Apple iPhone or iPad?
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:
phone and tablet w/ USB Camera Adapter –USB-> Powered hub –USB-> D2 Sender –wireless-> D2 Receiver –RCA-> Speakers
I have the original Audioengine 5 (not the A5+), will the D1 / D2 DAC work with the inputs on that original model?
You can use Audioengine DACs with your original A5s, no problem. You would simply use a standard RCA cable and the RCA to mini-jack adapter that came with the A5 to connect the RCA output from the DAC in to one of the mini-jack inputs.
If the D2 DAC Sender is connected to my MacBook in another room do I have to go back to the computer to change songs?
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.
Where can I download drivers for the D2?
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.
What is the best USB cable length to use with D2?
USB cable performance will vary with construction and length, however, for the best results we recommend using the shortest cable possible (2′ or less).
Can I connect the D2 Sender to a USB hub?
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.
I’m hearing a crackling/popping sound when playing music. What am I doing wrong and how can I fix this?
When issues do crop up in USB audio, this is a common symptom. The PDF linked below outlines the issue and potential causes as well as some common fixes.
Will the D2 work with USB 1.1?
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.
How do I make sure that the D2 DAC is set to 24-bit/96KHz audio?
If using a Mac, open the Audio MIDI Setup utility in Applications->Utilities, choose “Audioengine D1” under audio devices and check that the format is set to 96 and the bit depth is set to 24bit.
I’m having trouble using my D2 with Foobar in WASAPI and KS mode. What do I do?
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.
Is there an easier way for Mac users to get to System Preferences and the Audio MIDI Setup control panels?
A customer recommended an app called Soundsource – http://rogueamoeba.com/freebies – which is an easy way to switch between audio input and outputs as well as to access System Preferences and the Audio MIDI control panels.
Is there a recommended “break-in period” for the D2?
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 first before doing any critical listening.
Is the D2 USB isochronous or asynchronous?
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 the Receiver. Thus the D2 acts as an asynchronous USB DAC with the added benefit of being 24/96 bit-perfect wireless.
Will the volume control on the D2 Sender affect my audio?
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. Will the D2 interfere with my other wireless devices? 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.
What can I do to further ensure that all my wireless devices work well together?
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.
How many wireless “zones” can I set up with D2?
The D2 Sender can simultaneously broadcast to (3) D2 Receiver units. See the Pairing section in the D2 Setup Guide for pairing additional receivers.
Why does D2 have a digital optical but no coax interface?
We chose optical over coax inputs and outputs for D2 (and D1) primarily because TV’s, 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, it is essentially the same digital SPDIF signal.
Can I use D2 to connect my computer wirelessly to another DAC in my audio system?
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 D2 will act as a wireless optical link to your DAC. Can I use a third-party (non-Audioengine) AC power adapter to power my D2 Sender and/or Receiver? The D2 AC power adapters have been specifically designed to provide stable low-noise power to the D2 so only use the included Audioengine power adapters. Using any other power adapter will compromise the audio quality and may damage your D2.
Can I take my D2 to another country with a different voltage?
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.
What is the AC power cord type for Audioengine D2?
We use 2-pin non-polarized IEC 320-C7 cables, which is common and can be purchased at most electronics stores.
How does D2 differ from the Audioengine W1 or W3 wireless adapters?
The D2 offers bit-perfect 24/96 transmission, while the W1 and W3 wireless are 16-bit adapters (16/44.1 and 16/48KHz).
