If you are experiencing issues with your speakers when connected via USB on a Windows 10+ operating system, it might be due to the DCH (Declarative, Componentized, Hardware Support Apps) drivers. While DCH drivers offer many benefits, they can sometimes cause compatibility issues with USB audio devices, resulting in problems such as delays when sound starts, poor audio quality, or the speakers not being recognized properly.

Solution: To resolve these issues, we recommend switching from DCH drivers to non-DCH (standard) drivers. Here’s a step-by-step guide to help you do that:

1. Uninstall the Current DCH Drivers:
   
2. Download the Non-DCH Drivers:
   
3. Install the Non-DCH Drivers:
   
4. Restart Your PC:
   

By switching to non-DCH drivers, the compatibility issues with your USB speakers should be resolved, allowing you to enjoy optimal audio performance.

Additional Tips

• Check for Firmware Updates: Ensure your speakers have the latest firmware installed. Visit the manufacturer’s website for firmware updates that may improve compatibility and performance.
  
• USB Ports: Try connecting your speakers to a different USB port to see if the issue persists.
  
• Contact Support: If you continue to experience issues, please contact our customer support team. Provide details about your operating system, motherboard model, and the specific problems you are encountering.
  

We hope this helps you resolve any issues and enhances your experience with our speakers. If you have further questions or need assistance, don’t hesitate to reach out to our support team.

2) What kind of battery goes in the remote that came with my Audioengine system? 

The Audioengine remote takes a CR2025 battery.

3) How do I know if I bought from an
authorized and legitimate site?

Audioengine operates two websites,
audioengine.com and audioengineeu.com. If you go to any other site but these,
they are not an Audioengine site. For Canada, Mexico and most of Europe and the
UK, we only sell through Amazon. There are also a host of authorized retailers
and sites across the US, and they can be found here. For
international sales, we have distributors that operate independently, and they
can be found here. 

What happens if I buy from an
authorized site claiming to be Audioengine? Unfortunately, there is not much we
can do. We are taking all the action we can to make sure those sites don't get indexed,
but we recommend you work with the provider of the card you used to make
payment to get your money back.

All turntables require a phono preamp stage before connecting to
Audioengine speakers. Many turntables have this built-in , while others do not and would require an external phono preamp. Check the turntable manufacturer’s website or user manual. Some turntables may even include Bluetooth, in which case you can pair and connect them to the speakers wirelessly!

Not necessarily. Audioengine speakers and amplifiers are very efficient. Also, we designed them together as a system; so, we therefore get more volume output than stereo receivers or amplifiers that might have higher wattage or power numbers. Due to this tuning, we achieve big sound outputs with a fraction of the power required by other systems.

Yes, you can. The A2+ Wireless speakers use a switching power supply so it will automatically convert to the different voltage. The power cable is also detachable which makes it convenient to replace the AC plug with a different type if you don’t want to use an adapter plug.

Absolutely! You will need to pick up Apple's Lightning to USB 3 Camera Adapter, which allows a USB connection to the iPad (and, as of iOS7, the iPhone). Then just hook up as you would from a computer. You can even charge your iPhone or iPad while you use it this way!

Our woofers are made of aramid fiber and the tweeter domes are silk. Both of these materials are very robust and can handle quite a bit of abuse. For our A-series speakers we decided against grill covers as they do tend to color the sound a bit. However, without speaker grills they are more cat and kid-friendly! If you do prefer speakers with grills, you can check out our HD3 speakers here.

No. The Bluetooth and USB inputs both share the internal DAC for
processing, so you can only listen to one at a time, with Bluetooth
taking priority. If you're using USB for example, and start using
Bluetooth, the USB signal will cut and Bluetooth will take over.
Depending on your source, if you pause or disconnect from Bluetooth the speakers may automatically switch back to USB after a few seconds.

Though overall latency can be affected by some external factors (including but not limited to signal strength, and even simply being physically further away from the speakers), Bluetooth on the A2+ Wireless generally has a delay of about 30ms (milliseconds) so you should be able to watch videos from Youtube, for example, and stream out the audio to the A2+
Wireless without any significant or noticeable lag between the video and audio.

Once your A2+ Wireless is paired and connected via Bluetooth, then any app (TIDAL, Music, Spotify, etc.) will automatically play your music through Bluetooth.

No extra software or drivers are needed. The A2+ Wireless is compatible with any device that supports Bluetooth, and the A2DP profile for streaming stereo audio. This includes most smartphones, tablets, and computers. For computers that don't include BLuetooth support out of the
box, you can simply add a USB Bluetooth adapter.

The same is also true for the USB connection on the A2+, which uses
plug-and-play drivers provided by your computer's OS. The A2+ USB input is compatible out of the box with Windows and Mac computers, iPhones and iPads when using Apple's lightning USB 3 adapter along with a fast wall charger, and should work with most Android Smartphones and Tablets as
well.

In most cases, Yes! The overall range you can expect will vary depending on the device you use with the A2+ Wireless, as well as things like the type of construction used in walls you'll be transmitting through. In our testing, most mobile devices like smartphones and tablets will have the best range, some of which can exceed 100 ft in good conditions, even through one wall. Laptops and desktop computers in our testing generally had less overall range with an average of around 70 ft in similar good conditions through a single wall.

The A2+ Wireless work excellent via Bluetooth, but they can also be used wired, with more traditional source devices like Turntables, CD players, or anything else with a standard analog audio connection like RCAs or 3.5mm stereo-mini. They also include a USB port for use with a Windows or Mac computer, as well as many Smartphones and Tablets with the right USB adapter cable.

You can absolutely still use the A2+ Wireless and it will sound great. AptX is a high-quality Bluetooth audio codec that works really well. In addition aptX, and the default Bluetooth codec SBC, The A2+ Wireless support other high quality audio codecs, like AAC for use on Apple iPhone and iPads, as well as Android devices that do not include aptX.

Yes they do! They are equipped with a power-saving circuit that turns off the speaker's final stage amp. This idle mode activates right after you stop playing music. Due to this power-saving function, it's perfectly fine for the speakers to stay on all the time!
