A2+ Wireless Speaker System (Open Box)

This issue occurs because some computers fail to "wake up" the USB port after a period of inactivity. While our A2+BT uses UPnP drivers for maximum compatibility, the USB connection is identified as an external DAC by most systems. Recent operating system updates for Mac and Windows have made this issue more frequent. 

1. What solutions can I try to resolve this issue? 

The solution often requires trial and error based on your specific computer setup. Many customers have found helpful tips and solutions in the following resources: 

• For Mac users: Apple Community Thread 

• For Windows users: StarTech USB Issues FAQ 

2. Is there a difference in audio quality when using USB/Bluetooth versus analog connections? 

Yes, there is a difference. Here’s what you need to know: 

• USB/Bluetooth Connection: This uses the digital-to-analog converter (DAC) built into the A2+BT speakers, which is 16-bit. 

• Analog Connection (RCA or 3.5mm inputs): This uses the DAC in your computer or device. Since most modern computers support 24-bit or even 32-bit audio, you’ll achieve better sound quality when using an analog connection. 

3. How do I know which connection type is best for me? 

• If you prioritize convenience or wireless functionality, USB or Bluetooth is a great choice. 

• If you’re looking for the highest audio fidelity, consider using analog connections like RCA or a 3.5mm mini-jack.

If you're looking to enhance the bass on your A2+ Home Music System, there are a few steps you can take to achieve the sound you're looking for:

1. Speaker Positioning:
   The placement of your speakers can have a significant effect on bass performance. Try placing the speakers closer to a wall, which can naturally amplify the bass. Additionally, ensure that the surface they're on is stable, as vibrations can impact sound quality.
2. Use of Equalizer Software:
   Windows 11 has built-in sound enhancements, but for more detailed control over the bass and other sound frequencies, we recommend using third-party equalizer software. One highly recommended option is a DSP correction software specifically designed for A2+ Home Music System. You can find more details about this software and how to use it in this article: Enhancing Audioengine A2+.

This software allows for precise adjustments of the bass and other sound settings to give you a more customized listening experience.

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:
   • Open the Device Manager on your PC.
   • Locate your audio device under "Sound, video, and game controllers."
   • Right-click on the device and select "Uninstall device."
   • Ensure you check the option to delete the driver software for this device to completely remove the DCH drivers.
2. Download the Non-DCH Drivers:
   • Visit the support website of your motherboard or computer manufacturer.
   • Navigate to the driver download section and find the non-DCH Realtek (or appropriate) audio drivers for your system.
3. Install the Non-DCH Drivers:
   • Download and run the installer for the non-DCH drivers.
   • Follow the on-screen instructions to complete the installation process.
4. Restart Your PC:
   • After installing the non-DCH drivers, restart your computer to apply the changes.

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.

1. Turn Off and Unplug:

• Make sure your system is turned off and unplugged.

2. Dust the Surfaces:

• Use a soft, dry cloth to wipe away dust.
• For hard-to-reach places, use a soft brush or a can of compressed air.

3. Wipe Down the Exterior:

• We do not recommend using any solvents
• If cleaning off stains or build-up is necessary, we recommend doing so with a very small amount of mild cleaning solution applied only to the affected area, followed by quickly wiping the area dry completely. 
• Any scoured pads or objects like a 'magic eraser' too easily run the risk of removing sealers and top coats of the painted finish that can leave a clearly visible change in the uniformity of the paint/finish

4. Clean the Speaker Grills:

• The speaker grills can be gently cleaned with a vacuum, preferably using a soft bush attachment.
• A lint roller can also be used.

5. Clean Buttons and Knobs:

• A dry cloth is recommend for cleaning any knobs, buttons or other surfaces
• Be careful not to let water get into any gaps.

6. Clean Ports and Connections:

• Use compressed air to blow out dust from ports and connections.

7. Let Everything Dry:

• Make sure everything is completely dry before plugging back in and turning on.

8. Regular Cleaning:

• Dust your system regularly to keep it in good shape.

By following these steps, you can keep your Audioengine system clean and working well.

Each speaker is 6" (15.2 cm) x 4" (10.2 cm) x 5.25" (13.3 cm)

Absolutely!  You can connect any Audioengine speaker with an analog output to any Sonos product that has the Line-In feature.  You can also connect any Audioengine passive speakers into an existing Sonos system using the Sonos Amp.

Absolutely! To do so:

• Open the Alexa App on your smartphone or tablet (Apple link  |  Google Play Link)
• Tap the “Devices” icon and select the Echo/Alexa device you want to connect to speakers
• Select “Bluetooth Devices”
• Select “Pair New Device”
• Find your Audioengine wireless speaker on the list of available Bluetooth devices, and select it

Yes! We incorporate all the relevant functions and features from Bluetooth 5.0 that apply to our products! These features include; extended range, low latency (so that video and audio sync properly), as well as higher level aptX-HD, aptX, and AAC codecs (with the exception of our 512 portable speaker which supports SBC only). Keep in mind that the capability of the source is what controls the Bluetooth experience.

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!
