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.

For Windows

To configure your Windows PC to automatically switch the indicator color on your D1P or DAC3 based on the sample rate of the audio file being played, you can use specialized audio playback software that supports this feature. Here are a few options:

Using foobar2000 with WASAPI or ASIO Plugins

foobar2000 is a popular and highly customizable audio player for Windows that can be configured to use WASAPI or ASIO for bit-perfect playback, which allows automatic sample rate switching.

  1. Download and Install foobar2000:
  2. Install WASAPI or ASIO Plugin:
    • Download the WASAPI component or ASIO component from the foobar2000 components page.
    • Install the component by dragging the downloaded file into the foobar2000 Components window (File > Preferences > Components).
  3. Configure Output:
    • Go to File > Preferences > Playback > Output.
    • Select your DAC under the WASAPI or ASIO output device.
  4. Enable Bit-Perfect Playback:
    • Ensure that your DAC is set to "Event" or "Push" mode (for WASAPI) or the correct ASIO driver.
    • This configuration will allow foobar2000 to automatically switch the sample rate based on the source material.

Using JRiver Media Center

JRiver Media Center is another powerful media player that supports automatic sample rate switching.

  1. Download and Install JRiver Media Center:
  2. Configure Output Mode:
    • Go to Tools > Options > Audio.

These applications provide bit-perfect playback and ensure that your DAC receives the correct sample rate without manual configuration.

The Gen 1 24-bit D1 requires a USB 2.0 cable to work properly. If your computer has USB-C inputs, use a 2.0 USB cable with a type C-to-A USB adapter.

- The process for replacing a volume encoder begins with pulling the volume knob straight back from the encoder shaft

- Make sure the rubber insert stays with the volume knob - 

- The volume encoder shaft should look like so before proceeding - 

- Using a thin-walled 10mm socket, remove the lock nut fastening the encoder to the front of the speaker cabinet - 

- Once you have removed the amp backplate on the back of the active speaker, make sure to remove the encoder wiring terminal clip from the amp circuit board. You can then fully uninstall the encoder assembly by pulling back the encoder shaft from the inside -

- Finally, the IR receiver can be removed by using a long-necked Phillips PH1 screw driver to remove the 2 screws fastening the IR receiver on the inside of the cabinet - 

After fully removing the faulty encoder, the replacement can be installed following these steps in reverse order before finally connecting the wiring clip to the amp circuit board and fastening the amp backplate back onto the active speaker.

The process can be a bit cramped if you wish to do as little disassembly as possible, or a bit easier if you are comfortable moving parts to give yourself more workspace. The sound damping insulation normally overlaps at the bottom of the active cabinet. This can be peeled back similar to the reference picture attached. The crossover is mounted underneath this insulation (If process being done on an HD6) and is perhaps the most obtrusive part when replacing a volume encoder. This has two Philips head screws mounting it to the base of the cabinet along with an adhesive pad to reduce noise vibration. It is possible to remove the two screws and lift the adhered crossover up from the base of the cabinet momentarily to get better access to the IR receiver and volume knob assemblies at the front. If you'd rather not risk damaging anything, the IR receiver can still be unscrewed from the inside of the cabinet with a long-necked Phillips PH1 driver. The volume knob is loosened from the outside of the cabinet with a thin-walled 10mm socket found by pulling the volume knob straight back  from the encoder shaft. Ample lighting will also make this work easier
