Potential Downsides

While the AR-M20 has many strengths, it's not without its potential downsides. One of the main drawbacks is the price. It sits at a premium price point, which may put it out of reach for some. Another thing to consider is the lack of streaming service support.

The AR-M20 has some limitations that should be weighed against its strengths.

Common Issues and How to Troubleshoot

Let's talk about some common issues that users might encounter with the AR-M20 and how to troubleshoot them. If you're having trouble with the device not turning on, make sure it's fully charged. The battery might be depleted. If that doesn't work, try a reset. You can often find instructions on how to do this in the user manual. If the sound quality seems off, double-check your headphone connection and make sure your audio files are of high quality. Low-quality files will sound poor on any DAP. If you're experiencing issues with file transfer, make sure your USB cable is working properly. Then try a different USB port on your computer. Sometimes, the computer's USB port isn't providing enough power. If the device freezes or becomes unresponsive, try a soft reset. This usually involves holding down the power button for a few seconds. If problems persist, consider checking for firmware updates. These updates often address bugs and improve performance. Sometimes the issues can be caused by corrupted files. If that is the case, try deleting the file and re-uploading the file.

If you're experiencing connectivity issues with Bluetooth, make sure the other device is in pairing mode and within range. Try forgetting the device on both the AR-M20 and the other device. Then try pairing them again. If you're having trouble with the microSD card, make sure it's properly inserted. Format the card in the AR-M20 itself to make sure it's compatible. Also, make sure that it's formatted in a compatible format such as FAT32. For any other problems, refer to the user manual or contact Acoustic Research support. They can provide more specific instructions or potential solutions. By following these troubleshooting steps, you should be able to resolve most common issues with the AR-M20.
