Why are you running 48 volts phantom power on a dynamic mic? They don't need it. A condenser mic needs phantom power in order to operate. You could do damage to a dynamic mic by applying 48 volts. Be careful.

Good eye, but please look one more time. Phantom power was off when testing (Red light indicating phantom power was off/blue light indicating preamp was on only) I should have included the explanation about the switch on the preamp board, but my main goal was not about the product from Amazon, but to show viewers about one possible solution among hundreds of solutions. Thanks for your comments

I accidentally applied phantom power to my dynamic mic a few times, but luckily nothing happened Following is what I found from Shure.com, and it might be helpful for you ☆☆☆☆☆☆☆☆☆☆ Will Phantom Power Damage My Dynamic Mics? ☆☆☆☆☆☆☆☆☆☆ A dynamic microphone, like the SM58, does not require phantom power because it does not have active electronics inside. Nonetheless, applying phantom power will not damage other microphones in the vast majority of cases. The reason is that modern dynamic microphones are designed to accept phantom power without issues, but we advise checking your manual or consulting with the manufacturer first before connecting; particularly if you have a ribbon microphone. Additionally, it's a good idea to turn phantom power off while plugging and unplugging microphones to prevent any potential power surge and general pops and loud noises, which could damage your speakers/headphones over time
