why my voice is echoing when it comes out of the amplifier? I tried to adjuct the microphone and it didn't work. the classroom for 100 students.

Try adjusting the reverb knob and keep the mic farther away from the speaker. It may also help to keep speaker slightly in front of the mic to prevent the echoing.... Similar to bands on stage. The amplifiers/speakers are closer to the audience to prevent sound feedback or distortion.

Can you speak through the microphone and play a recording from tf (micro sd) or usb flash drive at the same time?

Yes, you may speak and play a recording from tf/usb flash drive, we thought people may use it to sing a song with the music in the tf/usb flash drive. enjoy it!

In a smaller room will this give us feed back?

I use it in an average size classroom with very minimal feedback and only sporadically

Good at first, but I RETURNED IT.

The item died on me for some reason. I returned it, and they gave me a refund. The item is good, but maybe not durable.
