Channel DJ Mixer with USB

I know someone back in my native country, the Philippines, who is recently into DJing. At first I did not expect her to be interested in music at all much more so into DJ gear and accessories because she was a quiet type of person. Actually, she just bought a gear like a numark 2 channel mixer. She has posted a picture of herself and the gear on social media. That’s how I found out what she has been up to lately. She said she has been using it for her gigs during fiesta celebration.
