With 16 channels for microphones, phono inputs, and line inputs, it offers plenty of flexibility for various setups. The digital mixer also includes a 4-band equalizer to help adjust and fine-tune audio levels. The sleek black design and reliable Behringer brand make this mixer a great choice for professionals and hobbyists alike. Units will have random make power supplies. Plus they are used and may have some glue residue on them from labels placed on them identifying channels. This unit the volume knob has been bent. I tried to show it from two different angles to show it. It’s not broke and it works just like it’s supposed to. But it is bent a small amount. I haven’t tried to straighten it because it’s plastic and it may break. But also because it’s working perfectly so other than a cosmetic look it doesn’t hurt a thing
