This listing is for the main unit and AC adapter only. It's a 12-channel analog mixer with built-in effects and a 3-band EQ. - Model Name: 1202FX - Brand: Behringer - Input Terminals: XLR, TRS - Output Terminals: Main Out, CTRL ROOM OUT, TAPE OUT - Effects: Built-in effects - EQ: 3-band EQ - Phantom Power: Yes - Number of Channels: 12 channels - Size: Compact I only checked the operation immediately after purchasing it new, and it has been stored in a duralumin case ever since. I am selling it now to organize my equipment. I have checked the power and input test with an electric-acoustic guitar before listing. Since it has been stored for a long time, please understand that it is a used item. Thank you for looking.
