The Gemini PMX 01 DJ mixer is DJ equipment with gain, sound quality adjustment, and cue volume adjustment functions. I have confirmed that sound is output from both channels. Line/Phono inputs are also working correctly. The adapter is not included. Please purchase an AC/AC 15V adapter on Rakuten. It was not sold on Amazon. Please make sure not to mistake it for an AC/DC adapter. - Brand: Gemini - Model: PMX 01 - Cue Volume Adjustment: Yes - Output Terminals: Master Output, Phono, Line - Controls: Gain, Treble, Bass, Cue 1, Cue 2
