This is a YAMAHA AG06. I used it for streaming with my smartphone. Power has been confirmed as shown in the image. Also, sound is coming out from the microphone and instrument outputs. The reason for being a junk item is: ① The microphone GAIN knob is broken off at the base. (You can still adjust it by pinching it with your fingertips) ② The earphone jack is slanted. Sound can still be heard. Due to the above reasons, it is a junk item. Please understand that I don't know when it might stop working. I will include the main unit and a short USB cable (about 50cm) for power. Please understand that this is based on my amateur assessment. I will disinfect it with alcohol after taking the photos. Please ask any questions in the comments. YouTube Streaming IRIAM Mirrativ 17 Live Instagram Recording Interface
