※ Operation confirmed. All accessories are included, and you can use it immediately upon arrival. This is an ammoon AGM02 USB audio interface built-in mixer. 【Operation Check】 Power on and electrical current confirmed. Connected a microphone and tested sound output, and it worked normally. Can be used as an audio interface via USB connection. 【Condition】 The main unit has little signs of use overall and is in relatively clean condition. There are no noticeable scratches or damage, but there are areas on the surface that appear to have faint oil (sebum) marks, although they are not dirt or scratches. I tried to wipe them off, but they did not disappear completely. This does not affect use. The original box has scratches and scuffs from storage. 【Accessories】 ・Main unit ・USB cable ・Instruction manual ・Original box Since not all functions have been thoroughly checked, we do not guarantee all functions.
