For sale: Roland GO:MIXER PRO-X. This is an audio mixer specifically designed for smartphone streaming. By connecting this device, your instruments, and your smartphone with the included cables, you can record videos with decent sound quality (though there may be a slight loss of audio fidelity). I purchased it about two years ago and used it until recently to post performance videos on X (formerly Twitter) and Instagram. I have confirmed that the videos are working. I'm selling it because I've upgraded to new equipment. The included accessories are as follows: * Main unit * Three cables (for iOS, Android, and a 4-pole cable) (Manual and original box are not included) It will be shipped via Yamato Transport in a 60-size box. Please consider this a used item. Thank you for your understanding.
