An essential item for those who want to record vocals, such as for "Utaってみた" (I tried singing) videos, onto their PC! A power supply box for microphones, equipped with an XLR cable and USB connection. Connect from the microphone to this unit, and from this unit to your PC or smartphone to record professional-quality microphone audio! - Type: XLR Cable - Connection Terminals: USB Connection - Power Switch: ON/OFF Switch Thank you for viewing. I purchased this a few years ago but didn't use it much and left it unused. I am selling it due to moving. Thank you for your consideration.
