This is a microphone activator and microphone preamplifier made by CloudMicrophone. It uses an XLR cable to connect to a dynamic microphone, boosting the gain by 25dB. Phantom power is required for use. I don't remember when I bought it, but it has been tested and is in working order. It has been used very little and is in good condition. The box and cable are not included. Please check the photos carefully before purchasing, as this is a used item. ■Original Price: 27,800 yen ■Model Name: Cloudlifter CL-1 ■1-channel version ■Power: Phantom power ■Input/Output Connectors: Input 1x XLR, Output 1x XLR ■Size: 47mm, 114mm, 48mm T12-01YM
