I purchased this used online. ※Reasons for the low price / Important points: • The box was in the condition shown in the images at the time of purchase, and the product showed signs of aging. • The coil part of the battery compartment was rusty, and I removed some of the rust myself to get it to power on. (Images 5, 6) It works without any problems, but please be aware of this. I am selling this because it was not compatible with the microphone I own. (I have confirmed that it can be used for recording and streaming with a different microphone) Interface
