PreSonus Revelator io24 USB Audio Interface Contents: Main unit, USB-C to A cable, Japanese manual, English manual, 4 anti-slip stickers, original box Built-in effects allow for relatively easy implementation of reverb, compression, and other effects. The control app with mixer functionality is quite user-friendly, and the audio routing can be adjusted, so I used it for live streaming. I think it has hardly been used. The LCD protective film has not been peeled off. Non-original anti-slip pads are attached to the bottom. The box is also relatively clean. This is a discontinued product, but I recommend it to streamers. (It can do something similar to the old AG03, and in my subjective opinion, the sound quality was better.) *Since the manufacturer's page is gone, please download the driver software separately from the following links.
