This is the Roland USB audio interface "QUAD-CAPTURE (UA-55)". It's a used item, but its operation has been confirmed. I'm selling it because I'm reorganizing my equipment. I've used it for many years with CUBASE and other software, and it allowed me to do various productions, such as microphone recording and digital output, despite its compact size. The item for sale is the main unit only. I aim for quick responses and same-day shipping to ensure a smooth transaction. Thank you for looking. #Roland #QUADCAPTURE #UA55 #AudioInterface #USBAudio #DTM #HomeRecording #StreamingEquipment #UsedAudio
