PreSonus 18/24 audio interface. I used this for home recording, recording with 5 or more microphones. I am selling it because I now use fewer microphones. I haven't used it very often. It appears to be in good condition with no noticeable scratches, but please forgive any oversight as I am a layman. Regarding the sole on the back, some of the adhesive has melted, but the sole itself is firmly attached.
