This is a Sound Blaster AE-9. I purchased it from the official shop on May 11, 2022. The ACM has some scratches. The main unit is also slightly dusty, but I have only performed minimal cleaning, considering the risk of damage during cleaning. I was using a condenser microphone with it until recently, so there are no issues with its operation. I am selling some other items as I am organizing my equipment. Please take a look if you are interested.
