Thank you for viewing. This is a listing for a Solid State Logic (SSL) SSL2 USB audio interface. It was "almost only set up" in my home's sub-environment, so the frequency of use was quite low, and it is generally in beautiful condition. It works without any problems, and you can use it immediately upon arrival. ■ Condition Confirmed to be in normal working order Overall clean condition Small scratches on the back (see photo 5) Knobs, switches, and terminals are all in good condition Used in a smoke-free and pet-free environment ■ Included Accessories (complete) Original box USB cables (2 types) Instruction manual and all documents Internal packing material included (safe for transportation) ■ Product Features Equipped with a high-quality SSL microphone preamplifier "4K switch" for a warm, analog-like sound quality Easy-to-use 2-in / 2-out model Widely compatible with composing, recording, streaming, narration recording, etc. ■ Delivery Carefully packed and shipped in the original box + cushioning material.
