This is a passive DI (Direct Injection) box that does not require power. I used it twice at home and once in the studio. It's in very good condition, with the manual and original box, and has been tested and confirmed to be working. It's perfect for those looking for a low-cost DI that doesn't color the sound. While most live houses have DIs, some studios don't. I used this to recreate a performance-like environment in the studio anytime. The regular price at Soundhouse is ¥5,980 (as of 2025/12/3).
